Resolving the Mechanism for H₂O₂ Decomposition over Zr(IV)-Substituted Lindqvist Tungstate: Evidence of Singlet Oxygen Intermediacy.

ABSTRACT: The decomposition of hydrogen peroxide (H₂O₂) is the main undesired side reaction in catalytic oxidation processes of industrial interest that make use of H₂O₂ as a terminal oxidant, such as the epoxidation of alkenes. However, the mechanism responsible for this reaction is still poorly understood, thus hindering the development of design rules to maximize the efficiency of catalytic oxidations in terms of product selectivity and oxidant utilization efficiency. Here, we thoroughly investigated the H₂O₂ decomposition mechanism using a Zr-monosubstituted dimeric Lindqvist tungstate, (Bu₄N)₆[{W₅O₁₈Zr(μ-OH)}₂] ({ZrW₅}₂), whic
