copper nanoparticles were fabricated by electro-reduction of cuso4solution in the presence of cetyltrimethylammonium bromide (ctab) cationic surfactant as an additive through potentiostatic method. the prepared copper nanoparticles were characterized by scanning electron microscopy (sem) and electrochemical methods. the sem images reveal that the nanoparticles with diameters at about 70 n...

A rational design for oxygen evolution reaction (OER) catalysts is pivotal to the overall efficiency of water electrolysis. Much work has been devoted understanding cation leaching and surface reconstruction very active electrocatalysts, but little on intentionally promoting in a controlled fashion. We now report controllable anodic Cr CoCr2O4 by activating pristine material at high potential, ...
