Direct Conversion of CO2 to Multi‐Layer Graphene using Cu–Pd Alloys

A straightforward one‐step process was developed, in which CO2 gas is directly converted into multi‐layer graphene via atmospheric pressure chemical vapor deposition (APCVD). A bimetallic alloy film based on Cu and Pd was employed as the catalyst and substrate. In this study, we found that the quantity of Cu required for the CO2 conversion process is high (>82 at %). The findings gained in this study serve as a foundation for further studies of metallic alloys for the thermo‐reduction of CO2 to graphene under CVD conditions. Green graphene: Herein we report the direct conversion of CO2 gas to graphene. We achieve this one‐step process through a combination of the reductive power of hydrogen and the catalytic properties of a Cu–Pd alloy.
