Hydrogen spill-over effect on Pt/WO 3 anode catalysts

The experimental evidence and mechanism of ‘hydrogen spill-over’ on Pt/WO 3 is reviewed and the application of this catalyst system for the evolution of hydrogen, anodic oxidation, hydrogenation and the anodic oxidation of small molecules and impure H 2 is discussed. It is suggested that further wor...

Summary:The experimental evidence and mechanism of ‘hydrogen spill-over’ on Pt/WO 3 is reviewed and the application of this catalyst system for the evolution of hydrogen, anodic oxidation, hydrogenation and the anodic oxidation of small molecules and impure H 2 is discussed. It is suggested that further work on preparation techniques to ensure the maximisation of Pt/WO 3 interfaces and other analogous systems should lead to even higher catalyst activity and applications.
