复合金属CuCr2O4表面CNCl水解反应机理
Hydrolysis reaction mechanism of CNCl on the surface of composite metal CuCr2O4
摘要
Abstract
This study systematically investigated the reaction mechanism of the hydrolysis of highly toxic and difficult to hydrolyze cyanogen chloride(CNCl)on the surface of spinel-type bimetallic oxide CuCr2O4 catalyst.Based on density functional theory,by constructing perfect and oxygen vacancy defect models of(100),(110)and(111)crystal planes,the surface stability,adsorption characteristics and hydrolysis pathways were analyzed.Research showed that different crystal plane structures and oxygen vacancy defects jointly regulate the hydrolysis path and reaction energy barrier,among which the(110)oxygen vacancy surface exhibits the best catalytic synergy.A predictive model of adsorption energy and reaction energy was constructed,revealing that the electronic synergy and site complementarity mechanism between Cu and Cr is key to improving hydrolysis efficiency.This work provides a theoretical basis for designing efficient bimetallic hydrolysis catalysts.关键词
