Bruno L, Scuderi M, Priolo F, Falciola L, Mirabella S. Enlightening the bimetallic effect of Au@Pd nanoparticles on Ni oxide nanostructures with enhanced catalytic activity. Sci Rep 2023; 13:3203. [PMID: 36828859 PMCID: PMC9957992 DOI: 10.1038/s41598-023-29679-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Accepted: 02/08/2023] [Indexed: 02/26/2023] Open
Abstract
Bimetallic decoration of semiconductor electrodes typically improves catalytic and sensing performances because of a well-claimed synergistic effect. A microscopic and quantitative investigation of such an effect on energy bands of semiconductor can be really useful for further exploitation. Au, Pd and Au@Pd (core@shell) nanoparticles (10-20 nm in size) were synthesized through chemical reduction method and characterized with scanning and transmission microscopy, Rutherford backscattering spectrometry, cyclic voltammetry electrochemical impedance spectroscopy and Mott-Schottky analysis. The nanoparticles have been used to decorate Ni-based nanostructured electrodes with the aim to quantitatively investigate the effect of decoration with mono or bimetallic nanoparticles. Decorated electrodes show higher redox currents than bare ones and a shift in redox peaks (up to 0.3 V), which can be ascribed to a more efficient electron transport and improved catalytic properties. These effects were satisfactorily modeled (COMSOL) employing a nano Schottky junction at the nanoparticle-semiconductor interface, pointing out large energy band bending (up to 0.4 eV), space charge region and local electric field (up to [Formula: see text]) in bimetallic decoration. Sensing test of glucose and H2O2 by decorated Ni oxide electrodes were performed to consolidate our model. The presence of bimetallic nanoparticles enhances enormously the electrochemical performances of the material in terms of sensitivity, catalytic activity, and electrical transport. The modification of energy band diagram in semiconductor is analyzed and discussed also in terms of electron transfer during redox reactions.

Abstract
Background:
Owing to the strong oxidizing and reducing properties of hydrogen peroxide
(H2O2), it has been widely used in many fields. In particular, H2O2 is widely used in the aseptic
packaging of drinks and milk. The residue of H2O2 in food is harmful to human health. Therefore, the
quantitative detection of H2O2 is of great practical significance.
Methods:
The Ag-Au/RGO/TiO2 nanocomposites were facilely synthesized by photo-reduction approach.
Transmission electron microscopy, X-ray photoelectron spectroscopy and Raman spectroscopy
were used to characterize the synthesized Ag-Au/RGO/TiO2 nanocomposites. Cyclic voltammetry
was used to analyze the electrochemical behavior of H2O2 on the Ag-Au/RGO/TiO2/GCE.
Amperometry was applied for quantitative determination of the concentration of H2O2.
Results:
A novel Ag-Au/RGO/TiO2/GCE was prepared. The Ag-Au/RGO/TiO2/GCE displayed high
electrocatalytic activity towards H2O2 reduction. An electrochemical reduction peak of H2O2 was
achieved on the Ag-Au/RGO/TiO2/GCE. The current responses were linear with the concentrations
of H2O2 in the range of 0.01-30 mM with the detection limit of 3.0 μM (S/N = 3).
Conclusion:
An amperometric sensor has been prepared for H2O2 detection using Ag-
Au/RGO/TiO2/GCE. The Ag-Au/RGO/TiO2/GCE shows good performance for the determination of
H2O2. The proposed sensor exhibits good selectivity and stability.

TEMPO-Functionalized Nanoporous Au Nanocomposite for the Electrochemical Detection of H 2O 2. Int J Anal Chem 2018; 2018:1710438.

Abstract
A novel nanocomposite of nanoporous gold nanoparticles (np-AuNPs) functionalized with 2,2,6,6-tetramethyl-1-piperidinyloxy radical (TEMPO) was prepared; assembled carboxyl groups on gold nanoporous nanoparticles surface were combined with TEMPO by the “bridge” of carboxylate-zirconium-carboxylate chemistry. SEM images and UV-Vis spectroscopies of np-AuNPs indicated that a safe, sustainable, and simplified one-step dealloying synthesis approach is successful. The TEMPO-np-AuNPs exhibited a good performance for the electrochemical detection of H2O2 due to its higher number of electrochemical activity sites and surface area of 7.49 m2g−1 for load bigger amount of TEMPO radicals. The TEMPO-functionalized np-AuNPs have a broad pH range and shorter response time for H2O2 catalysis verified by the response of amperometric signal under different pH and time interval. A wide linear range with a detection limit of 7.8 × 10−7 M and a higher sensitivity of 110.403 μA mM−1cm−2 were obtained for detecting H2O2 at optimal conditions.

