“…Figure 3 shows the FTIR spectra of samples GO, ZnO, Fe 2 O 3 , GO/ ZO/FO/ZFO1, GO/ZO/FO/ZFO2, GO/ZO/FO/ZFO3, and GO/ZO/FO/ZFO4. For all samples, the peaks at 3453 and 1616 cm −1 can be ascribed to the absorbed water due to the use of KBr in the tablet pressing process (Gao et al, 2021;Li et al, 2021;Liu et al, 2022). For the sample GO, the peaks at 1731 and 1065 cm −1 can be assigned to the graphene oxide (Dat et al, 2022;Hwa et al, 2022).…”

ZnO (ZO), Fe2O3 (FO), and graphene oxide (GO)/ZO/FO/ZnFe2O4 (ZFO) composite photocatalysts have been synthesized successfully via a simple sol–gel method and low-temperature technology. The phase structure and microstructural analysis confirmed that the GO/ZO/FO/ZFO magnetic separation photocatalyst is composed of GO, hexagonal ZnO, rhombohedral Fe2O3, and spinel ZnFe2O4 without any other impurities. The GO/ZO/FO/ZFO composite photocatalysts have a high visible light optical absorption coefficient and photocatalytic activity for degrading dyes, refractory pollutants, and antibiotics. The degradation percentages of methyl orange, tetrabromobisphenol A, and oxytetracycline hydrochloride by the GO/ZO/FO/ZFO magnetic separation photocatalyst were 98% for 180 min, 99% for 150 min, and 85% for 180 min, respectively. The special synthesis path leads to the formation of a special heterojunction between GO, ZnO, Fe2O3, and ZnFe2O4, which does not change the optical band gap value of the main lattice Fe2O3, and enhances the surface defects of the GO/ZO/FO/ZFO magnetic separation photocatalyst, resulting in high charge carrier transfer and separation efficiency of the catalyst and then enhanced the photocatalytic activity of the GO/ZO/FO/ZFO magnetic separation photocatalyst.

“…Antibiotics, which are widely used in animal husbandry and medical therapy, can also cause serious environmental pollution. Various wastewater treatment technologies, such as adsorption, membrane filtration and coagulation/flocculation, [1][2][3][4] have been developed to eliminate toxic pollutants from wastewater. However, these traditional wastewater treatment technologies generally require high energy consumption and costs and cannot transform toxic pollutants into harmless substances.…”

Photocatalysis is regarded as a green technology to degrade organic dyes driven by light energy. The selection of photocatalyst restricts the development of photocatalytic technology. Aluminate is a kind of potential broad-gap semiconductor photocatalyst and also an excellent phosphor substrate materials. The physical and chemical properties of aluminate are strongly dependent on the preparation method. Insight into the influence of synthesis methods on photocatalytic activity of aluminate based photocatalysts is helpful for the development of novel aluminate based photocatalysts. In this paper, the typical synthesis methods of aluminate photocatalysts, ion-doped aluminate based photocatalysts and heterojunction type aluminate photocatalysts, and their photocatalytic activities are reviewed. Based on the energy band theory, the photocatalytic mechanisms of single component aluminate photocatalyst, ion-doped aluminate based photocatalyst, and heterojunction type aluminate photocatalyst were reviewed. The future development of aluminate based photocatalyst will give priority to the salinization of aluminate modified by silver and other metal particles and the photocatalytic application of activated ion modified aluminate based phosphors.
