Abstract
Extraction of valuable metals such as gold from electronic wastes (e-waste) is regarded as a promising way of environmental remediation; however, this process is still confronted with the cost-ineffective product for normal usages like electronic devices or jewelry. Therefore, there would be merits in directly converting gold from e-waste to materials of higher value, for example, catalysts for pollutant treatment. Herein, a porous aromatic framework (PAF) with cationic sites, named iPAF-7, was synthesized and exhibited rapid extraction of gold from e-waste. Au@iPAF-7 completely converted nitroarenes to arylamines within 10 s at a rate constant of 7.8 × 10-2 s-1, which is much higher than that of any other gold nanoparticle (AuNP) catalysts with solid supports reported so far. Furthermore, considering the limitations and difficulties of operating powder materials, the aerogel monolith incorporating iPAF-7 was successfully fabricated, which retained the excellent gold extraction ability and catalytic activity of its powder form, thus exhibiting its potential application for continuous-flow catalysis of nitroarene reduction.

Bimetallic nanocomposite (Ag-Au, Ag-Pd, Au-Pd) synthesis using gum kondagogu a natural biopolymer and their catalytic potentials in the degradation of 4-nitrophenol. Int J Biol Macromol 2021; 190:159-169.

Abstract
Bimetallic nanoparticles (BNPs) constitute two different metal elements and exhibit relatively superior mechanistic and catalytic efficacies owing to their synergistic functions over monometallic nanoparticles. In the present study various bimetallic Ag-Au, Ag-Pd, Au-Pd nanoparticles were synthesized using a natural biopolymer gum kondagogu (GK) as a reducing and capping agent, by a simple and cost-effective method. The synthesized BNPs when characterized using UV-vis spectroscopy revealed a specific surface plasmon resonance band (SPR) of each nanocomposite. The average particle size of Ag-Au, Ag-Pd, and Au-Pd BNPs was found to be 23 ± 10.3, 21 ± 7.6, and 23 ± 9.4 nm respectively based on transmission electron microscopy analysis. Surface morphology and functional groups on the gum matrix of GK-BNPs were analyzed by XRD and FT-IR respectively. The bimetallic nanocomposites were evaluated for their catalytic reduction of 4-nitrophenol (4-NP) to 4-aminophenol in the presence of NaBH4. The kinetic studies performed, depicted rate constants for Ag-Au, Ag-Pd, and Au-PdNPs as 0.31, 0.39, and 0.28 min-1 respectively. The catalytic efficiencies of three bimetallic nanocomposites were of the following order Ag-Pd > Ag-Au > Au-Pd. This study establishes the catalytic potentials of the three different bimetallic nanocomposites in the reduction of 4-NP an environmental pollutant, and the impact of their synergistic property.

Abstract
We report the first preparation of small gold-nickel (AuNi) bimetallic nanoparticles (<5 nm) supported on titania by the method of galvanic replacement reaction (GRR), evidenced by the replacement of Ni atoms by Au atoms according to the stoichiometry of the reaction. We showed that this preparation method allowed not only the control of the gold and nickel contents in the samples, but also the formation of small bimetallic nanoparticles with strained core-shell structures, as revealed by aberration-corrected scanning transmission electron microscopy in combination with energy-dispersive X-ray spectroscopy mapping. The catalytic characterization by the probe reaction of semi-hydrogenation of butadiene showed that the resulting nickel-based nanocatalysts containing a small amount of gold exhibited higher selectivity to butenes than pure nickel catalysts and a high level of activity, closer to that of pure nickel catalysts than to that of pure gold catalysts. These improved catalytic performances could not be explained by a mere structural model of simple core-shell structure of the nanoparticles. Instead, they could come from the incorporation of Ni within the gold surface and/or from surface lattice relaxation and subsurface misfit defects.

Abstract
Ag/TiO2 nanocomposites with controlled crystallization and properties were prepared by a simple solvothermal method. By using the same raw materials with different ratio and reaction conditions, the morphologies and crystallization of nanocomposites can be tuned. The components of the products were analyzed by TEM and XRD methods respectively. The as-prepared Ag/TiO2 nanocomposites were used as surface-enhanced Raman spectroscopy (SERS) substrate to be evolved for detection of environmental organic dyes pollutants (CV and RhB) with excellent recyclability. Furthermore, it also showed enhanced catalytic performance of nitrophenol compounds (4-NP). After that, the Ag/TiO2 nanocomposites were also used as an active substrate and a superior catalyst for reduction of 4-NTP monitored by Raman spectroscopy.

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.

Abstract
This paper reports the development of robust Pd- and Ru-containing magnetically recoverable catalysts in a one-pot procedure using commercially available, branched polyethyleneimine (PEI) as capping and reducing agent. For both catalytic metals, ∼3 nm nanoparticles (NPs) are stabilized in the PEI shell of magnetite NPs, whose aggregation allows for prompt magnetic separation. The catalyst properties were studied in a model reaction of 4-nitrophenol hydrogenation to 4-aminophenol with NaBH4. A similar catalytic NP size allowed us to decouple the NP size impact on the catalytic performance from other parameters and to follow the influence of the catalytic metal type and amount as well as the PEI amount on the catalytic activity. The best catalytic performances, the 1.2 min-1 rate constant and the 433.2 min-1 turnover frequency, are obtained for the Ru-containing catalyst. This is discussed in terms of stability of Ru hydride facilitating the surface-hydrogen transfer and the presence of Ru4+ species on the Ru NP surface facilitating the nitro group adsorption, both leading to an increased catalyst efficiency. High catalytic activity as well as the high stability of the catalyst performance in five consecutive catalytic cycles after magnetic separation makes this catalyst promising for nitroarene hydrogenation reactions.

Abstract
Bimetallic gold-silver nanoparticles as unique catalysts were prepared using seed colloidal techniques. The catalytic capabilities of the nanoparticles were ascertained in the reduction of 4-nitrophenol to 4-aminophenol in the presence of sodium borohydride. Our results clearly showed that the rate of 4-NP reduction to 4-AP increased with a corresponding decrease in the diameter of the bimetallic NPs. The Au-Ag nanoparticles prepared with 5.0 mL Au seed volume indicated higher reduction activity, which was approximately 1.2 times higher than that of 2.0 mL Au seed volume in the reductive conversion of 4-NP to 4-AP. However, the monometallic NPs showed relatively less catalytic activity in the reductive conversion of 4-NP to 4-AP compared to bimetallic Au-Ag nanoparticles. Our studies also reinforced the improved catalytic properties of the bimetallic Au-Ag nanoparticles structure with a direct impact of the size or diameter and relative composition of the bimetallic catalytic nanoparticles.

Abstract
We herein report the preparation of unique heteroatom-doped and carbon-based AuAg alloy nanoparticles (NPs) via the pyrolysis of a structurally defined octanuclear heterometallic Au(i)-Ag(i) cluster [Au4Ag4(Dppy)4(Tab)4(MeCN)4](PF6)8 (2, Dppy = diphenylphosphine-2-pyridine and Tab = 4-(trimethylammonio)benzenethiolate). This cluster-precursor approach exerts a fine control over the spatial arrangement, size and uniformity of the AuAg alloy NPs as well as the doped heteroatoms (P, N, F and S). The optimized material prepared at 450 °C efficiently catalyzes the oxidative coupling of anilines to yield azobenzenes under mild conditions.
