CH3OH electrooxidation by nanosized Pd loaded on porous LaMnO3

Abstract Generating the multifunctional influence by adding a promoter or employing a support for electrocatalytic particles is a remarkable approach to advance the efficiency and stability of anode electrode in the non-reforming methanol fuel cell. So, the coprecipitation assisted with ultrasonic is selected to fabricate porous LaMnO3; and the nanosized Pd is loaded on LaMnO3 via wetness incorporation. The samples are characterized through scanning electron microscopy, Fourier-transform infrared spectroscopy (FT-IR), vibrating sample magnetometry, Energy-dispersive X-ray spectroscopy (EDX), Transmission electron microscopy (TEM), Brunauer-Emmett-Teller and X-ray diffraction analysis. The electrochemical studies are carried out to identify the behavior and efficiency of electrocatalysts toward CH3OH electrooxidation. Based on adsorption/desorption of hydrogen, the electrochemical surface area presented an ascending performance as nanosized Pd (76.63 m2 g−1)
