Synthesis of N-TiO2/WO3 Photoelectrodes with Controlled Morphology using Ammonium Metatungstate and F127

N-TiO2/WO3 photoelectrodes were successfully fabricated by employing ammonium metatungstate (H8N6O24W6) as both a nitrogen source for N-doped TiO2 and a precursor for WO3 in TiO2/WO3 composites. Additionally, titanium butoxide (C16H36O4Ti) was used as a precursor for TiO2. The addition of F127 as a template agent was crucial in controlling the morphology of the photoelectrodes.
