Abstract

The interactions of organic molecules such as acetonitrile, propylene carbonate, and sulfolane on the electrogenerated nickel fluoride films were investigated using cyclic voltammetry and scanning electron microscopy. The effect of water, alkali metal fluorides, fluoride content, and acidity are also reported. Based on these studies, the potential effect of these factors on electrochemical perfluorination processes are projected. Water and alkali metal fluorides would enhance the dissolution of nickel fluoride film. Organic molecules like acetonitrile dissolve nickel fluoride film, while propylene carbonate forms thick polymeric layers on nickel surface. Higher acidity and fluoride ion content enhance the stability of a thin, catalytically active nickel fluoride film. Organic reactants like sulfolane form a composite film with nickel fluoride and, thus, enhance the long-term stability and electrocatalytic activity.
