铜引入对锌锆固溶体催化二氧化碳加氢制甲醇的促进作用研究
Enhancement of ZnO-ZrO2 solid solution catalyst via Cu addition for CO2 hydrogenation to methanol
摘要
Abstract
The introduction of an appropriate amount of Cu effectively enhances the catalytic performance of ZnO-ZrO2 solid solution catalysts in CO2 hydrogenation to methanol.However,systematic studies on the effect of Cu content in ZnO-ZrO2 solid solution catalysts remain limited.In this work,a ZnO-ZrO2 solid solution and a series of Cu/ZnO/ZrO2-x catalysts(x=0.3,0.7 and 0.9,denoting the molar ratio of Cu/(Cu+Zn+Zr))were prepared by co-precipitation method.Among these catalysts,the Cu/ZnO/ZrO2-0.7 catalyst exhibited the optimal catalytic performance,with a space-time yield of methanol(162.7 g/(kg·h))that was 6.6 times higher than that of the ZnO-ZrO2 solid solution catalyst(24.8 g/(kg h))at 250 ℃.Structural characterizations reveal that the introduction of an appropriate amount of Cu led to the coexistence of a solid solution and individual metal oxides,and promoted the formation of medium-strength basic sites.In situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS)results further confirm that Cu introduction facilitated the conversion of key reaction intermediates.This work provides a systematic investigation of the influence of Cu content on the methanol synthesis performance of ZnO-ZrO2 solid solution catalysts and elucidates the promotional mechanism induced by Cu incorporation.关键词