Toxicol Rep 2018; 5:468-479. [PMID: 29854618 PMCID: PMC5977415 DOI: 10.1016/j.toxrep.2018.03.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2017] [Revised: 02/23/2018] [Accepted: 03/05/2018] [Indexed: 01/04/2023] Open
Abstract
The [Zn(O)/M] (M = Mg, Al, Ca, Ti) synthesize by thermal method and characterize. The metal dopants percolate into crystal lattice of ZnO and stable it. The [Zn(O)/M] shows very low amount of Zn+2 release into culture medium. Intracellular reactive oxygen species generation decrease under UVA radiation. The [Zn(O)/M] protects of human skin cells against UVA radiation.
Application of ZnO nanoparticles in sunscreens exposes human skin with their adverse effects, which correlates to dissolution/translocation of free Zn+2 ions. The possibility of decreasing solubility and therefore, reducing toxicity, by structural modifications have been discussed as a solution. The present investigation has developed new metallic lattices of ZnO to reduce cytotoxicity of ZnO nanoparticles. Novel metal-promoted Zn-based nanocomposites ([Zn(O)/M], M = Mg, Al, Ca, Ti) were synthesized and their physicochemical properties and their cytotoxicity were evaluated. Solubility and release studies showed that modification of ZnO structure decreases release of Zn+2 into culture medium. XRD and UV absorbance analyses showed that metallic-dopants percolate into crystalline lattice of ZnO. This phenomenon is basic reason for stability of Zn-based network. Cell culture studies and MTT assay on human skin cells (HFF-1) exposed to UVA radiation showed that the level of protection of [Zn(O)/M] compounds were more than of [ZnO]. Dichlorofluoroscein diacetate-ROS assay and Zn+2 release experiments indicated that [Zn(O)/M] nanocomposites decreased the level of ROS generation and Zn+2 release in compared to ZnO, indicating higher safety of nanocomposites. This study shows that the synthesized Zn-based nanocomposites have potential to be used as safer and more effective sunscreens than ZnO.

Abstract
The emergence of nanostructured materials has opened new horizons in the development of next generation biosensors. Being able to control the design of the electrode interface at the nanoscale combined with the intrinsic characteristics of the nanomaterials engenders novel biosensing platforms with improved capabilities. The purpose of this review is to provide a comprehensive and critical overview of the latest trends in emerging nanostructured electrochemical biosensors. A detailed description and discussion of recent approaches to construct label-free electrochemical nanostructured electrodes is given with special focus on pathogen detection for environmental monitoring and food safety. This includes the use of nanoscale materials such as nanotubes, nanowires, nanoparticles, and nanosheets as well as porous nanostructured materials including nanoporous anodic alumina, mesoporous silica, porous silicon, and polystyrene nanochannels. These platforms may pave the way toward the development of point-of-care portable electronic devices for applications ranging from environmental analysis to biomedical diagnostics.

Abstract
This article presents a review of electrochemical bio-sensing for target analytes based on the use of electrocatalytic bimetallic nanoparticles (NPs), which can improve both the sensitivity and selectivity of biosensors. The review moves quickly from an introduction to the field of bio-sensing, to the importance of biosensors in today's society, the nature of the electrochemical methods employed and the attendant problems encountered. The role of electrocatalysts is introduced with reference to the three generations of biosensors. The contributions made by previous workers using bimetallic constructs, grouped by target analyte, are then examined in detail; following which, the synthesis and characterization of the catalytic particles is examined prior to a summary of the current state of endeavor. Finally, some perspectives for the future of bimetallic NPs in biosensors are given.

Abstract
Au-Ag core-shell nanoparticles have been synthesized using synthetic fluorescent dipeptide β-Ala-Trp (β-Ala is β-alanine; Trp is l-tryptophan) in water at pH 6.94 and at room temperature. The synthesis of the Au-Ag core-shell nanomaterial does not involve any external reducing and stabilizing agents, and the constituents of dipeptide β-alanine and l-tryptophan are naturally occurring. Therefore, the synthesis procedure is ecofriendly. Moreover, the shell thickness has also been controlled, and the optical property of the core-shell nanomaterial varies with the shell thickness. The core-shell nanomaterial exhibits a fascinating fluorescence property. This fluorescent Au@Ag core-shell nanoparticle can detect toxic Hg(II) ions ultrasensitively (with a lower limit of detection of 9 nM) even in presence of Zn(II), Cd(II), and other bivalent metal ions (Ca(II), Mg(II), Ni(II), Mn(II), Ba(II), Sr(II), Pb(II), and Fe(II)). Au-Ag core-shell nanomaterials can also be reused for sensing Hg(II) ions.

Abstract
A mixture of Fe(AcAc)(2) and Co(AcAC)(2) was thermolyzed in a closed cell under the autogenic pressure of the reactants. The nature of the products was temperature dependent. The reaction is a one-stage, simple, efficient, and solvent-free method to prepare FeCo alloy nanoparticles protected by a carbon shell. Particle sizes of 60-150 were obtained covered by a carbon layer of 3-4 nm. The air stability of these particles is also demonstrated.
