A novel photoanode based on Thorium oxide (ThO2) incorporated with graphitic Carbon nitride (g-C3N4) for Photoelectrochemical water splitting
In this study, a new insight into the doping engineering with nuclear fuel (ThO2) was performed and applied in photoelectrochemical (PEC) water splitting. The successfully synthesized g-C3N4/ThO2 (-5.8%) via thermal treatment and g-C3N4 polymerization (precursor: Urea, 30 min; 520 C) manifested a re...

In this study, a new insight into the doping engineering with nuclear fuel (ThO2) was performed and applied in photoelectrochemical (PEC) water splitting. The successfully synthesized g-C3N4/ThO2 (-5.8%) via thermal treatment and g-C3N4 polymerization (precursor: Urea, 30 min; 520 C) manifested a remarkable and superior photocatalytic activity. The photocurrent density achieved for g-C3N4/ThO2 was 9.71 mu cm(-2) at 1.23 V vs. Ag/ AgCl under simulated light (100 mW/cm(2)) that is more than twice compared with the un-doped g-C3N4 (-4.23 mu A cm(-2)). The introduction of Thorium Nitrate during g-C3N4 polymerization altered the chemical bonding, structure, and morphology, with the improved PEC stability of the photoanode. Besides, doping with ThO2 increased the intensity of triazine and C-N bond in the g-C3N4 network, as observed by FT-IR analysis.
