The main motivation of incorporating MAA in symbiotically configured nanocomposites is with regard to MAA green, nontoxic nature, UV absorption and photostability. Our facile one-pot solvothermal method is to facilitate the amalgamation of MAA and molybdenum disulfide-graphene (MG) composite at the molecular/nanoscale level to endow better photocatalytic functionality. It is observed that the rate of photocatalytic dye degradation of Rhodamine 6G (R6G) becomes consistently enhanced with an incremental increase in the concentration of MAA in MG. The combination of MG-MAA leads up to 81.2% quenching of the PL emission, as compared with MG. Noticeable decrease in PL lifetime from 280 ps (MG) to 77 ps (MG-MAA) explicitly implies fast charge extraction and transport of the charge carriers.
