Nitrogen-doped TiO2 mesosponge layers formed by anodization of nitrogen-containing Ti alloys

An alloy containing 5 at.% of N was produced by arc melting of Ti and TiN powders. By anodization of the alloy in a 10 wt.% K 2 HPO 4 /glycerol electrolyte at 140 °C, oxide mesosponge layers can be formed with thickness as up to several micrometers. X-ray photoelectron spectroscopy confirms nitrogen...

Zusammenfassung:An alloy containing 5 at.% of N was produced by arc melting of Ti and TiN powders. By anodization of the alloy in a 10 wt.% K 2 HPO 4 /glycerol electrolyte at 140 °C, oxide mesosponge layers can be formed with thickness as up to several micrometers. X-ray photoelectron spectroscopy confirms nitrogen uptake in the oxide. Photoelectrochemical measurements show successful N-doping of these mesoporous anodic layers with a significant visible light photoresponse.
