Abstract:

Electrocatalytic conversion of carbon dioxide (CO2) has attracted widespread attention. In this field, the development of precious metal-free, porous carbon-based electrocatalysts stands out being the research hot spot. First, the key parameters in terms of pore structure, surface chemistry as well as morphology of porous carbon-based electrocatalysts have been overviewed. Then, the methods to improve the porous carbon-based electrocatalysts activity are summarized. Subsequently, the nature and distribution of active centers of carbon-based electrocatalysts are discussed. In the following, the pathways to increase the density of active sites in porous carbon-based electrocatalysts are analyzed. Finally, based on the advances made in the research community in recent years, we made perspectives on the developing trend and challenges of porous carbon-based electrocatalysts for efficient CO2 electroreduction.

Key words: porous carbons, carbon-based catalysts, CO2 electroreduction, heteroatom doping
