Herein, the phase and photocatalytic property of graphitic carbon nitride (g-C3N4) are modulated with the functionalization of ionic liquid (IL) by post-treatment of g-C(3)N(4 )with imidazolium sulfonic acid chloride. The structure, morphology and optoelectronic properties of synthesized catalyst were thoroughly investigated. The functionalization of Ionic liquid has induced polycrystallinity to the amorphous g-C3N4. The g-C3N4 -IL is highly efficient towards photocatalytic side-chain oxidation of toluene using H2O2 with toluene conversion of 58% with 97% benzaldehyde selectivity in acetonitrile and toluene conversion of 49% and 96% benzaldehyde selectivity in organic solvent-free conditions. The synergy between g-C3N4 and the IL elevates the visible light absorption and lower photoluminescence intensity. The g-C3N4-IL catalyst efficiently halts over-oxidation to get high selectivity for the desired product. In addition, graphene oxide and reduced graphene oxide were also functionalized with IL to examine their photocatalytic efficiency and considerable efficiencies were observed. The g-C3N4-IL is highly stable and recyclable.
