A review of recent development on catalysts for direct synthesis of hydrogen peroxide from hydrogen and oxygen

Hydrogen peroxide (H₂O₂) is a green oxidant with high efficiency (above 47.1% active oxygen), and is widely used in the production of fine chemicals, bleaching of textile and pulp, treatment of wastewater, and green chemical synthesis metallurgy. Recently, the direct synthesis of H₂O₂ (DSHP) from H₂ and O₂ has attracted great attention because of its environmentally friendly process and simple, atom-efficient route. In this paper, the catalytic mechanism for DSHP and the influence of catalytic performance for different structures and properties of different metals in recent years are summarized. The support acid sites, support structure, the interaction between active sites and acid sites are discussed. Finally, the catalytic performance of catalysts for DSHP in recent years are compared. It reveals that the industrial application of catalysts for DSHP with high selectivity and high productivity in the future is still the development direction.
