Morphology alteration of nickel microstructures for glycerol electrooxidation

Shape-controlled microstructures (triangles and urchin-like) of Ni were synthesized using polyol synthesis in the presence/absence of capping agent (polyvinilpyrrolidone, PVP). Direct visualization of crystal structure and morphology before/after electrochemical tests in KOH were characterized using electron microscopy techniques. Electrochemical characterizations illustrated that urchin-Ni-PVP has highest catalytic activity among all …
