“…However, the preparation of piezoelectric catalysts based on ultra-thin nanosheets is still challenging. 9–11 In addition, traditional piezoelectric materials such as PbTiO 3 , 12 KNbO 3 , 13 BiFeO 3 , 14 Bi 2 WO 6 15 and BaTiO 3 16 have limitations such as low specific surface areas, weak piezoelectric potential and insufficient catalytic active sites. Therefore, in order to improve the piezoelectric catalytic efficiency, 17–19 it is urgent to find catalysts with high piezoelectric coefficients, large specific surface areas and high surface atomic ratios.…”

“…A variety of strategies, including element doping and heterojunction construction, have been developed to solve these problems [14][15][16][17][18][19][20][21][22]. Among these strategies, the construction of a heterojunction is a research hotspot [23]. For example, a variety of heterojunction photocatalysts [16], including type I [24], type II [25], Z-scheme [26,27], and S-scheme [10] heterojunctions, have been extensively studied with regard to the visible-light degradation of TCH.…”

The development of photocatalysts with a wide spectral response and effective carrier separation capability is essential for the green degradation of tetracycline hydrochloride. In this study, a magnetic recyclable Z-scheme ZnO/ZnFe2O4 heterojunction (ZZF) was successfully constructed via the solid phase method, using MIL-88A(Fe)@Zn as the precursor. An appropriate band gap width and Z-scheme charge transfer mechanism provide ZZF with excellent visible light absorption performance, efficient charge separation, and a strong redox ability. Under visible light irradiation, the degradation efficiency of tetracycline hydrochloride for the optimal sample can reach 86.3% within 75 min in deionized water and 92.9% within 60 min in tap water, exhibiting superior stability and reusability after five cycles. Moreover, the catalyst in the water can be conveniently recovered by magnetic force. After visible light irradiation for 70 min, the temperature of the reaction system increased by 21.9 °C. Its degradation constant (35.53 × 10−3 min−1) increased to 5.1 times that at room temperature (6.95 × 10−3 min−1). Using thermal energy enhances the kinetic driving force of the reactants and facilitates carrier migration, meaning that more charge is available for the production of •O2− and •OH. This study provides a potential candidate for the efficient degradation of tetracycline hydrochloride by combining thermal catalysis with a photocatalytic heterojunction.
