A metal oxide nanocomposite including metal oxide nanoparticles distributed over a carboxymethylcellulose (CMC) shell. The metal oxide nanoparticles include at least one metal oxide nanoparticle selected from nickel oxide nanoparticles and cobalt oxide nanoparticles. A working electrode can be modified with the metal oxide nanocomposite to provide a nanohybrid electrode. The nanohybrid electrode can be effectively used in urea fuel cells (UFCs) to achieve electrochemical oxidation of urea.
