Investigation on the Origin of Vanadium Catalyzed Electron Transfer-Oxygen Transfer Reactions in Liquid Phase via in-situ Valence to Core (v

Electron transfer (ET) and oxygen transfer (OT) reactions often occurs in enzyme catalyzed biological reactions for C-H bond activation and C-C bond cleavage. To follow the track of these type of reaction is very challenging with the conventional spectroscopic techniques. Hence, in the proposed study we plan to investigate on the role of V containing polyoxometalate (also known as heteropolyacids) towards ET-OT reactions with the help of high energy resolution fluorescence detected X-ray absorption near edge spectra (HERFD-XANES) and X-ray emission spectroscopy (XES). Moreover, the role of ion-exchanged and supported polyoxometalate (POM) will also be investigated during this study. It is also unclear how the POM is re-oxidized in presence of oxidants such as molecular oxygen or hydrogen peroxide, which we would like to find out throughout the proposed experiments.A successful outcome will certianly help other researchers to understand complex reactions.
