Sintered Mo_xS_y (CO)_n and Mo_x (CO)_n: application in oxygen reduction reaction, hydrogen evolution and supercapacitors

摘要

Mo_x(CO)_n and Mo_xS_y(CO)_n ectrocatalysts were synthesized following a sintering process in air at 150℃. The catalysts were characterized using techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and cyclic as well as linear voltametry measurements. The results indicated that sintered Mo_x (CO)_n possesses catalytic activity for oxygen reduction reaction. Incorporation of sulfur to the carbonyl compound seems To nullify the catalytic activity of the material. These materials are porous in nature and formed in amorphous form or With poor crystallinity. The voltammograms indicated its possible application in supercapacitor electrodes and for hydrogen Evolution reaction.
