In this study, spinel pure copper cobaltite CuCo<sub>2</sub>O<sub>4</sub> (CC0) and Fe doped CuCo<sub>2</sub>O<sub>4</sub> electrodes at different mole concentrations (FCC1–0.05 M, FCC2–0.1 M, FCC3–0.15 M, and FCC4–0.2 M) of metal mole complexes are made utilizing the sol-gel procedure using solvents such as citric acid and water. Using Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), Scanning Electron Microscope (SEM), HRTEM, and XPS, the resulting sample is systematically examined to analyze its functional group, crystallite size, shape, and chemical composition. All electrodes are Electric Double Layer Capacitors (EDLCs), according to the Cyclic Voltammetry (CV) test. The Galvanostatic Charge – Discharge (GCD) analysis confirmed that the pure CuCo<sub>2</sub>O<sub>4</sub> (CC0) electrode has a specific capacitance of 80.61F/g at the same current density, while the Fe doped 0.2 M CuCo<sub>2</sub>O<sub>4</sub> (FCC4) electrode has the highest specific capacitance, reaching 163.20F/g at a current density of 1 A/g. Following that, a two-electrode configuration is constructed, such as a Fe doped 0.2 M CuCo<sub>2</sub>O<sub>4</sub> (FCC4) electrode and an activated carbon (AC) electrode. With a specific capacity of 11.62 F/g at a current density of 1 A/g, an energy density of 2.32 Whkg<sup>-1</sup>, and an impressive power density of 149.99 Wkg<sup>-1</sup>, the ASC device exhibits outstanding characteristics. The device has a high total capacitive retention value of 99.84 % after 2000 cycles, and supercapacitor devices in particular show remarkable cycle stability.

The active species involved in degradation process were systematically investigated and a photo-catalytic mechanism was proposed. In addition, NiO NPs showed good recyclability and reusability of resistance to photo-corrosion even after 120 min of consecutive photo-catalytic activity. Overall, the green synthesized NiO NPs exhibited considerable potential for fast and eco-friendly removal of harmful organic dyes.</div></div>","PeriodicalId":9758,"journal":{"name":"Chemical Physics Impact","volume":"11 ","pages":"Article 100906"},"PeriodicalIF":3.8,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
