Study on the Photocatalytic and Antibacterial Properties of TiO2 Nanoparticles-Coated Cotton Fabrics

Abstract

Herein, the amino-capped TiO2 nanoparticles were synthesized using tetrabutyl titanate and amino polymers by a two-step sol-gel and hydrothermal method technique for the fabrication of functional cotton fabric. The prepared TiO2 nanoparticles and the treated cotton fabric were characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), field emission scanning electron microcopy (FE-SEM) photocatalytic and antibacterial measurement. The results indicate the typical characteristic anatase form of the amino-capped TiO2 NPs with an average crystallite size of 14.9 nm. The treated cotton fabrics exhibit excellent antibacterial property and good photocatalytic degradation of methylene blue.

Merits of photocatalytic and antimicrobial applications of gamma-irradiated CoxNi1−xFe2O4/SiO2/TiO2;x= 0.9 nanocomposite for pyridine removal and pathogenic bacteria/fungi disinfection: implication for wastewater treatment

“…The OH radicals can destroy bacterial cells causing a reduction in cell coenzyme content. 65 In addition, it has been reported that metal oxides (MO) display a positive charge in slightly acidic medium, while microbes possess a negative charge. This creates an electromagnetic affinity between microbes and the MO, leading to oxidization of microbial cells and their subsequent destruction.…”

“…OH radicals can be also produced by irradiating the nanocomposite with UV. Due to the electron shift within the microbial cells and the nanocomposite, OH radicals can damage bacterial cells by reducing co-enzyme contents 99 .…”

“…x /GO through the introduction of 3, 4-dihydroxy phenyl acetic acid, which could bind with cotton fabric (Qi et al 2019). Zhang et al synthesized amino-capped TiO 2 using tetrabutyl titanate and amino polymers via two-step sol-gel, and further prepared the functional cotton fabric through hydrothermal method (Zhang et al 2019).…”
