Abstract
Polymeric-C3N4 is a photocatalyst with desirable properties for efficient solar fuel (H2) generation. However, p- C3N4 exhibits a low H2 evolution rate. Herein, InVO4 is successfully incorporated on the surface of p- C3N4 nanosheets via a one-pot solvothermal method to generate solar fuel (H2) effectively. The optical gap energy of p- C3N4 was red-shifted to 2.23 eV after incorporating InVO4. A small arc radius of the Nyquist plot and substantial quenching of PL was observed when InVO4 was added to p- C3N4. The optimized catalyst loading (15 wt%) shows a maximum H2 production activity of 8980 µmol/g/h. This outstanding performance is a nearly 56-fold enhancement in comparison with bare p-C3N4. Furthermore, the STH conversion efficiency of 1.87% is achieved with the optimized photocatalysts, which is higher than many g- C3N4 - based photocatalysts. Moreover, the H2 generation activity achieved in the present work is higher than the reported one using the same InVO4-g- C3N4 photocatalysts.
