Ramírez O, Bonardd S, Saldías C, Leiva A, Díaz Díaz D. Highly efficient and reusable CuAu nanoparticles supported on crosslinked chitosan hydrogels as a plasmonic catalyst for nitroarene reduction. ENVIRONMENTAL RESEARCH 2024; 247:118204. [PMID: 38224938 DOI: 10.1016/j.envres.2024.118204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 01/09/2024] [Accepted: 01/12/2024] [Indexed: 01/17/2024]
Abstract
The synthesis of CuAu-based monometallic (MNPs) and bimetallic nanoparticles (BNPs) supported on chitosan-based hydrogels for their application as catalysts is presented. The hydrogels consisted of chitosan chains cross-linked with tripolyphosphate (TPP) in the form of beads with an approximate average diameter of 1.81 mm. The MNPs and BNPs were obtained by the adsorption of metallic ions and their subsequent reduction with hydrazine, achieving a metallic loading of 0.297 mmol per gram of dry sample, with average nanoparticle sizes that were found between 2.6 and 4.4 nm. Both processes, metal adsorption and the stabilization of the nanoparticles, are mainly attributed to the participation of chitosan hydroxyl, amine and amide functional groups. The materials revealed important absorption bands in the visible region of the light spectra, specifically between 520 and 590 nm, mainly attributed to LSPR given the nature of the MNPs and BNPs inside the hydrogels. Subsequently, the hydrogels were evaluated as catalysts against the reduction of 4-nitrophenol (4NP) into 4-aminophenol (4AP), followed by UV-visible spectroscopy. The kinetic advance of the reaction revealed important improvements in the catalytic activity of the materials by synergistic effect of BNPs and plasmonic enhancement under visible light irradiation, given the combination of metals and the light harvesting properties of the nanocomposites. Finally, the catalytic performance of hydrogels containing BNPs CuAu 3:1 showed an important selectivity, recyclability and reusability performance, due to the relevant interaction of the BNPs with the chitosan matrix, highlighting the potential of this nanocomposite as an effective catalyst, with a potential environmental application.

Abstract
The Wittig reaction is a key step in industrial processes to synthesise large quantities of vitamin A and various other important chemicals that are used in daily life. This article presents a pathway to achieve the Wittig reaction in a solid network. A highly porous triphenylphosphine-based polymer was applied as a solid Wittig reagent that undergoes, in a multi-step cycle, in total six post-synthetic modifications. This allowed for regeneration of the solid Wittig reagent and reuse for the same reaction cycle. Of particular industrial relevance is that the newly developed material also enables a simple way of separating the product by filtration. Therefore, additional costly and difficult separation and purification steps are no longer needed.

Abstract
Current applications of multifunctional nanozymes for reprogramming the redox homeostasis of the tumor microenvironment (TME) have been severely confronted with low catalytic activity and the ambiguity of active sites of nanozymes, as well as the stress resistance from the rigorous physical environment of tumor cells. Herein, the Sm/Co-doped mesoporous silica with 3PO-loaded nanozymes (denoted as mSC-3PO) are rationally constructed for simultaneously inhibiting energy production by adenosine triphosphate (ATP) inhibitor 3PO and reprogramming TME by multiactivities of nanozymes with photothermal effect assist, i.e., enhanced peroxidase-like, catalase-like activity, and glutathione peroxidase-like activities, facilitating reactive oxygen species (ROS) generation, promoting oxygen content, and restraining the over-expressed glutathione. Through the optimal regulation of nanometric size and doping ratio, the fabricated superparamagnetic mSC-3PO enables the excellent exposure of active sites and avoids agglomeration owing to the large specific surface and mesoporous structure, thus providing adequate Sm/Co-doped active sites and enough spatial distribution. The constructed Sm/Co centers both participate in the simulated biological enzyme reactions and carry out the double-center catalytic process (Sm3+ and Co3+ /Co2+ ). Significantly, as the inhibitor of glycolysis, 3PO can reduce the ATP flow by cutting down the energy transform, thereby inhibiting tumor angiogenesis and assisting ROS to promote the early withering of tumor cells. In addition, the considerable near-infrared (NIR) light absorption of mSC-3PO can adapt to NIR excitable photothermal treatment therapy and photoexcitation-promoted enzymatic reactions. Taken together, this work presents a typical therapeutic paradigm of multifunctional nanozymes that simultaneously reprograms TME and promotes tumor cell apoptosis with photothermal assistance.

Recovery of Homogeneous Platinoid Catalysts from Pharmaceutical Media: Review on the Existing Treatments and the Perspectives of Membrane Processes. MEMBRANES 2023; 13:738. [PMID: 37623799 PMCID: PMC10456598 DOI: 10.3390/membranes13080738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 08/14/2023] [Accepted: 08/16/2023] [Indexed: 08/26/2023]
Abstract
Catalyst recovery is a major challenge for reaching the objectives of green chemistry for industry. Indeed, catalysts enable quick and selective syntheses with high reaction yields. This is especially the case for homogeneous platinoid catalysts which are almost indispensable for cross-coupling reactions often used by the pharmaceutical industry. However, they are based on scarce, expensive, and toxic resources. In addition, they are quite sensitive and degrade over time at the end of the reaction. Once degraded, their regeneration is complex and hazardous to implement. Working on their recovery could lead to highly effective catalytic chemistries while limiting the environmental and economic impacts of their one-time uses. This review aims to describe and compare conventional processes for metal removal while discussing their advantages and drawbacks considering the objective of homogeneous catalyst recovery. Most of them lead to difficulty recycling active catalysts due to their ability to only treat metal ions or to chelate catalysts without the possibility to reverse the mechanism. However, membrane processes seem to offer some perspectives with limiting degradations. While membranes are not systematically the best option for recycling homogeneous catalysts, current development might help improve the separation between pharmaceutical active ingredients and catalysts and enable their recycling.

Abstract
The electrochemical conversion of CO2 into value-added chemicals is an important approach to recycling CO2. In this work, we have combined the most efficient metal catalysts for this reaction, namely Cu, Ag, and Au, as single-atom particles dispersed on a two-dimensional carbon nitride support, with the aim of exploring their performance in the CO2 reduction reaction. Here, we report density functional theory computations showing the effect of single metal-atom particles on the support. We found that bare carbon nitride needed a high overpotential to overcome the energy barrier for the first proton-electron transfer, while the second transfer was exergonic. The deposition of single metal atoms enhances the catalytic activity of the system as the first proton-electron transfer is favored in terms of energy, although strong binding energies were found for CO adsorption on Cu and Au single atoms. Our theoretical interpretations are consistent with the experimental evidence that the competitive H2 generation is favored due to the strong CO binding energies. Our computational study paves the road to finding suitable metals that catalyze the first proton-electron transfer in the carbon dioxide reduction reaction and produce reaction intermediates with moderate binding energies, promoting a spillover to the carbon nitride support and thereby serving as bifunctional electrocatalysts.
