Researchers have made a significant stride in the production of hydrogen peroxide (H2O2) with the introduction of a groundbreaking photocatalyst. The team from Jiangnan University and Tsinghua University have developed a self-assembled tetrakis(4-carboxyphenyl)porphyrin supramolecule (TCPP) that enables the reliable and sustainable production of H2O2 from water and oxygen through photocatalysis.
Unlike previous attempts, this new catalyst exhibits high solar-to-chemical conversion efficiency of approximately 1.2% and responds effectively to sunlight. The breakthrough paves the way for the development of organic photocatalysts with even greater solar efficiencies, promising a revolution in large-scale H2O2 production without the need for sacrificial reagents.
