Investigation of photocatalytic performance of titania based hybrid nanocomposite structure for dilapidation of organic contaminants

Abstract

This research paper attempt to provide the photocatalytic performance of nitrogen ion (N+) entrenched anodized Ti with hydroxyapatite hybrid nano-sctructure meant for dilapidation of organic contaminant from the environment. The N+ was entrenched at 70 keV with varying doses (1 × 1016, 5 × 1016, 1 × 1017 and 2.5 × 1017 N+/cm2) into anodized Ti surface. Functional groups, phase structure, topographic and morphologic characterizations of the synthesized hybrid nano-sctructure were analyzed using Infra Red Spectroscopy, X-ray diffraction and Microscopic techniques, respectively. Wettability of the specimens was found out using contact angle measurements. The anodized Ti specimens without N+ have exhibited less surface energy than the specimens with N+. Porous shell gets smoothened after the entrenchment of N+. Compared to all the doses of nitrogen implantation, better performance was observed for 5 × 1016 N+/cm2 dose. Moreover, the samples with N+ showed better charge transfer resistance indicating enhanced photocatalytic performance of N+ entrenched titania than other samples.
