Visible Light-Responsive AlFeO3@g-C3N4 Heterojunction for Efficient Degradation of Organic Wastewater
Abstract
A Z-type AlFeO3@g-C3N4 photocatalyst was successfully prepared via sol-gel and high-temperature polymerization. The morphology, structure, and composition of the catalysts were analyzed by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The photocatalytic performance was evaluated by nitrobenzene degradation experiments and electrochemical station, comparing with single g-C3N4 and AlFeO3. Optimizing AlFeO3 precursor content in the composite yielded 1.6 and 1.8-fold higher degradation rates than single g-C3N4 and AlFeO3, respectively. Furthermore, in comparison to other ratios of AlFeO3@g-C3N4 composites, AF-CN-100, which exhibited the best degrading performance, had the smallest impedance, the strongest transient photocurrent response strength, and the strongest redox capacity. The heterojunction produced between AlFeO3 and g-C3N4 was a Z-type heterojunction, as revealed by investigations on energy band structure and mechanism. This heterojunction substantially improved the separation efficiency of photogenerated electrons and holes and increased the photocatalytic activity of the composites.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
