ABSTRACT=<p>Electrocatalytic active species like transition metal oxides have been widely combined with carbon-based nanomaterials for enhanced Oxygen Reduction Reaction (ORR) studies because of the synergistic effect arising between different components. The aim of the present study is to synthesize CeO<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub> system and compare the ORR activity with bare CeO<sub>2</sub>. Ceria (CeO<sub>2</sub>) embedded on g-C<sub>3</sub>N<sub>4</sub> nanocomposite was synthesized by a single-step microwave-mediated solvothermal method. This cerium oxide-based nanocomposite displays enhanced ORR activity and electrochemical stability as compared to bare ceria.</p>
