  • In photoelectrochemical (PEC) cells, water oxidation to O2, when coupled to CO2 reduction, typically requires a pair of light absorbers or an applied bias voltage. Now, a bias-free PEC cell with a single sunlight absorber drives simultaneous CO2 reduction to give formate, and the oxidation of an organic substrate in aqueous conditions.

  • Immobilized molecular catalysts can be efficient for the electroreduction of CO2, but their practical applicability is hampered by the continued use of rare metals. Here, a photoelectrode based on an earth-abundant molecular catalyst with high CO2 reduction performance is introduced.

  • Semi-artificial photosynthetic systems combine natural and synthetic features to overcome limitations of each approach to produce solar fuels. Sokol et al. integrate a dye-sensitized TiO2 photoanode with the natural machineries, photosystem II and hydrogenase, to split water without additional applied bias.

  • Lead-halide perovskites are sensitive to humidity, which limits their use in water splitting applications. Here, the authors protect the perovskite layer with Field’s metal, driving photoelectrocatalytic hydrogen evolution in an aqueous solution for approximately one hour under constant illumination.

  • Selective photocatalytic conversion of CO2 into fuels without using sacrificial reagents and external bias has proved difficult. Addressing these challenges, Wang and colleagues fabricate wireless photocatalyst sheets comprising a molecular cobalt catalyst and metal oxide semiconductors that convert CO2 and H2O into formate and O2.

  • Metal–organic framework (MOF) materials are promising photocatalysts for solar-driven fuel production from CO2. Here, built on a literature survey and data macroanalysis, we examine the development of MOFs as photocatalysts for CO2 conversion, while assessing pitfalls and opportunities.

  • The light-driven conversion of abundant resources such as CO2 and H2O into chemical fuels for energy storage is crucial to end our dependence on fossil fuels. This Review highlights how molecular catalysts and photosensitizers can be grafted onto metal–organic frameworks to combine the advantages of both classes of compounds. Different synthetic strategies are discussed, along with their advantages and limitations.
