Photocatalytic water splitting and CO2 reduction utilizing semiconductors and/or metal complexes have emerged as a forefront research field, with growing expectations for sustainable production of clean fuels (e.g., H2) and chemicals (e.g., hydrocarbons) through the harnessing of abundant solar light energy. In recent decades, the scientific community has witnessed rapid advancement in the field of photocatalytic water splitting, encompassing various aspects ranging from fundamental research focused on the development of photocatalyst materials and reaction systems, to the integration of these materials into devices and larger scale demonstrations under natural sunlight.
However, creating the ultimate photocatalyst materials capable of achieving practically high solar-to-hydrogen conversion efficiencies (higher than 5%) by effectively harnessing a wide range of solar light spectrum remains a challenge. While CO2 is commonly regarded as a waste byproduct and an atmospheric pollutant resulting from the combustion of fossil fuels, it is noteworthy that in nature, CO2 serves as the fundamental building block for chemical synthesis and energy storage. A variety of chemical fuels and chemicals can also be derived via photocatalytic CO2 reduction. Significant advances have also been made in this research field, particularly focusing on metal complex photocatalysts, over the past few decades toward improving key catalyst parameters, including product selectivity, reaction rate and energetic efficiency. Innovative approaches, such as the utilization of super-molecules and hybrid systems involving semiconductors, have paved the way for advancing CO2 utilization. However, several challenges still remain, such as utilization of water as an electron source and diversifying the range of products beyond the two-electron reduction products of CO and HCOOH. We welcome manuscripts that address these challenges to the collection.
