Comparative Studies of Oxygen‐Free Semiconductors in Photocatalytic CO2 Reduction and Alcohol Degradation
Commercially available α‐SiC, β‐SiC, GaN, ZnTe and self‐synthesized g‐C3N4 were investigated in a comparative study regarding their photocatalytic capabilities in CO2 reduction and alcohol degradation. Under reproducible high‐purity solid‐gas conditions none of the tested materials promoted CO2 reduction using H2O as proton donor, although TiO2 P25 has been shown to produce significant amounts of CH4 under similar conditions. Replacing H2O with 2‐propanol led to hydrocarbon formation which could solely be attributed to alcohol degradation while no CO2 reduction took place.
