Highly ordered, and conductive inverse
opal arrays were made with silica and subsequently coated with tin-doped
indium oxide (ITO) via atomic layer deposition (ALD). We demonstrate
the utility of the resulting mesostructured electrodes by further
coating them with nickel oxide via ALD. The NiO-coated arrays are
capable of efficiently electrochemically evolving oxygen from water.
These modular, crack-free, transparent, high surface area, and conducting
structures show promise for many applications including electrocatalysis,
photocatalysis, and dye-sensitized solar cells.
