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.
