“…The morphology of composite shows the shaped structure thin flakes. This morphology closed to reports by Gholami et al (2019) that the integration of Zn-Co-LDH with BC resulted in the formation of a regular-shaped[26]. The particle size was calculated by ImageJ application as shown inFig.…”

In this work, CuAl/Biochar (BC) composite was prepared by the coprecipitation method. The materials were applied to remove malachite green in aqueous solution. These materials were characterized using XRD, FTIR, BET and SEM-EDX analyses. The composite material was confirmed by X-ray diffractograms with reflection (002) at 24o and the appearance of new peaks at 1095 cm -1 . The BET result of CuAl/BC composite has larger surface area is 168 m 2 /g than 46 m 2 /g for LDH. The morphologies of composite materials show agglomeration and micro particle size. The result of the adsorption study indicated the composite material follows pseudo-second-order (PSO) and Langmuir isotherm models. The maximum adsorption capacity of malachite green using CuAl/BC uptake is 164.316 mg/g. The thermodynamic analysis indicates that the malachite green adsorption is spontaneous, endothermic. Regeneration study of adsorbent CuAl/BC composite shows after four times reused, it still has high removal efficiency at 89%.

“…3a demonstrates the results of studying the pseudo-first-order decay of SFL (k app , min -1 ) in the presence of different processes such as adsorption, photocatalytic degradation, UVlight activated persulfate, and finally photocatalytic activation of the PS. Taking consideration of the obtained results, all the studied processes showed the correlation coefficient (R 2 ) values more than 0.9, indicating that all the systems followed pseudo-firstorder kinetics which accords with the literature [21,46]. Considering Fig.…”

Hence, for the better interpretation, the synergy factor for PS/catalyst, UVA/catalyst, UVA/PS, and UVA/catalyst/PS processes was calculated by using the previously reported equations [46]. Accordingly, the synergy factor was found to be 1.1, 2, and 2.08 for PS/catalyst, UVA/catalyst, and UVA/PS processes.…”

In this work, the cubic cobalt and zinc doped and co-doped magnetite nanocatalysts were synthesized and characterized using different analysis. The so-synthesized photocatalysts were used for the activation of hydrogen peroxide (HP) and persulfate (PS) under UVA irradiation. The integration of Fe 2.5 Co 0.3 Zn 0.2 O 4 improved the activation of PS and HP; wherein, the UVA/Fe 2.5 Co 0.3 Zn 0.2 O 4 /PS process demonstrated higher degradation performance for Sulfalene (SFL) as a veterinary pharmaceutical contaminant in water. Afterward, the effect of different physicochemical parameters was studied and the radicals generated through the process were identified using chemical scavengers. UVA/Fe 2.5 Co 0.3 Zn 0.2 O 4 /PS process brought about 67% of SFL degradation in real wastewater. Moreover, 85% of TOC removal was achieved within 15 h of the abovementioned process. Eventually, the phototoxicity of the untreated and treated SFL solution after 120 min of the UVA/Fe 2.5 Co 0.3 Zn 0.2 O 4 /PS process was studied using Lemna minor aquatic species.

“…However, the excessive usage of TCH has created many critical problems, leading to TCH being considered as an influential pollutant (Heidari et al, 2018). To date, many efforts like adsorption, coagulation, chemical oxidation, deposition, membrane separation, biological, physicochemical, and electrochemical techniques have been utilized to remove these dyes and antibiotics, with a particular focus on MB and TCH (Zhang et al, 2018;Gholami et al, 2019Gholami et al, , 2020Huo et al, 2019b;Kohtani et al, 2019;Li et al, 2019c;Liu et al, 2019b;Wang et al, 2019a). However, long handling times, secondary pollutants and low efficiencies limits the usage of these techniques (Wang et al, 2014;Li et al, 2017Li et al, , 2018Karimi et al, 2019;Liu et al, 2019a;Qi et al, 2019b,c;Shen et al, 2019;Takeda et al, 2019).…”

Construction of 1D Ag-AgBr/AlOOH Plasmonic Photocatalyst for Degradation of Tetracycline Hydrochloride

In this work, the highly efficient and low-cost Ag-AgBr/AlOOH plasmonic photocatalyst is successfully prepared via a simple and mild wet-chemical process and used for degrading high concentration methylene blue (MB) and tetracycline hydrochloride (TCH). The optimized 6-Ag-AgBr/AlOOH sample showed a 79% decomposition of TCH in 2 h, which is almost two times higher than that of bare AgBr (37%). For degrading MB, the photocatalytic activity of 6-Ag-AgBr/AlOOH (decomposing 84% in 2 h) showed a large enhancement as compared to bare AgBr (only 57%). The TEM, HRTEM, XRD, DRS, and XPS characterization results confirm that Ag-AgBr is a composite catalyst formed by loading Ag nanoparticles onto AgBr surfaces and then loaded on to AlOOH. The possible mechanism proposed is that • O − 2 and • OH radicals produced under sun light are the main active species for degrading MB and TCH. It is hoped that this work will open a new gateway to the synthesis of highly efficient and low-cost Ag-AgBr/AlOOH plasmonic photocatalysts for degrading organic pollutants.
