Abstract

The effect of H₂O₂ desorption on the direct synthesis of H₂O₂ from H₂ and O₂ over Pd-TiO₂(B)/anatase and Pd-anatase has been investigated. The interaction between H₂O₂ and the support has been studied by isothermal microcalorimetry and molecular dynamics (MD) simulation. H₂O₂ desorption from TiO₂(B)/anatase is more facile due to the existence of TiO₂(B). The accelerated H₂O₂ desorption from the catalyst surface can effectively decrease the hydrogenation rate of H₂O₂ over Pd-TiO₂(B)/anatase, which results in a 57% increase in the selectivity of H₂O₂ synthesis.
