Metal-based electrocatalytic conversion of CO2 to formic acid/formate
The rapid increasing of CO2 content in the atmosphere caused serious environmental concerns. To effectively alleviate the issue, it is of great significance to use electrocatalytic technology to convert CO2 into high value-added energy materials. In this minireview, we present recent progress in the development of metal-based electrocatalysts for the electrocatalysis of CO2 to formic acid/formate. Firstly, we briefly study the possible reaction pathways and mechanisms of electrochemical reductions of CO2. Secondly, the emerging development of different types of metal-based electrocatalysts (homogeneous catalysts and heterogeneous catalysts) as high-performance catalysts are reviewed for improving process efficiency and productivity. Based on the above discussion, we summarize the current challenges and the future research directions of metal-based materials for the electrocatalytic reduction of CO2.
