Titanium dioxide-reduced graphene oxide thin film for photoelectrochemical water splitting


Jumeri, F. A. and Lim, Hong Ngee and Zainal, Zulkarnain and Huang, Nay Ming and Pandikumar, Alagarsamy (2014) Titanium dioxide-reduced graphene oxide thin film for photoelectrochemical water splitting. In: TOCAT7, 1-6 June 2014, Kyoto, Japan. (pp. 1-7).


The incorporation of reduced graphene oxide (rGO) on a TiO2 surface had been demonstrated to be an effective method to enhance the photoelectrochemical performance. A TiO2–rGO thin film was fabricated by depositing TiO2 on ITO using an aerosol-assisted chemical vapor deposition method and GO dip-coating, followed by thermal reduction of the GO layer. The fabricated thin film was characterized using XRD and FESEM techniques. The photoelectrotrochemical performance of the TiO2–rGO thin film was investigated under the illumination of simulated solar light. The TiO2–rGO showed a higher photocurrent response (80.2 µA) than bare TiO2 (13.1 µA). This improved photoelectrochemical performance was due to the rGO, which increased the electron transport and thereby minimized the charge recombination process. The TiO2–rGO thin film showed good stability, even after being subjected to 1000 voltammetric cycles, and the rGO sheets remained adhered to the surface of the TiO2 thin film.
