Abstract

Electrophoretic deposition is a straightforward method for synthesizing high-quality photoanodes. We present a protocol for synthesizing a TiO2-modified boron-doped diamond photoanode (BDD/TiO2) via electrophoretic deposition, detailing the chemical and electrochemical treatments applied to the bare BDD electrode prior to use. We provide a step-by-step guide for performing photoelectrochemical characterization under both dark and light conditions and describe an optical technique for investigating band-gap energy. For complete details on the use and execution of this protocol, please refer to Quilumbaquin et al.1.
