ConspectusThe photocatalytic generation of hydrogen peroxide (H2O2) through the utilization only H2O, O2, and sunlight represents an energy-efficient ecofriendly innovation in pursuit a sustainable society. Despite significant efforts that have been directed toward development H2O2 via photocatalysis, solar-to-chemical conversion (SCC) efficiency has not yet reached levels required for large-scale practical applications. Consequently, there is urgent demand to develop design novel photocatalysts characterized by several key attributes: high catalytic activity, cost-effectiveness, good stability. However, traditional inorganic photocatalysts, such as TiO2, exhibited limited partly attributable potential decomposition caused metal cations. Recent research found organic highly promising candidates address these limitations. Organic materials offer remarkable advantages including narrow bandgap, adjustable band edge potentials, ability control surface configurations use active sites, rational structural units promote efficient charge separation transfer. In field without sacrificial reagents, widely studied, various strategies improve activity stability explored. These include construction donor–acceptor structures, conjugated incorporation heteroatoms, enhancement internal electric field, substitution functional groups.
