[ 1 ] - The effect of time and temperature on the growth and morphology of cupper oxide nanostructures
Cupper Oxide structures with a variety of novel morphologies are synthesized using cupper foil as substrate via a solution route. The structure, morphology and phase of the as-synthesized nanostructures are analyzed by various techniques. SEM images show gradual development of hierarchical structures of copper oxide with different morphology. In order to study the effect of reaction time and te...
[ 2 ] - Photo-electrocatalytic activity of TiO2 nanotubes prepared with two-step anodization and treated under UV light irradiation
To improve the photo-catalytic degradation of salicylic acid, we reported the fabrication of ordered TiO2 nanotube arrays by a simple and effective two-step anodization method and then these TiO2 nanotubes treated in a methanol solution under UV light irradiation. The TiO2 nanotubes prepared in the two-step anodization process showed better photo-catalytic activity than TiO2 nanotubes prepared ...
[ 3 ] - تهیه و شناسایی الکتروشیمیایی فیلم پلی آنیلین حاوی نانوذرات گرافن کوانتوم دات به منظور الکترواکسیداسیون اسکوربیک اسید
فیلم کامپوزیت پلی آنیلین/گرافن کوانتوم دات/طلا (Au/PANI-GQD) از طریق فرآیند الکتروشیمیایی دو مرحله ای تهیه شد. در مرحله اول، مخلوط آنیلین و GQD حرارت داده، رفلاکس شده و بعد الکتروپلیمریزاسیون انجام شد. در مرحله دوم از طریق آبکاری الکتروشیمیایی، نانوذرات طلا بر روی سطح فیلم PANI-GQD ایجاد شد. ساختار الکترود PANI-GQD و Au/PANI-GQD توسط روبش میکروسکوپ الکترونی (SEM) و IR شناسایی شد. نتایج نشان داد...
[ 4 ] - Effect of composition electrolyte on the morphology and photocatalytic activity of anodized titanium nanoporous
The morphology of titanium dioxide and titanium dioxide-tungsten trioxide nanocomposite films fabricated by anodizing in a glycerol solution containing 0.13 M NH4F and different quantity of Na2WO4 was investigated as a function of sodium tungstate concentrations. The effects of sodium tungstate concentration on the surface morphology were observed by scanning electron microscopy (SEM). It was c...
