Fig. 3: Theoretical study of water dissociation.
From: Pt nanoclusters on GaN nanowires for solar-asssisted seawater hydrogen evolution
The Pt/GaN interface promotes water splitting. Optimized structures and calculated energy changes of a water dissociation on Pt(111), b proton transfer from surface N–H to a Pt cluster, c water dissociation at a Pt-Ga site at the Pt/GaN interface and subsequent H spillover to Pt surface. All energy changes are in the unit of eV. The white, red, blue, green, and gray spheres represent H, O, N, Ga, and Pt atoms, respectively.
