pd nanoparticles immobilized on hybrid composite of g-c3n4-rgo as efficient catalyst for ethyl benzene oxidation to acetophenone

In this study, the hybrid composite of graphitic carbon nitride (g-c3n4) and reduced graphene oxide (rgo) was synthesized by a simple wet impregnation method and was used as support for palladium nanoparticles. the catalytic performance of ternary composite pd/g-c3n4-rgo was investigated through the oxidation reaction of ethylbenzene in the presence of tbhp as oxidant reagent and the result showed 67% conversion and 97% selectivity toward acetophenone under optimized conditions. in addition, the proposed catalyst also retained its activity and selectivity for acetophenone after 5 runs.
