英文摘要	Various CuO-ZnO/Al2O3 catalysts have been synthesized by citric acid sol-gel auto-combustion method and their performances for methanol synthesis from CO2 hydrogenation have been investigated. The effects of citric acid/nitrate ratio on physicochemical, morphologies and catalytic properties were studied by BET, XRD, SEM, XPS and H2-TPR. Catalytic activities of the prepared catalysts for methanol synthesis were tested in fixed-bed flow reactor. The results indicated that when 100% of stoichiometric amount of citric acid was used, the CuO-ZnO/Al2O3 catalyst exhibited an optimum catalytic behavior. The catalyst showed relatively smaller particle size, higher surface area and more uniform Cu dispersion.
