Abstract

In this research work, we successfully prepared the Z-scheme BiVO 4 /porous graphite carbon nitride (Pg-C 3 N 4 ) composite by hydrothermal process at 180 °C, which realized strong redox capability under visible light, which was proved by enhanced photocatalytic degradation of methylene blue solution. The k app of 60%BiVO 4 /Pg-C 3 N 4 was 0.05251 min −1 , which was 4.6 and 7.2 times higher than that of BiVO 4 (0.00938 min −1 ) and Pg-C 3 N 4 (0.00643 min −1 ), respectively. The separation of charge carriers was effectively promoted, which was revealed by photoluminescence (PL) spectra and transient photocurrent response. Eventually, possible mechanism was also proposed.
