Partially unzipped carbon nanotube (PU-CNT) was prepared from carbon nanotube (CNT). Palladium (Pd) nanoparticles were deposited on PU-CNT by reduction method. Prepared Pd/PU-CNT was characterized by X-ray diffraction (XRD), transmission electron microscope (TEM) and scanning electron microscope (SEM). Electrochemical characterization was performed by Cyclic Voltammetry and Linear Sweep Voltammetry. Pd/PU-CNT exhibited higher oxygen reduction reaction (ORR) activity in presence of methanol than Pd/C and Pd/Graphene. [ABSTRACT FROM AUTHOR]
