Here, we have demonstrated selective oxidation of primary sp3(C)-H bond in toluene to benzyl benzoate using biomass derived chemically activated carbon channels supported NiFe2O4 NPs as catalyst under visible LED light. [Display omitted] •Use of robust and inexpensive nano-NiFe2O4@CAGC as heterogeneous catalyst.•Very selective oxidation of toluene to benzyl benzotate.•Expensive Au/Pd-free protocol.•Reusable catalyst.•Bio-waste management. Here, we report an efficient and highly selective oxidation of primary carbon-hydrogen bond in toluene catalyzed by biomass, rice husk derived chemically activated graphitic carbon supported NiFe2O4 (nano-NiFe2O4@CAGC) nanomaterial under LED light. The hybrid nanocatalyst showed excellent activity and selectivity towards direct oxidation of toluene to benzyl benzoate. The nano-NiFe2O4@CAGC has also demonstrated superior catalytic activity compared to its individual components. The catalyst was very robust and stable under the reaction conditions, and was separated from the reaction mixture by an external magnet and reused for subsequent reactions.
