“…Architecting heterojunctions is one of the most popular strategies to addressing this issue. Nowadays, various BiOBr-based heterojunctions have been architected with other semiconductor materials to inhibit e – –h + pair recombination and achieve high-efficiency photodegradation of organic pollutants, including S-scheme (BaFe 12 O 19 /BiOBr and P-doped g-C 3 N 4 /BiOBr), Z-scheme (Cu 2 ZnSnS 4 /BiOBr), type-II (BiOBr@ZnIn 2 S 4 and BiOBr/Bi 3 O 4 Br), and p-n (BiOBr/α-Bi 2 O 3 and BiOBr/ZnO) heterojunctions. In a heterojunction, the mismatched Fermi levels of the distinct semiconductors can promote spatial separation of the photogenerated e – –h + pairs at their contact interfaces.…”

It is a challenging task to design a piezoelectric photocatalyst with excellent performance under mechanical agitation instead of ultrasonic irradiation. Integrating vacancy defects into a heterojunction seems to be an effective strategy for synergistically increasing its piezo-photocatalytic performance. For this goal, a two-step hydrothermal method was adopted to architect a type-I oxygen-vacancy-rich BaTiO3/BiOBr heterojunction to surge the degradation of Rhodamine B (RhB) under the combined action of simulated sunlight irradiation and mechanical agitation. Various instrumental techniques demonstrated the formation of a BaTiO3/BiOBr heterojunction with high crystallinity. The existence of surface oxygen vacancies was confirmed by XPS and EPR tests. PFM results manifested that this heterojunction had excellent piezoelectric properties, with a piezoelectric response value of 30.31 pm V–1. Comparative experiments indicated that RhB degradation efficiency under piezo-photocatalysis over this heterojunction largely exceeded the total sum of those under piezocatalysis and photocatalysis. h+, ·O2 –, and 1O2 were the dominant reactive species for RhB degradation. The improved separation efficiency of photogenerated charges was verified by electrochemical measurements. DFT calculations indicated that the polarization of BaTiO3 could affect the electronic band structure of BiOBr. This work will provide comprehensive insights into piezo-photocatalytic mechanism at a microcosmic level and help to develop new-styled piezoelectric photocatalysts.

A variety of unique compounds have been examined to accommodate the current demand for useful multi‐functional nanomaterials, copper‐based quaternary CZTS semiconductors are one of them. Due to their special characteristic features like non‐toxicity, cheap, and abundance, they have been recommended in recent literature for various applications. Apart from individual CZTS, different hetero‐structures have also been prepared with different compounds which is well discussed and elaborated in this article. Additionally, their preparation methods, properties, and application viability have also been discussed comprehensively. The application of CZTS such as photocatalytic dye degradation and hydrogen evolution reaction has been elaborated on in this article identifying their benefits and challenges to give readers a thorough visualization. Apart from that, challenges reported in studies, a few approaches are also mentioned to possibly counter them.
