Journal of Electrochemistry

Nanocrystalline nickel exhibits electrocatalytic activity for methanol. In this work, nanocrystalline nickel coating has been obtained by using the double pulse method on glassy carbon materials surface. The influence of pulse conditions on the grain size of nanocrystalline nicke was studied. The concentrations and compositions of the plating bath were 300 g·L^-1 NiSO₄·6H₂O，45 g·L^-1 NiCl₂·6H₂O，40 g·L^-1 H₃BO₃，5 g·L^-1 C₇H₅NO₃S，and 0.05 g·L^-1 C₁₂H₂₅NaO₄S. The optimal pulse process parameters including the average pulse …
