The development of sunlight-driven water splitting or CO2 reduction systems with high efficiency, scalability, and cost-competitiveness is a central issue in the mass production of fuels and energy-rich chemicals. We designed and developed all-solid-state devices, that is, photocatalyst sheets for photocatalytic water splitting and CO2 reduction. These photocatalyst sheets produced hydrogen via overall water splitting with high efficiency or reduced CO2 into formate/acetate with high selectivity, setting new benchmarks in the field of photocatalytic solar fuel production. Moreover, the photocatalyst sheet design is well-suited to large-scale applications. Our study offers a novel and versatile strategy toward sustainable and practical solar fuel production.
