“…One should note that the double bonds and amides are easily attacked by h + to form small organic molecules with m / z = 365. Further dehydroxylation and ring opening by h + and • O 2 – resulted in a small molecule with m / z = 279, which was further oxidized to an intermediate with m / z = 255 after the electron rearrangement and ring-opening reaction . The undetectable products with m / z = 427 and 365 can be ascribed to the complete consumption during the reaction .…”

The development of efficient, stable, and visible-light-responsive photocatalysts is crucial to address the pollution of water bodies by toxic heavy metal ions and organic antibiotics. Herein, a series of LaNi1–x Fe x O3/g-C3N4 heterojunction photocatalysts are prepared by a simple wet chemical method. Moreover, LaNi0.8Fe0.2O3/g-C3N4 composites are characterized by various methods, including structure, morphology, optical, and electrochemical methods and tetracycline degradation and photocatalytic reduction of Cr(VI) under visible light irradiation. Then, the photocatalytic performance of as-prepared LaNi0.8Fe0.2O3/g-C3N4 composites is evaluated. Compared with pure LaNi0.8Fe0.2O3 and g-C3N4, the LaNi0.8Fe0.2O3/g-C3N4 composite photocatalysts exhibit excellent photocatalytic performance due to synergy of doping and constructing heterojunctions. The results show that the doping of Fe ions can increase the concentration of oxygen vacancies, which is ultimately beneficial to the formation of electron traps. Moreover, the type-II heterojunction formed between LaNi0.8Fe0.2O3 and g-C3N4 effectively strengthens the separation and transfer of photoinduced carriers, thereby promoting photocatalytic activity. Furthermore, the photocatalytic activity of the LaNi0.8Fe0.2O3/g-C3N4 photocatalyst remains almost unchanged after three cycles, indicating long-term stability. Ultimately, the photocatalytic mechanism of the LaNi0.8Fe0.2O3/g-C3N4 composites is proposed.

“…With the rapid development of industry, serious water pollution has been caused. Photocatalytic technology converts solar energy into green chemical energy and generates redox active substances that can remove pollutants. − Numerous photocatalysts have been used to remove different pollutants including colorful aromatic dyes, − colorless antibiotic pollutants, − pesticide residues, , and harmful metal ions − in wastewater at present. Cr(VI) is a common harmful heavy metal in wastewater due to its high solubility and toxicity and is classified as carcinogenic (class I). , Conventional methods to remove Cr(VI) cost a lot and have a risk of secondary pollution, whereas photocatalytic removal of Cr(VI) is believed to be a green and sustainable way to reduce energy consumption. , Although the development of photocatalyst research has achieved great progress, the low charge transfer efficiency remains a key limiting factor in the practical application of photocatalysts. , …”

Compound semiconductor photocatalysis technology is considered to be a promising treatment for solving water problems efficiently. The point of designing high-efficiency catalysts is to optimize the band gap structure and facilitate the separation of charge carriers by establishing new electron migration pathways. Recently, 3D porous CaIn2S4 was found to have good photocatalytic ability. However, the quick recombination and agglomeration of carriers still limit its application. Herein, we prepared a heterostructure by introducing 2D Sr-doped SnS2 to 3D CaIn2S4 by a hydrothermal synthesis method. The optimal dosage of Sr-SnS2 is 3%, and the photocatalytic Cr(VI) removal efficiency of 3% Sr-SnS2/CaIn2S4 (SSCS-3) is 5.82 and 10.83 times those of pure CaIn2S4 and SnS2, respectively. According to the results of characterization tests and calculation verification, we inferred that the enhanced photocatalytic removal of Cr(VI) is due to the introduction of Sr-SnS2 that can promote the rapid transfer of photogenerated electrons to the surface of CaIn2S4, and the heterostructure formed between 2D Sr-SnS2 and 3D CaIn2S4 can also provide abundant reaction sites. The promotion of carrier separation is mainly due to the formation of a built-in electric field of the Sr-SnS2/CaIn2S4 heterostructure. This work provides new ideas and technologies for the treatment of Cr(VI) in wastewater.
