Microstructure and photocatalytic performance of micro arc oxidation coatings after heat treatment
Source abstract
Abstract
Abstract A V-doped titania catalyst was synthesized on titanium substrate by micro-arc oxidation and then it was carried out by heat treatment in nitrogen atmosphere. The surface characteristics of the synthesized titania coatings were investigated by SEM, EDS, XPS and XRD. The synthesized TiO 2 coating doped with V (in form of V 2 O 3 and V 2 O 5 ) showed a large amount of “cellular” bulges with more microscopic defects. The anatase phase of the TiO 2 coatings after heat treatment tended to be transformed into rutile phase. As a result, the corrosion resistance and photocatalytic performance of TiO 2 coating doped with V after heat treatment had been enhanced.
