Gold-indium modified TiO2 nanocatalysts for photocatalytic CO2 reduction with H2 as reductant in a monolith photoreactor

- Gold and indium based TiO2 monolithic catalysts tested for CO2 reduction with H2.
- Monolith photoreactor showed efficient CO2 reduction to CO through RWGS reaction.
- CO production rate over Au-In/TiO2 was 76 times higher than un-doped TiO2 catalyst.
- Quantum efficiency in Au-In/TiO2 for CO was 0.79%, much higher than in literature.
