Synthesis and Characterization of Strontium and Potassium Titanates Nanotubes Nanorods and their Applications

Abstract

The excessive use of organic dyes are widely used in fabric, paper, leather, newlinepharmaceuticals, cosmetics and food industrial purposes can cause adverse effects on human newlinebeings and animals. Generally, adsorption, filtration, electrochemical, and advanced oxygen newlineprocess (AOP) techniques etc., are employed for the waste water treatment which have their own newlinelimitations. Therefore, this necessitates the development of a highly sensitive, simple, advanced, newlineeffective strategy for the degradation of organic dyes using modified metal-metal oxide nanotubes newlineand nanorods. Methylene Blue (MB), Rhodamine B (Rh B), Methyl Orange (MO) and Tartrazine newline(TZ) dyes were used as the organic pollutant to mimic the waste water treatment. newlineThe anatase Titanium dioxide nanoparticles (TiO2 NPs) were synthesized by using green newlineroute method with the help of Azhardichta indica leaf extract and Strontium Nitrate as precusor newlinesynthesized the cubic, perovskite Strontium Titanate Nanotubes (SrTiO3 NTs) by hydrothermal newlinemethod. By using Sol-gel method Strontium Titanate Nanorods (SrTiO3 NRs) and Strontium newlineTitanate Nanoparticles (SrTiO3 NPs) were synthesized. newlinePotassium Titanate (K2Ti6O13) Nanotubes (KTNTs) and Potassium Titanate (K2Ti6O13) newlineNanoparticles (KTNPs) were synthesized by the simple, effective hydrothermal method all other newlinecondtions were same except with different reaction time period. Potassium Ttanate Nanorods newline(KTNRs) were synthesized by the traditional Molten Salt Solution (MSS) method. The as newlinesynthesized different morphologies of the effective metal-metal oxide semiconductors were newlinecharacterized by X-ray diffraction (XRD), UV-Visible Spectroscopy, Forier Transform Infra Red newlineSpectroscopy (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray newlineSpectroscopy (EDX), Brunauer-Emmett-Teller (BET) Surface area analysis and Transmission newlineElectron Microscopy (TEM) which were confirmed the morphologies of the nanosized Strontium newlineTitanate and Potassium Titanates. newlineThe effect of pH, initial concentaration of the dyes, effect o
