Avalos-Ballester V, Acosta B, Smolentseva E. Remarkable Enhancement of Catalytic Reduction of Nitrophenol Isomers by Decoration of Ni Nanosheets with Cu Species. ACS OMEGA 2024; 9:37981-37994. [PMID: 39281961 PMCID: PMC11391462 DOI: 10.1021/acsomega.4c04762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 08/14/2024] [Accepted: 08/21/2024] [Indexed: 09/18/2024]
Abstract
Herein, the catalytic reduction of isomers of nitrophenols (NPS) using Ni x Cu y nanostructures with different molar ratios is presented. Ni x Cu y catalysts are prepared using star-shaped Ni nanoparticles as seeds. The applied synthesis transforms Ni nanoparticles into sheet-like structures when Cu species are deposited on them. The bimetallic sheet-like Ni x Cu y nanostructures demonstrate high catalytic activity to reduce NP isomers concerning their monometallic counterparts. The contribution of the Cu+ species affects the catalytic reduction of the NPS isomers. For example, the catalytic reduction of 4-nitrophenol (4-NP) depends on the Ni:Cu molar ratio: Ni1.75Cu > Cu > NiCu > Ni7Cu > Ni3.5Cu > Ni. The Ni7Cu catalyst exhibits the highest catalytic activity in the reduction of nitrophenol isomers 2-nitrophenol (2-NP) and 3-nitrophenol (3-NP), and the obtained results are comparable with those reported for noble-metal-based catalysts. The low-cost production of Ni x Cu y catalysts and their high catalytic stability and availability make them attractive for industrial applications.

Abstract
In this study, we synthesised the Ni/single-walled carbon nanotube prepared by the super-growth method (SG-SWCNTs). In this approach, the Ni nanoparticles were immobilised by an impregnation method using the SG-SWCNTs with high specific surface areas (1144 m2g-1). The scanning electron microscopy images confirmed that the SG-SWCNTs exhibit the fibriform morphology corresponding to the carbon nanotubes. In addition, component analysis of the obtained samples clarified that the Ni nanoparticles were immobilised on the surface of the SG-SWCNTs. Next, we evaluated the activity for the reduction of 4-nitoropenol in the presence of the Ni/SG-SWCNTs. Additionally, the Ni/graphene, which was obtained by the same synthetic method, was utilised in this reaction. The rate of reaction activity of the Ni/SG-SWCNTs finished faster than that of the Ni/GPs. From this result, the pseudo-first-order kinetic rate constantkfor the Ni/SG-SWCNTs and the Ni/GPs was calculated respectively at 0.083 and 0.070 min-1, indicating that the Ni/SG-SWCNTs exhibits higher activity.
