In order to enhance the photodegradation of methyl orange (MO) by ZnO under visible light irradiation, ZnO nanoparticles co-doped with Ag and N and supported on activated carbon (AC) with different properties were synthesized through the sol-gel method. The prepared photocatalysts were characterized in terms of the structure and properties through X-ray diffraction, N₂ adsorption-desorption, ul...

To enable the reuse of carbon dioxide (CO2), electrocatalytic reduction CO2 (CO2RR) into syngas with a controllable H2/CO ratio is considered cost-effective and intriguing approach. Here, number silver (Ag)-doped, zeolitic imidazole framework composites were prepared by facile method. The outcomes demonstrate that electroreduction on Ag-doped ZIF-8 catalysts produces just CO H2, without having ...

The photoinduced formation of silver (Ag) clusters and particles in poly(vinyl alcohol) poly(acrylic acid) blend films is described. The photoreduction of the Ag is achieved by subjecting the Ag doped films to 350 nm photons. The formation of Ag clusters and particles is monitored using UV-VIS spectroscopy. Films treated with H2O2 exhibit bleaching of the UV-VIS signals corresponding to Ag clus...

We report a simple approach for preparing undoped and Pt-doped Fe(2)O(3) thin films with excellent photoactivity via facile hydrothermal growth. The photocurrent densities of undoped and Pt-doped Fe(2)O(3) thin films were recorded up to 1.2 and 1.38 mA cm(-2) at 0.23 V Ag/AgCl under 1 sun illumination, respectively.

Doping with intentional impurities is an intriguing way to tune the properties of semiconductor nanocrystals. However, the synthesis of some specific doped semiconductor nanocrystals remains a challenge and the doping mechanism in this strongly confined system is still not clearly understood. In this work, we report, for the first time, the synthesis of stable and water-soluble Ag-doped CdTe se...

TiO2 nanoparticles are surface-modified via atom transfer radical polymerization (ATRP) with a hydrophilic poly(oxyethylene)methacrylate (POEM), which can coordinate to the Ag precursor, i.e. silver trifluoromethanesulfonate (AgCF3SO3). Following the reduction of Ag ions, a Nb2O5 doping process and calcination at 450 °C, bi-functional Nb-doped TiO2/Ag ternary nanostructures are generated. The r...

It is important to develop functional transmucosal implant surfaces that reduce the number of initially adhering bacteria and they need to be modified to improve the anti-bacterial performance. Commercially pure Ti sheets were anodized in an electrolyte containing ethylene glycol, distilled water and ammonium fluoride at room temperature to produce TiO2 nanotubes. These structures were then ann...

Advanced solar cell contacts feature local contacts to pand pSi. In this review existing models for contact formation to p and p The formation of the local Al BSF as applied in PERC like solar cell structures is inhibited by the formation of voids. It is shown that the formation of voids depends on process parameters and their influence on the contact formation is reviewed. Using an analytical ...
