Red phosphor/g-C3N4 heterojunction with enhanced photocatalytic activities for solar fuels production

- Metal-free photocatalyst is made by coupling red phosphor with carbon nitride.
- The r-P/g-C3N4 heterojunction leads to effective charge separation.
- Photocatalytic H2 evolution is remarkably enhanced by the r-P/g-C3N4 hybrid.
- The r-P/g-C3N4 hybrid is more active for photocatalytic CO2 conversion into CH4.
