木屑衍生的Cu/Cu2O@C复合催化剂用于环己烷高效一锅法氧化制己二酸
A Cu/Cu2O@C composite catalyst derived from wood-chips for the efficient one-pot oxidation of cyclohexane to adipic acid
摘要
Abstract
Adipic acid is widely used in fine chemical synthesis,biomedicine and other industrial fields,and is a key monomer for the synthesis of nylon-6,6 and nylon-6.Industrially,it is produced by the efficient catalytic oxida-tion of cyclohexane.However,the activation of the inert C―H bonds in cyclohexane remains a major challenge in the highly selective synthesis of acid products.Using a composite catalyst of copper on a carbon support pro-duced from wood chip biomass,a green catalytic system was established for the one-pot oxidative synthesis of adipic acid from cyclohexane.Wood chips has two func-tions during pyrolysis:it acts as a carbon support precurs-or and an in-situ reducing agent,which reduces Cu2+into Cu/Cu2O active species to obtain Cu/Cu2O@C composite catalysts.The abundant defects in biomass carbon form strong co-ordination interactions with the copper active components,which effectively regulate the electronic distribution of active sites and improve the catalytic performance.Under optimized conditions(100 ℃,12 h),the Cu/Cu2O@C-0.1 catalyst achieves a cyclohexane conversion of 19.36%and an adipic acid selectivity of 73.28%.Mechanistic investigations show that the electron-ic interaction between the biomass carbon support and the copper species strengthens the adsorption of cyclohexanone,which is critical for promoting the selective formation of adipic acid.This study provides a viable strategy for developing eco-friendly,low-cost and high-efficiency advanced catalytic materials.关键词
