(1) the substitution of larger ce 4+ (0.097 nm) by smaller cu 2+ (0.072 nm). First, the oxidized surface of the cu foam was dissolved by h + to release cu + followed by complexation of the cu + with h + and cl − to form h x cucl 1+x.
This phenomenon can be attributed to the coexistence of two opposite effects (fu et al. Since no cu 2 o peaks were observed during the reduction process, the cuo is thought to have been reduced directly to cu without passing through the intermediate cu 2 o.
