Disentangling interfacial energetics

Understanding interfacial charge transfer in water-splitting photoelectrodes is complicated by the delicate interplay between catalyst and light absorber. Now, an approach based on atomic force microscopy is exploited to measure the surface electrochemical potential of nanostructured catalyst-coated electrodes in operando.
