CO_2制备甲醇催化剂研究进展

通过将CO2有效转化为甲醇,真正实现"跨越油气时代"进入"甲醇时代"。通常CO2加氢合成甲醇所用催化剂主要是铜基催化剂,添加其他金属元素或助剂以提高铜基催化剂催化性能。介绍CO2制备甲醇催化剂早期的研究,综述近年来有关CO2制备甲醇催化剂研究进展,新研发的镍-镓结构催化剂可在低压(常压)下将CO2转化为甲醇,比传统的铜-锌-铝催化剂更有效,更多产甲醇。介绍CO2与水反应合成甲醇反应所用催化剂以及光催化还原CO2生成甲醇的新思路和新途径。

Recent advances in the catalysts for preparation of methanol from CO2

‘Beyond oil and gas:methanol economic’ could be truly realized through effective conversion of CO₂ to methanol.In general Cu based catalysts are used for synthesis of methanol by CO₂ hydrogenation,and their catalytic performances are increased by adding other metals and additives.The research advances in the catalysts for synthesis of methanol from CO₂ hydrogenation were reviewed.Compared with traditional Cu-Zn-Al catalysts,the new nickel gallium catalyst could converted CO₂ into methanol under low pressure/constant pressure and possessed more effective catalytic performance and higher methanol output.The synthesis of methanol through the reaction of CO₂ with water and the catalyst used in the reaction were introduced.In addition,the new ideas and ways for photocatalytic reduction of CO₂ to methanolwere put forward.
