Nevertheless, the choice of electrolyte remains challenging due to the inability to initiate the electron-hole combination, resulting in intercalation without further fragmentation, depriving the material of the non-fluorescent nature in aqueous and non-aqueous electrolytes. Therefore, an ionic liquid (IL), namely 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF4), is used to overcome this issue due to longer cationic interaction of the butyl group, which facilitates the intercalation with subsequent fragmentation. Moreover, unique properties like negligible vapor pressure, high thermal stability, wide electrochemical potential window, low viscosity, good ionic conductivity, and recyclability make IL a green alternative to conventional solvents. The high dielectric constant and these properties make IL a suitable electrolyte for the exfoliation of melamine by electrochemical methods to synthesise g-C3N4 QDs. IL can also enable more favourable configuration of the transition states, especially when we look at the mechanistic details of kinetically sluggish reactions like ORR while using electrocatalysts. In this regard, various steps involved in the ORR in an aqueous electrolyte are as follows :
