日益增长的二氧化碳排放造成了严重的环境问题，因此充分利用二氧化碳已成为研究的热点，最有效的途径之一是将CO2选择性加氢为甲醇，这不仅可以有效地减少CO2排放，而且还可以制备其他化学品和燃料。本文概述了通过直接加氢CO2进行甲醇合成重大进展。包括热力学方面的挑战，讨论了常规铜基催化剂的研究进展，包括载体和助催化剂的结构，化学和电子促进的作用等。 Increasing carbon dioxide emissions have caused serious environmental problems. Therefore, making full use of carbon dioxide has become a research hotspot. One of the most effective ways is to selectively hydrogenate CO2 to methanol, which can not only effectively reduce CO2 emissions, but also prepare other chemicals and fuels. This article outlines the major progress in methanol synthesis through direct hydrogenation of CO2. Including the challenges of thermodynamics, the research progress of conventional copper-based catalysts was discussed, including the structure of support and co-catalyst, the role of chemistry and electron promotion, etc.
