Sol-Gel Electrophoretically Deposited TiO₂-Multiwalled Carbon Nanotube-SiO₂ Thin-Film Electrode with High Photoelectrochemical Activity.

ABSTRACT: Hydrogen production via water splitting has been extensively researched for its environmental friendliness, energy efficiency, and renewability. This study describes the development of TiO₂-multiwalled carbon nanotube (MWCNT)-SiO₂ composite thin-film electrodes via electrophoretic deposition (EPD) from a 2-propanol solution of MWCNTs including TiO₂ and SiO₂ gels. The TiO₂ and SiO₂ gels were prepared via the sol-gel method and by mixing in varying weight ratios to enhance the efficiency of photoelectrochemical water splitting. Dual sol-gel EPD incorporates MWCNTs with a C/TiO₂ molar ratio of ≥0.25 while varying the TiO₂/SiO₂ molar ratio from 5 to 14; the electronic conductivity is improved owi
