An N-doped TiO2 layer with enhanced hardness and photocatalytic performance was fabricated on a titanium (Ti) substrate through anodization in a non-aqueous electrolyte comprising nitrate and glycerol, followed by heating at 723 K in air. Glycerol as an electrolyte solvent formed a homogeneous and d...
