Abstract

---

Nano structured titania composites have been expansively studied under heterogeneous photo catalysis, self cleaning, antimicrobial and antitumor applications. In this work a series of titania-Chitosan nano composites were prepared by in-situ sol-gel technique and widely characterized using conventional techniques. Chitosan used was derived from mushroom, fungi to manipulate the resultant nano materials to mixed anatase-rutile phased with irregular morphology and particle size ranging from 10-11 nm. The visible light bioactive nano catalysts with unique bathrochromic shift (421 nm) and low band gap energy (2.64 eV) comprehensively enabled photo degradation of Congo red, a model pollutant to show 100 % discoloration and 82 % demineralization. The catalysts were subjected to further investigations for in-vitro anti bacterial, anti fungal and cyto toxicity against human pathogens. The results has shown that synthetic method has no influence on the physico-chemical characteristics as well as applications of nano materials produced and Chitosan as an efficient biotemplate in enhanced biocompatibility. Thus visible active TiO2-chitosan composites produced by sol-gel technique can act as best sustainable green catalyst and recommended further in bio-medical and tissue engineering. Keywords:- Mesoporous, nanomaterials, anti-microbial, absorption edge, contaminant, red shift.
