Crystallographic analysis using X-ray diffraction (XRD) and morphological characterization <em>via</em> high-resolution scanning electron microscopy (HRSEM) were conducted. The electrochemical evaluation demonstrated remarkable supercapacitor performance, with a specific capacitance of 306.7 F/g at 1 A/g, highlighting exceptional charge storage capacity. Even at a higher current density of 2 A/g, the composite maintained substantial reversible capacity (198.6 F/g), higher capacitance retention (95.7 %), and Coulombic efficiency (86.2 %) over 6000 cycles, showcasing its robust stability. At a challenging current density of 10 A/g, the specific capacitance remained high at 85.4 F/g.

Particularly noteworthy was the predominance of capacitive behavior, constituting 78.4 % at an accelerated scan rate of 100 mV/s.

The influence of contact time, adsorbent dose, adsorbate concentration and temperature on the adsorption are analyzed. The kinetics and equilibrium studies are also carried out.

The first involves recycling the spent lithium-ion batteries (LIBs) and the second involves the degradation of the antibiotics found in water. It has been possible to synthesize reduced graphene oxide (RGO) from used LIBs that have also been doped with boron (BRGO). A nanocomposite (BWO/BR) is formed when BRGO and a visible active Bi<sub>2</sub>WO<sub>6</sub> (BWO) are mixed together. The structural, morphological, and spectroscopic characterizations confirm the formation of BRGO, BWO, and BWO/BR nanocomposite. The antibiotics tetracycline hydrochloride (TCH) and ciprofloxacin (CIP) have been tested for photocatalytic degradation with all three of the newly made materials. It is found to decrease the bandgap of BWO (2.73 eV) to 2.22 eV upon combining with BRGO. Under visible light, BWO/BR exhibits elevated TCH degradation (93 %), which is found to increase in the presence of sunlight (95 %). In the presence of BWO/BR, the degradation of CIP was reported to be 72, 95, and 97.5 % in UV, visible, and sunlight, respectively. The effect of reaction conditions like pH, amount of catalyst and initial concentration were examined towards degradation of TCH and CIP in presence of BWO/BR. It has been discovered that pH 6 and 8 are ideal for TCH and CIP, respectively. Studies on TCH and CIP degradation in pharmaceutical effluent were also conducted; in the presence of BWO/BR and visible light, the degradation efficiencies were determined to be 69 and 72 %, respectively. All of the zone of inhibition of <em>E. Coli,</em> L. <em>monocytogenes, S. typhimurium,</em> and <em>S. aureus</em> were examined in presence of BWO/BR before and after exposure to visible light for 90 min, during which time a near-zero zone of inhibition was seen. There were investigations using liquid chromatography-mass spectrometry (LC-MS) to identify the intermediate products of TCH and CIP degradation.</p></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"19 ","pages":"Article 100569"},"PeriodicalIF":6.2,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666523923002039/pdfft?md5=b784935429f3fef511ace7d5323474cd&pid=1-s2.0-S2666523923002039-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139108932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
