Extensive studies on the electrochemical, photocatalytic and antimicrobial applications of bio assisted nano titania

Abstract

AbstractIn recent days synthesis and structuring of intelligent nano materials investigated and reported has developed critical scientific ideas to deal with different industrial, social and environmental issues. The excellent thermal, optical and electrical properties along with its resistant to corrosion, wear, oxidation and erosion enabled them unique for sustainable environmental applications. In this view nano structured Titanium di oxide particles synthesized from its precursor via template assisted sol–gel technique have been verified as corrosion inhibitor of brass alloy in acid medium along with its photo catalytic and anti-microbial applications. The physico-chemical parameters of the synthesized nano materials were studied using XRD, FT-IR, UV-DRS, SEM, TEM and BET analytical techniques and revealed the impact of tea leaf extract as a template in producing a nano catalyst NTG about 14 nm in size with tailored structural, optical and morphological characteristics. The rate of corrosion of a specimen in acid medium is verified by weight loss method and the inhibitor efficiency increased with the increase in concentration of the nano catalyst. The catalytic activity is proved against the photo degradation of a toxic melamine, a trimer of cyanamide. The synthesized nano catalyst showed excellent antimicrobial properties proven against the growth of K. pneumonia and H. influenza.
