二氧化碳加氢合成甲醇催化剂研究进展

Recent progress in catalysts for hydrogenation of carbon dioxide to methanol

在“碳达峰、碳中和”的发展目标下,二氧化碳(CO_(2))热催化还原可以实现CO_(2)的资源化循环,还能将其转换为燃料和增值化学品。CO_(2)加氢合成甲醇是近些年最受关注的碳减排和储氢技术之一,其中高活性、高选择性、高稳定性的催化剂能够克服CO_(2)转化过程的热力学障碍并抑制副产物产生,是CO_(2)加氢制甲醇的关键环节。综述了CO_(2)加氢合成甲醇反应所用催化剂,包括Cu基催化剂、其他金属催化剂及金属氧化物催化剂的研究进展,并展望了其工业化前景。

Under the development goal of carbon peaking and carbon neutrality, CO_(2) thermal catalytic reduction can realize the recycling of CO_(2) and convert it into fuel and value-added chemicals.Carbon dioxide hydrogenation to methanol is one of the most concerned carbon emission reduction and hydrogen storage technologies in recent years.The catalyst with high activity, high selectivity and high stability can overcome the thermodynamic obstacles of CO_(2) conversion process and restrain the production of by-products, which is the key point.In this paper, the research progress of catalysts used for hydrogenation of carbon dioxide to methanol were reviewed, including Cu-based catalysts, other metal catalysts and metal oxide catalysts.And the prospect of its industrialization was also outlooked.
