摘要
将CO_(2)转化为高附加值的产品既能减轻CO_(2)的排放压力,又能实现碳资源循环利用,其中CO_(2)加氢合成乙醇是一条有前景的路线。但由于CO_(2)的化学惰性和加氢过程涉及到后续的碳链生长步骤,通过CO_(2)加氢直接合成乙醇面临巨大挑战。综述了CO_(2)加氢制乙醇反应机理的研究进展,讨论了活性组分、载体、金属掺杂/负载以及工艺参数对催化剂性能的影响,并对未来的研究方向进行了展望。
Converting CO_(2)into high value-added products can not only reduce the pressure of CO_(2)emissions, but also realize the recycling of carbon resources. Among them, CO_(2)hydrogenation to ethanol is a promising route. However, due to the chemical inertness of CO_(2)and the subsequent carbon chain growth steps involved in the hydrogenation process, the direct synthesis of ethanol through CO_(2)hydrogenation faces great challenges. The research progress of reaction mechanism of CO_(2)hydrogenation to ethanol was reviewed, the effects of active components, supports, metal doping/loading and process parameters on the performance of catalysts,and the future research direction was prospected.
