Abstract
- The performance of photocatalytic fuel cell (PFC) is mainly determined by photoanode. In order to reduce the recombination rate of electron–hole pairs and extend the light response wavelength, g-C<subscript>3</subscript>N<subscript>4</subscript>/WO<subscript>3</subscript>/TiO<subscript>2</subscript>/Ti photoanode was successfully fabricated by mixed sol–gel dipping method. Its maximum photocurrent density is 2.27 mA·cm<superscript>−2</superscript> at 1.1 V (vs. SCE), which is 1.64 and 1.57 times that of WO<subscript>3</subscript>/TiO<subscript>2</subscript>/Ti and g-C<subscript>3</subscript>N<subscript>4</subscript>/TiO<subscript>2</subscript>/Ti, respectively. The maximum power density, short circuit current density, and RhB degradation efficiency of PFC with g-C<subscript>3</subscript>N<subscript>4</subscript>/WO<subscript>3</subscript>/TiO<subscript>2</subscript>/Ti-Cu photoanode and Cu cathode are 19.35 μW·cm<superscript>−2</superscript>, 0.20 mA·cm<superscript>−2</superscript>, and 87.7%, respectively. The excellent performance of PFC is mainly attributed to the fact that TiO<subscript>2</subscript>/Ti is co-doped with g-C<subscript>3</subscript>N<subscript>4</subscript> and WO<subscript>3</subscript>, which greatly expands its light absorption range, strengthen its light absorption intensity, and improves its carrier mobility.
