Underpotential deposition of cadmium was applied for in situ determination of electroactive surface area (ESA) of CdSe nanoparticles deposited by successive ionic layer adsorption and reaction (SILAR) onto TiO2 nanotubes and porous ZnO films. The sensitized photocurrent on CdSe/TiO2 and CdSe/ZnO ele...
