Enhanced photocatalytic H2O2 production over Pt(II) deposited boron containing metal-organic framework via suppressing the simultaneous decomposition

Photocatalytic H2O2 evolution has received extensive attention as an environmentally friendly method, which is a dynamic process of formation and decomposition. At present, researches mainly focus on the formation, while decomposition rarely studied. In addition, platinum cocatalyst plays important role in enhancing photocatalytic activity, but effects valence state especially towards decomposition, not been studied detail to best our knowledge. this work, with different were deposited onto boron containing metal organic frameworks (UiO-67-B), roles Pt(0), Pt(II) Pt(IV) explored detail. Both experimental results theoretical calculations indicate that presence only promoting also inhibiting
