A perspective with an explicit account of the appropriate screening water splitting electrocatalysts advocating dos and don’ts!

Abstract Spontaneous noble metal dopant segregation in an oxide lattice can lead to the formation of metallic clusters and extended acicular inclusions. In a thin-film process, shape orientation such inclusions are governed by crystal growth direction, giving rise composite material with lattice-matched nanopillars embedded vertically insulating or semiconducting matrix. An interesting applicat...

Recent experimental findings suggest that strontium titanate SrTiO3 (STO) photocatalytic activity for water splitting could be improved by creating multifaceted nanoparticles. To understand the underlying mechanisms and energetics, model faceted nanoparticles was created. The nanoparticles’ surface is considered us as a combination of flat “stepped” facets. Ab initio calculations adsorption oxy...
