The photocatalytic conversion of CO2 using H2O over heterogeneous photocatalysts has attracted worldwide attention because it enables direct solar‐to‐chemical energy conversion. However, further development of this technology requires solutions to overcome the low formation rates of CO2 reduction products and their insufficient selectivity, mainly caused by the rapid charge recombination of photogenerated electron/hole pairs, competition for thermodynamically preferential H2 evolution from H2O, and the relatively low concentration of CO2 on the surface of the photocatalysts. Surface modification of heterogeneous photocatalysts is crucial for improving their formation rates and selectivity. This review article introduces four strategies for designing photocatalyst surfaces for the photocatalytic conversion of CO2 by H2O: (I) loading of an Ag cocatalyst, (II) utilisation of cocatalysts for H2O oxidation, (III) suppression of undesired H2 evolution, and (IV) loading of basic materials for CO2 adsorption. The strategies introduced in this review successfully enhanced the formation rates of the products and/or their selectivity in the heterogeneous photocatalytic conversion of CO2 by H2O.
