“…However, this method still has several limitations: the synthesis process can only be carried out on a small/limited scale; a complex process for waste treatment is required; inhomogeneous energy distribution; it is difficult to control the temperature; the flammable organic solvent has limited uses; and the heat generated from irradiation cannot effectively penetrate the container reactor, so in some cases, the synthesis is considerably less efficient [179]. Therefore, Hao et al (2021) developed the combined microwave-hydrothermal synthesis route for producing Co/CoAl 2 O 4 /sepiolite nanocomposites [180]. The material was prepared under alkaline conditions of 1 mol/L NaOH at 240 • C for 3 h, followed by reduction at 650 • C. The composite materials could easily be obtained by these methods with a high efficiency as a cobalt-based catalyst.…”

Advanced oxidation processes (AOPs) utilizing heterogeneous catalysts have attracted great attention in the last decade. The use of solid catalysts, including metal and metal oxide nanoparticle support materials, exhibited better performance compared with the use of homogeneous catalysts, which is mainly related to their stability in hostile environments and recyclability and reusability. Various solid supports have been reported to enhance the performance of metal and metal oxide catalysts for AOPs; undoubtedly, the utilization of clay as a support is the priority under consideration and has received intensive interest. This review provides up-to-date progress on the synthesis, features, and future perspectives of clay-supported metal and metal oxide for AOPs. The methods and characteristics of metal and metal oxide incorporated into the clay structure are strongly influenced by various factors in the synthesis, including the kind of clay mineral. In addition, the benefits of nanomaterials from a green chemistry perspective are key aspects for their further considerations in various applications. Special emphasis is given to the basic schemes for clay modifications and role of clay supports for the enhanced mechanism of AOPs. The scaling-up issue is suggested for being studied to further applications at industrial scale.

“…(Xu et al, 2010;Zhu et al, 2012;Daneshkhah et al, 2017;Xu et al, 2019;. In our pervious study, we have prepared CoAl 2 O 4 /sepiolite nanofibers composite and Co./ CoAl 2 O 4 /sepiolite nanocomposite via different methods (Zhang et al, 2018;Wang F. et al, 2019;Hao et al, 2021;Wang et al, 2021). Nevertheless, as far as we know, there were few reports on sepiolite loaded ZnFe 2 O 4 as a catalyst.…”

The excellent photo-response of ZnFe2O4 in the visible light region makes it a promising catalyst, whereas some defects like serious particle agglomeration and easy recombination of photo-generated electron-hole pairs hinder its application. In this work, the ZnFe2O4/sepiolite (ZF-Sep) composites were synthesized using a co-precipitation method. The obtained ZF-Sep composites were characterized by XRD, SEM, TEM, FT-IR, XPS, BET, VSM and DRS. Moreover, the photocatalytic performance was evaluated by the tetracycline hydrochloride removal efficiency under simulated visible light illumination. The results displayed that the ZnFe2O4 with average sizes about 20 nm were highly dispersed on sepiolite nanofibers. All the composites exhibited better photocatalytic performance than pure ZnFe2O4 due to the synergistic effect of the improvement on the agglomeration phenomenon of ZnFe2O4 and the reduction on the recombination rate of photo-generated electrons and holes. The optimum removal efficiency was that of the ZF-Sep-11 composite, which reached 93.6% within 3 h. Besides, the composite exhibited an excellent stability and reusability. Therefore, ZF-Sep composite is a promising catalyst for the treatment of wastewater contained antibiotics.
