Still, they have not yet developed to a catalytic performance level that would enable widespread adoption.

Here, we discuss the sonication fabrication and extraordinary catalytic activity of MoS<sub>2</sub>/g-CN in alkaline media as an OER electrocatalyst. Various techniques like X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) and scanning electron microscopy (SEM) are employed to evaluate the structure, surface characteristics and morphology.

It showed increased OER activity by maintaining high stability for about 35 h. Our results suggest that graphitic carbon nitride can produce steady and sustainable energy and that transition metal chalcogenides with specific morphologies can improve electrocatalytic efficacy.

In this review, we show how sol-gel synthesis has played a central role in the development of ionogel materials. Ionogels are effectively ‘wet gels’. They are formulated to enable hydrolysis and condensation of alkoxysilane precursors but use an IL as the solvent phase. ILs, which are considered to be room temperature molten salts, have minimum vapor pressures and thus do not evaporate. At the nanoscale, the resulting ionogel possesses a nanofluidic state, but macroscopically it is solid. This unique microstructure enables the ionogel to exhibit the excellent electrochemical properties of the IL including high ionic conductivity, a wide electrochemical stability window along with good thermal and mechanical stability. The nanofluidic state ensures that there is excellent electrical contact between the solid electrode and the pseudo-solid electrolyte. This overcomes one of the problems associated with solid-state batteries, namely solid-solid interfaces. Ionogels have already been used in a number of electrochemical applications including lithium-ion and sodium-ion batteries as well as lithium metal and sodium metal batteries. The electrochemical properties of ionogels, their applications in battery systems and future opportunities in consumer electronics, transportation and the grid are highlighted.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":664,"journal":{"name":"Journal of Sol-Gel Science and Technology","volume":"113 1","pages":"70 - 85"},"PeriodicalIF":2.3,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142941116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
