Titanium dioxide is a promising photocatalyst for water splitting, but it suffers from low visible light activity due to its wide band gap. Doping can narrow the gap of titanium dioxide; however, new charge-carrier recombination centres may be introduced. Here we report design sub-10 nm rutile nanoparticles, with an increased amount surface/sub-surface defects overcome negative effects bulk defects. Abundant not only shift top valence upwards band-gap narrowing also promote separation. The...
