Abstract

Abstract: Electrochemistry is a promising method to recycle CO2 into useful carbon feedstock and for storing intermittent renewable energy. To date, Au and Ag nanoparticles are the most active catalysts for electrochemical conversion of CO2 to CO. However, agglomeration reduces the activity and the high cost slows widespread commercialization. Suitable support materials are thus needed to improve catalyst utilization. We explore carbon foam (CF) as a catalyst support. Compared with carbon black or graphene nanoplatelets, CF has higher surface area, larger pores, and more defects, resulting in improved uniformity of Ag nanoparticle distribution as well as higher activity and efficiency for CO2 conversion to CO. Abstract : Foaming for success : Carbon foam is explored as a silver catalyst support material for the electroreduction of CO2 to CO. Compared with other support materials such as commercially available graphene powder or carbon black, the carbon foam significantly improves the dispersion of silver nanoparticles on the surface, leading to improved CO2 reduction performance.
