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.
