The amalgamation of a wide optical band gap photocatalyst with visible-light-active CdO quantum dots (QDs) as sensitizers is one of the most efficient ways to improve photocatalytic performance under visible light irradiation.
The reaction pathway for visible light photocatalytic NO removal with Pt quantum dots/N-doped (BiO)2CO3 was revealed with in situ FT-IR and ESR spectroscopy.
pg-C3N4 prepared through in situ bubble template showed large surface area and low recombination rate of photoinduced electron–hole pairs, leading to enhanced visible-light photocatalytic activity for degrading pollutants and splitting water to H2.
