NANOCRYSTALLINE AND COARSE GRAINED POLYCRYSTALLINE NICKEL CATALYSTS FOR THE HYDROGEN EVOLUTION REACTION
The objective of this work was to study electrocatalytic properties of the coarse grained polycrystalline nickel cathodes: bulk Ni, foam Ni, and electrodeposited Ni in comparison with those of nanocrystalline nickel catalyst for the hydrogen evolution reaction (HER) in 1.0 M NaOH solution. According to voltammetry and electrochemical impedance spectroscopy results, the intrinsic reactivity of polycrystalline Ni-cathodes, investigated for the HER, increases as follows: electrodeposited < foam < bulk Ni. The highest catalytic reactivity of nanocrystalline Ni cathode results from its favourable microstructural properties. The intercrystalline volume fraction contributes to the overall rate of the HER using spillover effect. It was found that spillover effect plays a major role in determining the overall catalytic activity of nanocrystalline catalyst.
