As non-renewable resources continue to dwindle, the importance of green energy generation and storage is growing. In order to store energy effectively, especially for renewable sources, a reliable energy storage system needs to be developed. In this study, CoCr<sub>2</sub>O<sub>4</sub> (CCO) and N-rGO/CCO were fabricated employing a hydrothermal approach. The electrochemical performance of CCO and N-rGO/CCO was assessed by GCD at 1 A g<sup>-1</sup>, CCO and N-rGO/CCO nanohybrid displayed specific capacitances (C<sub>s</sub>) of 497.6 and 1062.25 F g<sup>-1</sup>, respectively. The structural defects and uniform anchoring of CCO nanoparticle on N-rGO nanosheets result in the improved electrochemical perfomance and C<sub>s</sub> of the N-rGO/CCO nanohybrid being consistently superior than CCO across all current densities. Furthermore, in two-electrode systems exhibit C<sub>s</sub> of 225.72 F g<sup>-1</sup> with P<sub>d</sub> (880 W kg<sup>-1</sup>), confirming the symmetric behaviour of N-rGO/CCO. In a 2-electrode setup, N-rGO/CCO demonstrate outstanding supercapacitive performance. This is due to the unique characteristics of N-rGO, which provide a flexible and scalable framework for the growth of CCO nanoparticles. Moreover, N-rGO/CCO nanohybrid has substantial potential to be used for supercapacitor electrode material, offering greater E<sub>d</sub> (6.06 Wh kg<sup>-1</sup>). Electrochemical investigations indicates that N-rGO improves CCO stability by enhancing C<sub>s</sub> through an extended discharge lifespan. N-rGO nanosheets within the nanohybrid enhance electron flow by acting as a conductive substrate. As a result, the N-rGO/CCO is an outstanding material for electrodes in supercapacitors and various energy storing devices.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1040 ","pages":"Article 123824"},"PeriodicalIF":2.1,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144886862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
