The film had a spongelike porous configuration with a uniform hole size of approximately 20 nm (see picture). The formation mechanism has not yet been clarified, but carbonaceous matter produced by the anodic reaction of oxalate ions likely contributes to the growth of numerous nanopores on the gold anode.
