AbstractIn this work, a novel Z-scheme Bi5O7-delta I/CeO2-delta heterojunction photocatalyst was prepared by combining hydrothermal synthesis and thermal treatment methods. Oxygen vacancies were in situ generated on the surface of Bi5O7-delta I and CeO2-delta nanostructures. The existence of oxygen vacancies significantly improved the light absorption of CeO2-delta and inhibited the recombination of photogenerated carriers. Based on the photocatalytic activity, the as-prepared Bi5O7-delta I/CeO2-delta photocatalyst exhibited excellent photocatalytic NO removal performance under visible light irradiation. The results of the capture experiment and electron spin resonance (ESR) spectroscopy show that super oxygen radicals (O-2(-)) and hydroxyl radicals (OH) are the main active species in the overall photocatalytic reaction process. Density functional theory (DFT) calculations and ESR results demonstrate that a Z-scheme heterojunction is formed between Bi5O7-delta I and CeO2-delta. Compared with the traditional type-II heterojunction, the Z-scheme heterojunction exhibited more efficient charge separation and robust redox capacity in the photocatalytic reaction.
