In-situ Synthesis of Self-Supported Cu-Based Oxide Nanowires for Catalytic Hydrogenation of Nitro Compounds
摘要
Abstract
Functionalized aromatic amines serve as key components of fine chemicals and exhibit significant applications in the manufacturing of polymers,pigments,pharmaceuticals,and agrochemicals.The chemoselective hydrogenation of widely available nitroaromatics over heterogeneous catalysts represents a crucial route for the synthesis of high-value aromatic amines.Among various non-noble metal catalysts,copper-based catalysts feature abundant reserves and low cost,as well as excellent adsorption and activation performance for nitro groups in nitro compounds.However,traditional powdered copper-based catalysts tend to agglomerate during catalytic reactions,resulting in a significant reduction in catalytic activity.Additionally,they are difficult to separate and recover from the reaction system,which limits their applications in large-scale industrial production.In this work,a copper-based nanowire precursor was firstly in-situ grown on copper foam.Subsequently,the precursor was subjected to coordination with 1,3,5-benzenetricarboxylic acid(H3 BTC)and pyrolysis in an air atmosphere.Ultimately,a self-supported Cu-based nanowire catalyst with good activity and excellent stability was successfully prepared.At a reaction temperature of 25℃,this catalyst can convert 0.2 mmol/L p-nitrophenol(P-NP)to p-aminophenol(P-AP)within 3 min,and its activity remains undiminished even after 40 consecutive cycles.Notably,the catalyst can be easily separated from the liquid-phase catalytic system simply by mechanical clamping.This advantage not only addresses the problem of catalyst recovery but also effectively avoids catalyst loss during the recovery process.关键词
