[ 1 ] - Enhanced Electrocatalytic Activity of Pt-M (M= Co, Fe) Chitosan Supported Catalysts for Ethanol Electrooxidation in Fuel Cells
Here, metal nanoparticles were synthesized by chemical reduction of the corresponding metal salts in the presence of chitosan polymer. Binary and ternary metallic-chitosan Pt-Fe-CH, Pt-Co-CH and Pt-Fe-Co-CH nanocomposites were prepared. Transmission electron microscopy images and UV–Vis spectra of the nanocomposites confirmed the presence of the metal nanoparticles. The electrocatalytic activit...
[ 2 ] - Microwave-Assisted Chemical Preparation of ZnO Nanoparticles and Its Application on the Improving Grain Yield, Quantity and Quality of Safflower (Carthamus Tinctorius L.)
ZnO nanoparticles were synthesized by a microwave-assisted chemical method. ZnO nanostructures were synthesized via a fast reaction between zinc acetate and ammonia at presence citric acid and other effective agents in chemical procedure. Nanostructures were characterized by X-ray diffraction , scanning electron microscopy. Seed yield and seed quality of safflower grown under drought stress. Th...
[ 3 ] - سنتز و مطالعه فعالیت کاتالیزوری بسیار موثر نانوذرات پلاتین- اورتوفریت لانتانیم قرار گرفته در بستر پلی آنیلین-کیتوسان برای الکترواکسیداسیون متانول
در این پژوهش، پلی آنیلین (PA) همراه با کیتوسان (CH) به عنوان بستری موثر و مناسب برای نانوذرات استفاده گردید. نانوذرات اورتوفریت لانتانیم (LFO) با روش سل-ژل سنتز و با تکنیک های پراش پرتو ایکس (XRD) و طیف سنجی پراکندگی انرژی پرتوی ایکس (EDS) شناسایی گردید. نانوکاتالیست Pt-LFO/PA-CH با کاهش شیمیایی هگزاکلروپلاتینیک اسید به وسیله سدیم تتراهیدروبورات در حضور نانوذرات LFO در بستر PA-CH تهیه شد. شکل ظ...
[ 4 ] - Enhanced Catalytic Activity of Pt-NdFeO3 Nanoparticles Supported on Polyaniline-Chitosan Composite Towards Methanol Electro-Oxidation Reaction
In this work, NdFeO3 nanoparticles were synthesized through a simple co-precipitation method. The formation of NdFeO3 particles was verified by X-ray powder diffraction, infrared spectroscopy, vibrating sample magnetometer, and transmission electron microscopy analysis. Polyaniline and chitosan were employed as proper support for production of metal nanoparticles. Novel Pt...
