Reduction Of Co2

A series of Cu–TiO2-x has been reasonably designed and synthesized as efficient photocatalysts for the reduction of CO2 with H2O to CH4. It is found that the high activity may be contributed by the co-existence of surface oxygen vacancies and Cu(i) species on {001} facets of TiO2.
