The eFFect of CO on methanol synthesis From CO2 hydrogenation over Cu-Zn-Al cat-alysts have been investigated by TPSR-MS techniques and evaluated by testing the catalytic per-Formance. The results indicated that CO can Occupy part of CO2 adsorption site on the catalystsurFace to restrain the reverse water gas shiFt reaction and promote methanol synthesis in CO2hydrogenation .ThereFore it inereases the Inethanol selectivity and yield From CO2 hydrogenation.香港研究基金!RGC/96－97/02;厦门大学固体表面物理化学国家重点实验室资
