摘要
CO_2化学利用对碳资源利用、化解产能过剩、完善相关产业链有重要意义,CO_2转化催化剂研究因此受到广泛关注。针对具有规模应用前景的CO_2加氢合成甲醇、CO_2甲烷化和甲烷CO_2重整催化剂研究现状与存在问题,讨论了计算催化和催化剂强化制备在研究新型高效CO_2转化催化剂中的重要应用,说明了CO_2负离子的潜在应用价值;以等离子体强化制备催化剂为例,强调了多学科交叉的重要性。讨论了制备有利于传热、活性组分优化的结构化催化剂在进一步改进催化剂活性中的重要作用。指出了CO_2温室效应的复杂性,还有一些问题(如人类活动对地球磁场影响进而对气候的影响)并不清楚,强调了加强基础研究对解决这些问题的重要性。
CO_2 utilization has received worldwide attention. Effective utilization of CO_2 becomes an urgent challenge. As such, developing catalysts and catalytic processes for effective CO_2 conversion will contribute positively to reducing net CO_2 emission. Recent developments of catalysts for CO_2 hydrogenation to methanol, CO_2 methanation and CO_2 reforming of methane have been briefly reviewed. In particular, novel catalysts developed through computational catalysis and intensified catalyst preparation were presented. The importance of CO_2 anion in CO_2 reduction has been discussed. The plasma enhanced catalyst preparation was used as an example to demonstrate the importance of the multi-disciplinary efforts. Catalysts with optimized structures for heat transfer performance and distribution of active sites for CO_2 conversion have also been discussed. Because of the complexity of global warming, some issues（for example the influence of change in the terrestrial magnetic field induced by human activity） are still not clear and call for more fundamental studies.
