二氧化碳排放量的持续增长已经造成了严重的环境问题。为了解决这一问题,利用催化剂催化CO2加氢制甲酸为减少温室效应和生产高附加值化学品和燃料提供了一种很有前途的方法。在众多研究中,负载型非均相催化剂（尤其是Pd基催化剂）被认为最具推广前景。本文概述了近10年来以Pd为主要活性组分的Pd基单金属和Pd基双金属非均相催化剂在CO2加氢制取甲酸方面的研究进展,总结了影响催化活性的因素,并为今后设计出更高甲酸选择性和高活性的Pd基非均相催化剂提供了思路。
The continuous growth in carbon dioxide emissions has caused serious environmental issues. To solve this problem, catalytic hydrogenation of CO2 to formic acid by efficient catalysts supplies a promising method to reduce the greenhouse effect and produce value-added chemicals and fuels. Among the many studies, supported heterogeneous catalysts (especially Pd-based catalysts) are considered to be the most promising. This paper summarizes the research progress of Pd-based heterogeneous and Pd-based bimetallic heterogeneous catalysts with Pd as the main active component in the production of formic acid by CO2 hydrogenation in the past 10 years, summarizes the factors affecting the catalytic activity, and provides ideas for the design of Pd-based heterogeneous catalysts with higher formic acid selectivity and high activity in the future.
