As one of the most effective methods, CO₂ hydrogenation through heterogeneous catalysis is a promising means to mitigating the detrimental effects of anthropogenic CO₂ that also accomplishes the effective recycling of carbon element. Considering the inertness of the CO₂ molecule as well as the subsequent low chain propagation activity, the products are usually small molecules such as methane, methanol and formic acid. Furthermore, the imprecise regulation of C–C coupling further hinders the acquisition of target products. These problems make CO₂ hydrogenation to useful C₂₊ hydrocarbons more challenging. Therefore, the rational design and fabrication of highly efficient and selective catalysts, including promoter-modified single metal catalysts, composite catalysts and bimetallic catalysts, is an inevitable process to upgrade the end products of CO₂ utilization. This review will focus on the recent developments in the highly selective formation of C₂₊ hydrocarbons, especially the utilization of composite catalysts or multi-functional catalysts, which indicate the great potential derived from the synergistic effect of multi-active sites.

二氧化碳直接催化加氢成有价值的C ₂₊烃的最新进展

作为最有效的方法之一，通过非均相催化进行的CO ₂加氢是减轻人为产生的CO ₂的有害作用的有前途的手段，该方法还可以实现碳元素的有效循环。考虑到CO ₂分子的惰性以及随后的低链传播活性，产物通常是小分子，例如甲烷，甲醇和甲酸。此外，CC耦合的不精确调节进一步阻碍了目标产物的获得。这些问题使CO ₂加氢成为有用的C ₂₊碳氢化合物更具挑战性。因此，合理设计和制造高效且选择性的催化剂，包括促进剂改性的单金属催化剂，复合催化剂和双金属催化剂，是提高最终CO ₂利用率的必然方法。这篇综述将集中在高选择性形成C ₂₊碳氢化合物的最新发展，特别是复合催化剂或多功能催化剂的利用上，这表明从多活性位点的协同效应中获得了巨大的潜力。
