Abstract

The synthesis and structure of intelligent nanomaterials have been studied and documented in recent times, leading to the increasing development of important scientific concepts. It was specially designed for sustainable environmental applications because to its exceptional thermal, optical, and electrical qualities as well as its resistance to wear, oxidation, corrosion, and erosion. Here, the corrosion inhibitory effects of nanostructured Titanium dioxide catalyst (NTG) on brass alloy in acidic media, as well as its photocatalytic and antimicrobial applications, have been confirmed. NTG was synthesized from its precursor using a template (green tea extract) aided sol-gel process. XRD, FT-IR, UV-DRS, SEM, TEM, and BET analytical techniques were used to study the physico-chemical parameters of the synthesized nanomaterials. The results showed the impact of a template like GTE in tailoring a nano catalyst NTG with a size of about 14 nm and customized structural, optical, and morphological properties. The weight loss technique is used to verify the corrosion rate of a specimen like brass strips under acidic conditions (1M HCl), and the inhibitory efficiency increases as the concentration of the nano catalyst increases. The photodegradation of a trimer of cyanamide, a hazardous compound, is used to demonstrate the catalytic activity. By using the disc diffusion method, it was confirmed that the synthesized nano catalyst exhibited outstanding antibacterial characteristics against the development of Haemophilus influenza (H. influenza, H.) and Klebsiella pneumonia (K. pneumonia, K.p.).
