Abstract
The Nd-TiO2 micro-arc oxidation (MAO) coatings were formed in phosphate-based electrolyte with the addition of Nd2O3 using suitable voltage and frequency. SEM results revealed that the coatings were varied with different voltage and frequency. And composition analysis showed the Nd-TiO2 coatings are mainly composed of anatase and rutile phase. Meanwhile, the anatase content increased and then decreased. In addition, XPS results indicated that the Ti2p spin-orbit components of Nd-TiO2 coatings are shifted towards higher binding energy, suggesting that some of the Nd3+ ions are combined with TiO2 lattice and led dislocation. Furthermore, the photocatalytic experiment results showed that the photocatalytic activity of Nd-TiO2 coatings can be greatly enhanced with moderate amount of Nd3+. However, excessive amount of Nd3+ is not of an effective impact on the improvement of photocatalytic activity.
期刊介绍：
Materials Research is constantly evolving and correlations between process, structure, properties and performance which are application specific require expert understanding at the macro-, micro- and nano-scale. The ability to intelligently manipulate material properties and tailor them for desired applications is of constant interest and challenge within universities, national labs and industry.
