Hydrogen peroxide (H2O2) has many industrial uses, from water treatment and bleaching to chemical synthesis. Although the current process for producing it is highly efficient, it requires a large infrastructure. Work recently carried out in collaboration with an industrial partner, and published in ChemCatChem, demonstrates a method for the direct synthesis of H2O2 from hydrogen and oxygen, using a commercial titanium silicate called TS-1, as a support for Gold Palladium (AuPd) and Gold Palladium Platinum (AuPdPt) catalysts, a reaction that could be carried out in situ as the first step in a manufacturing process. It shows that the introduction of small concentrations of platinum into a supported AuPd/TS-1 catalyst can significantly enhance catalytic selectivity towards H2O2, improving overall yields and representing a promising system to explore the direct synthesis of H2O2.
