Ni(OH)2 surface-modified hierarchical ZnIn2S4 nanosheets: dual photocatalytic application and mechanistic insights

“…65-2023). 51 The diffraction peaks located at 19.7°, 33.3°, 38.4°, 59.4° and 62.7° matched well with the (001), (100), (101), (110), and (111) planes of Ni(OH) 2 (JCPDS 14-0117). 52 As for 8% Ni-ZIS and the other Ni-ZIS samples with different contents of Ni(OH) 2 (Fig.…”

Removal of Tetracycline Hydrochloride by Photocatalysis Using Electrospun PAN Nanofibrous Membranes Coated with g-C3N4/Ti3C2/Ag3PO4

“…To further clarify the process and mechanism of the photocatalytic reaction, the effect of free radical trapping agent on the catalytic activity of the nano-fiber photocatalytic film was studied, and the main active substances for the oxidative degradation of TC were determined. As shown in Figure 9 b , EDTA-2Na, IPA and BQ are the trapping agents of hole (h + ), hydroxyl radical (•OH) and superoxide radical (•O 2 − ) respectively [ 5 , 26 ], and their dosage is 1 mM·L −1 . After adding EDTA-2Na, IPA and BQ into the reaction system, the R% value of TC decreased from 82.8% to 59.3%, 62.2% and 14.6%, respectively within 120 min of light radiation time.…”

“…Photocatalytic technology has the advantages of strong oxidation capacity, simple reaction conditions, high efficiency, low cost and harmless final products, and is considered to be an effective technology for treating antibiotic wastewater and reducing its drug resistance [ 2 ]. At present, the photo-catalysts used mainly include TiO 2 [ 3 ], Ag 3 PO 4 [ 2 , 4 ] and ZnIn 2 S 4 [ 5 ]. Although these photo-catalysts have significant degradation effects on antibiotics, there are still many shortcomings [ 4 ]: Fast recombination rate of photo-generated carriers, low utilization rate of visible light, poor stability, poor recovery and reuse performance, etc.…”

Engineering of a Hybrid g-C3N4/ZnO-W/Cox Heterojunction Photocatalyst for the Removal of Methylene Blue Dye

“…Priorly, conventional remediation techniques such as activated carbon adsorption, filtration, extraction, oxidation, ultrafiltration, electrolysis, chemical oxidation and biological treatment were applied, and usually, the results of incomplete mineralization of pollutants were obtained. The present progressive research in the field of various advanced oxidation technologies has overcome the inadequacies of these conventional techniques [2]. A lot of researchers have made phenomenal exertions to explore more catalysts and innovative materials to degrade toxic organic pollutants of wastewater and have, providentially, found semiconductor photocatalysis technology as a significant treatment to partially solve energy shortages and water pollution problems [3,4].…”
