Since hydrogen represents an alternative energy source to carbon-based fuel, there is a need to be able to split water using water oxidation catalysts (WOC) preferably by renewable energy sources such as sunlight. In this HOT article, the Spiccia group present a facile preparation of NiOx films for use as WOC. These WOC films, deposited from macrocyclic Ni complexes in alkaline solution, were significantly more catalytically active at higher pH (12.9), therefore widening the range of conditions over which they can be deposited. Enhanced catalytic activity was also observed in visible light, indicating the films are electrochromic.
