Copper and zinc oxide reaction
WebThis study concerns the design of an ion-imprinted polymer (IIP) for the selective detection of mercury II ions. Compared to other electrochemical studies, the originality of this work lies to the fact that the IIP was electropolymerized on ZnO nanorods, which were themselves grown on gold/diazonium modified substrates. This strategy of diazonium salt and ZnO … WebCopper does not react with water, but it does slowly react with atmospheric oxygen to form a layer of brown-black copper oxide which, ...
