Given the narrow band gap enabling excellent optical absorption, increased charge carrier density and accelerated surface oxidation reaction kinetics become the key points for improved photoelectrochemical performances for water splitting over hematite (α-Fe2O3) photoanodes. In this study, a facile and inexpensive method was demonstrated to develop core/shell structured α-Fe2O3 nanorod arrays. ...

Silver doped TiO2 nanoparticles have been prepared by liquid impregnation (LI) and photodeposition (PD) methods and characterized by surface analytical methods such as scanning electron micrographs (SEM) and X-ray diffraction (XRD). The photocatalytic activity of silver doped TiO2 was tested by photocatalytic degradation of C.I. Acid Red 88 (AR88) as a model compound from monoazo textile dyes. ...

In this study we demonstrate that self-doping and surface plasmon resonance could endow a wide-band-gap ternary semiconductor BiOCl with remarkable visible light driven photocatalytic activity on the degradation of organic pollutants and photocurrent generation properties. The self-doped BiOCl with plasmonic silver modification was synthesized by a facile one-pot nonaqueous approach and systema...

In the present study, silver-doped TiO2 (Ag/TiO2) nanoparticles were prepared by various Ag doping (wt%) and a combination of sol-gel and ultrasound irradiation. Ag/TiO2 nanoparticles were characterized by energy-dispersive X-ray analysis (EDX), scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. Based on the Taguchi method, photocatalytic...

In-vitro performance under clinically relevant environmental conditions aging enables clinical use. Functionalized fillers are proposed as reinforcing particles in light-cured for applications. Silica-silver-graphene (SiO 2 -Ag-Gr), silver-doped (HA-Ag), silver doped (HA-...

Under 4.507 eV excitation, the SrS : Cu,Ag thin "lms exhibited a saturated blue emission at 2.876 eV at room temperature and two additional emission bands at 3.443 and 2.398 eV were also observed at 10 K. By comparing with singly doped SrS : Cu and SrS : Ag, the two bands at 3.443 and 2.876 eV were assigned to the Ag emission bands and the 2.398 eV band to Cu emission. The enhancement of the 2....

Hammada scoparia (Pomel) is a powerful plant with important biological properties. In this study, we report on the green synthesis of silver-doped nickel and copper nanoparticles (NPs) in presence H. leaf extract using self-propagating sol–gel autocombustion process. The synthesized NiO, CuO, Ag-NiO, Ag-CuO NPs were characterized Fourier transform infrared spectroscopy (FTIR) X-ray diffraction ...

The aim of this work was to study the physical and antibacterial properties of a flowable resin composite incorporating a sol-gel derived silver doped bioactive glass (Ag-BGCOMP). The depth of the cure was calculated by measuring the surface micro-hardness for the top and bottom surfaces. The volumetric polymerization shrinkage was measured by recording the linear shrinkage as change in length,...

A simple, inexpensive and one-step synthesis route of Ag-TiO2 nanoparticles by arc discharge method isreported. The resulting nanoparticles were characterized using X-ray diffraction and scanning electronmicroscopy. X-ray diffraction patterns demonstrate dominance of rutile to anatase phase in TiO2 andformation of silver metal on TiO2 after arc discharge process. Scanning electron microscopy im...

This study examined the theoretical impact and modelling of photocatalyst, WO3, on organic pollutant wastewater treatment. The electronic band structures, total density state, all optical properties, photocatalytic activities under UV or visible light were investigated by using first principle method for WO3 Ag doped 3% 6%. In order to calculate gap, generalized gradient approximation (GGA) bas...
