CO2 作为原料制备甲醇是一种极具前景的碳减排技术,但其工业化仍面临许多挑战.CO2 具有很强的化学惰性,在反应过程需要利用活性金属使催化剂具备较强的活化CO2 的能力以及适宜的加氢性能.本文致力于介绍目前CO2 热催化转化为甲醇的反应机理,总结了CO2 热催化加氢制备甲醇的过渡金属基、贵金属基催化剂的研究进展,并对未来研究方向进行了展望.
Advances in catalysts for methanol synthesis via thermal catalytic hydrogenation of CO2
Methanol production from CO2 is a promising carbon reduction technology,but its industrialization still faces many challen-ges.CO2 is chemically inert,and the reaction process requires the use of active metals to provide the catalyst with a strong ability to activate CO2 and suitable hydrogenation properties.In this paper,the current reaction mechanism of CO2 thermocatalytic conversion to methanol is introduced,the research progress of transition metal-based and noble metal-based catalysts for the preparation of methanol by CO2 thermocatalytic hydrogenation is summarized,and the future research directions are also prospected.
