Consequences of substituting framework metals in polyoxometalates on H-atom uptake: proton-coupled electron transfer at a Keggin-type polyoxomolybdate
The proton-coupled electron transfer to the surface of a Keggin-type polyoxomolybdate, [<sup><i>n</i></sup>Bu<sub>4</sub>N]<sub>3</sub>[PMo<sub>12</sub>O<sub>40</sub>], is described. The thermochemistry of surface O-H bonds generated upon reduction/protonation of the assembly is determined (∼67 kcal mol<sup>-1</sup>). Kinetic investigations provide evidence that proton-electron pairs are added to the polyoxomolybdate surface through a concerted mechanism.
