Moreover, the FeMoO<sub>4</sub>/r-GO composite has Tafel of 47 mV dec<sup>−1</sup> compared to FeMoO<sub>4</sub> (61.7 mV dec<sup>−1</sup>). EIS confirmed the low impedance values of FeMoO<sub>4</sub>/r-GO composite and good ECSA value which definitely confirmed the high catalytic properties of the generated composite. Thus, all these results confirmed that this generated hybrid is optimal preliminary strategy for producing exceptional catalysts for water splitting, and further, it can be used in energy storage devices in the form of supercapacitors and batteries, which make use of the high capacity and permeability of FeMoO<sub>4</sub>-based composites, such as rGO.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"155 ","pages":"Article 112322"},"PeriodicalIF":4.3,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143833706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
