“…S3). The degradation of parent CQP ( m / z = 320.19) mainly proceeded from the substituents of the side chain, in which there are two primary pathways for CQP degradation [ 50 , 51 ]. Specifically, under the action of active species (·O 2 − and ·OH), CQP could first disconnect the carbon nitrogen bond on the side chain to form B ( m / z : 179.04), C ( m / z : 181.03) and D ( m / z : 124.04), respectively.…”

With the continuous spread of COVID-19, the water pollution problems caused by the abuse of chloroquine phosphate (CQP) as an antiviral drug have attracted wide attention. The cubic Fm-3m spinel high entropy oxide (HEO)—(MgCuMnCoFe)O x was prepared by coprecipitation method as the catalytic wet air oxidation (CWAO) catalyst to treat CQP simulated wastewater. Through electron spin resonance (ESR) analysis, HEO will stimulate the production of superoxide radical (·O 2 − ) and hydroxyl radical (·OH) in the wet air oxidation (WAO) process, which accelerates the degradation and mineralization of CQP. Through response surface method (RSM) optimization, the optimal degradation conditions of CQP in CWAO were proposed: initial oxygen pressure of 15 bar, catalyst dosage of 1.4 g/L and temperature of 230 °C. The advantages of HEO in CWAO were analyzed by principal component analysis (PCA). The degradation mechanism of CQP in CWAO by (MgCuMnCoFe)O x were explored. This work provides a new idea for the rapid development of HEO in the field of environmental catalysis.

“…For the H10Z8 composite, both the typical peaks of HNTs and ZIF-67 could be found. Meanwhile, the typical peaks at 1440 and 1308 cm –1 are observed, which are ascribed to the stretching vibration of the C–C or C–O and C–O group, respectively, of fumarate in MIL-88A, and the peak at 561 cm –1 is assigned to the Fe–O stretching vibration . It is not difficult to find that these characteristic peaks of MIL-88A and HNTs could be also discovered in the FTIR spectrum of the H1M27 sample.…”

Metal–organic frameworks (MOFs) have received great attention in environmental remediation application. In particular, one-dimensional (1D) MOF materials have excellent catalytic degradation performance because of their extraordinary surface–volume relationship, unique interface and surface structure characteristics, and high surface area. Nevertheless, an effective, simple, and environment friendly method to fabricate 1D MOF materials is very important for their large-scale application, especially in environmental treatment with strict cost requirements. Herein, two kinds of 1D MOF composites (HNTs/ZIF-67 and HNTs/MIL-88A) could be fabricated controllably by using natural halloysite nanotube (HNT) minerals via in situ growth induced by electrostatic adsorption. The typical morphological characteristic of HNTs/ZIF-67 is its mulberry shape with ZIF-67 nanoparticles being grown on the surface of HNTs, while HNTs/MIL-88A is rice-shaped in which the introduced HNTs affect the growth size of HNTs/MIL-88A remarkably. Furthermore, the solar-Fenton catalytic performances and mechanisms of the HNTs/ZIF-67 and HNTs/MIL-88A composites are investigated. The results indicate that the HNTs/ZIF-67 and HNTs/MIL-88A composites could remarkably degrade methylene blue in peroxymonosulfate (PMS) and H2O2 systems under solar light, respectively. The active species capture experimental data, and electron paramagnetic resonance determinations reveal that HNTs/ZIF-67 in the PMS system could be excited to mainly generate SO4 –• radicals and HNTs/MIL-88A in the H2O2 system could be excited to mainly generate •OH radicals. This work provides a simple and effective strategy to construct high-efficiency 1D MOF catalysts based on cheap, easily available, and eco-friendly HNT materials. It would also greatly promote the low-cost and large-scale application of MOF materials in environmental treatment.

Advanced oxidation technology of persulfate is a new method to degrade wastewater. As the economy progresses and technology develops, increasingly more pollutants produced by the paper industry, printing and dyeing, and the chemical industry are discharged into water, causing irreversible damage to water. Methods and research directions of activation persulfate for wastewater degradation by a variety of iron-based catalysts are reviewed. This review describes the merits and demerits of advanced oxidation techniques for activated persulfate by iron-based catalysts. In order to promote the development of related research work, the problems existing in the current application are analyzed.
