Researchers in Kolkata have discovered a groundbreaking approach to synthesizing hydrogen peroxide (H2O2) using covalent organic frameworks (COFs) as efficient photocatalysts. Hydrogen peroxide is a vital chemical in various industries for disinfection, paper bleaching, and more. Traditional industrial production methods are energy-intensive, expensive, and generate hazardous by-products. The team at S. N. Bose National Centre for Basic Sciences has designed hydrazone-linked COFs with unique catalytic properties to facilitate the generation of H2O2 through photocatalysis. These COFs outperformed organic photocatalysts, yielding high H2O2 production rates even under sunlight exposure. By employing a water-benzyl alcohol solution, the COFs demonstrated the potential for continuous H2O2 production, a step towards scalable industrial applications. This innovation not only offers a sustainable and environmentally friendly alternative for H2O2 synthesis but also paves the way for technology transfer from laboratory research to industrial production, benefiting various sectors reliant on hydrogen peroxide.
