Finally, it should be noted that fatty alcohols are readily available from vegetable waxes and as pulping sub-products, and the products of their partial oxidation represent a valuable feedstock for the synthesis of pharmaceuticals and cosmetic products. Our work thus not only showcases a rational design of a robust photocatalyst for H2O2 production under biphasic conditions that enables an easy separation of the product from electron donors and its recovery at very high concentrations, but also paves the way for sustainable and economically viable light-driven H2O2 production from easily available feedstock.
