Surface modification with a nanomaterial has been confirmed to be an effective strategy enhance the visible-light photodegradation efficiency of titanium dioxide nanoparticles (TiO2-NPs). In this regard, we used silver as additive into TiO2-NPs improve their activity under visible light irradiation. Here, novel and eco-friendly process was developed prepare Ag-doped TiO2 nanohybrid named photon...

In this study adsorption of arsenic (As) onto TiO2 nanoparticles and the facilitated transport of As into carp (Cyprinus carpio) by TiO2 nanoparticles was examined. Adsorption kinetics and adsorption isotherm were conducted by adding As(V) to TiO2 suspensions. Facilitated transport of As by TiO2 nanoparticles was assessed by accumulation tests exposing carp to As(V) contaminated water in the pr...

Hybrid multi-functional nanomaterials comprising two or more disparate materials have become a powerful approach to obtain advanced materials for environmental remediation applications. In this work, an Ag-Ag2O/TiO2@polypyrrole (Ag/TiO2@PPy) heterojunction has been synthesized by assembling a self-stabilized Ag-Ag2O (p type) semiconductor (denoted as Ag) and polypyrrole (π-conjugated polymer) o...

Recently, there has been increased interest in electrospun-titanium dioxide nanofibers (TiO2 NFs) as antibacterial agents owing to their advantages, such as simple and cost-effective fabrication processes, and high surface areas. However, the photocatalytic effects of TiO2 NFs are relatively low because of their low-ordered crystalline structure, and the antibacterial effect is only effective u...

The growing challenges of environmental purification by solar photocatalysis, precious metal free catalysis and photocurrent generation in photovoltaic cells are receiving the utmost global attention. Here we demonstrate the one-pot green chemical synthesis of a new stable heterostructured, eco-friendly, multifunctional micro-composite consisting of α-Bi2O3 micro-needles intercalated with ancho...

Water borne pathogens present a threat to human health and their disinfection from water poses a challenge, prompting search for newer methods and newer materials. Disinfection of Gram-negative bacterium Escherichia coli and Gram-positive coccal bacterium Staphylococcus aureus in aqueous matrix was achieved within 60 and 90 minutes respectively at 350C using solarphotocatalysis mediated by sono...

Due to the release of active pharmaceutical compounds in wastewater and their persistence environment, dangerous consequences can develop aquatic terrestrial organisms. Chitosan/Ag/TiO2 3D printed scaffolds, at different Ag nanoparticle concentrations (10, 100, 1000 ppm) are investigated here as promising materials for photocatalytic degradation under UV–Vis irradiation wastewater. As target dr...

Bamboo-type TiO2 nanotube arrays prepared via anodic oxidation are modified with Ag nanoparticles by pulsed electrochemical deposition, for improved lithium-ion intercalation property as the anode material in lithium-ion batteries. Heat treatment converts as-formed nanotubes into anatase for Ag deposition. Bare and Ag-modified nanotubes are cycled at a current density of 800 μAcm between 1.0 an...
