In this study, abundant and cheap graphite support (G) was modified with chitosan (Chit) and amine groups to obtain N-Chit-G and subsequently decorated with copper nanoparticles (CuNPs). The nanocomposites thus obtained were characterized at different stages of the synthesis using various techniques such as transmission electron microscopy, X-ray photoelectron spectroscopy, Brunauer-Emmett-Teller, carbon-hydrogen nitrogen sulfur analyzer, cyclic voltammetry, and electrochemical impedance spectroscopy. Results showed that CuNPs had been uniformly and finely decorated on the N-Chit-G support, in which copper was in the predominant form of Cu(I). The Randles-Sevcik equation revealed the high active surface area of Cu N-Chit-G compared to the remaining composites obtained. Oxygen reduction reaction (ORR) at Cu@N-Chit-G was evaluated by linear sweep voltammetry using a rotating disk electrode in a KOH solution (0.1 mol L-1) saturated with O-2 and O-2 plus MeOH (1.0 mol L-1) to find the good electrocatalytic capability of Cu@N-Chit-G for ORR with a small onset potential of 0.74 V (vs. RHE). A KOH solution, saturated with MeOH (1.0 mol L-1), revealed good 10000 s durability of Cu@N-Chit-G electrocatalyst with a slow drop in the current (91%). Finally, ORR kinetic investigations were conducted using the Koutecky-Levich (K-L) plot to find the ORR progress through a 4e(-) pathway. (C) 2019 Hydrogen Energy Publications LLC.
