“…[65][66][67][68][69][70][71][72][73] However, the energy at the 1/2-height of the edge is better, and indicates something close to Mo(VI), since Mo(IV) ½-height energies are typically below 20011 eV when using our chosen energy calibration. 63,64 With such uncertainty, it is not really possible to determine how much Mo(V) is mixed in; we therefore report here that the Mo K-edge XANES are consistent with a Mo(V,VI) state.…”
