A mini-review of ferrites-based photocatalyst on application of hydrogen production

Frontiers in Energy 2021, Volume 15, Issue 3,   Pages 621-630 doi: 10.1007/s11708-021-0761-0

Abstract: Photocatalytic water splitting for hydrogen production is a promising strategy to produce renewable energy and decrease production cost. Spinel-ferrites are potential photocatalysts in photocatalytic reaction system due to their room temperature magnetization, the high thermal and chemical stability, narrow bandgap with broader visible light absorption, and proper conduction band energy level with strong oxidation activity for water or organic compounds. However, the fast recombination of the photoexcited electrons and holes is a critical drawback of ferrites. Therefore, the features of crystallinity, particle size, specific surface area, morphology, and band energy structure have been summarized and investigated to solve this issue. Moreover, composites construction with ferrites and the popular support of TiO2 or g-C3N4 are also summarized to illustrate the advanced improvement in photocatalytic hydrogen production. It has been shown that ferrites could induce the formation of metal ions impurity energy levels in TiO2, and the strong oxidation activity of ferrites could accelerate the oxidation reaction kinetics in both TiO2/ferrites and g-C3N4/ferrites systems. Furthermore, two representative reports of CaFe2O4/MgFe2O4 composite and ZnFe2O4/CdS composite are used to show the efficient heterojunction in a ferrite/ferrite composite and the ability of resistance to photo-corrosion, respectively.

All-inorganic TiO/CsAgBiBr composite as highly efficient photocatalyst under visible light irradiation

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 12,   Pages 1925-1936 doi: 10.1007/s11705-023-2344-6

Abstract: In recent years, limited photocatalysis efficiency and wide band gap have hindered the application of TiO2 in the field of photocatalysis. A leading star in photocatalysis has been revealed as lead-free Cs2AgBiBr6 double halide perovskite nanocrystals, owing to its strong visible light absorption and tunable band gap. In this work, this photocatalytic process was facilitated by a unique TiO2/Cs2AgBiBr6 composite, which was identified as an S-cheme heterojunction. TiO2/Cs2AgBiBr6 composite was investigated for its structure and photocatalytic behavior. The results showed that when the perovskite dosage is 40%, the photocatalytic rate of TiO2 could be boosted to 0.1369 min–1. This paper discusses and proposes the band gap matching, carrier separation, and photocatalytic mechanism of TiO2/Cs2AgBiBr6 composites, which will facilitate the generation of new ideas for improving TiO2’s photocatalytic performance.
