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...
متن کاملSynthesis of Pt nanopetals on highly ordered silicon nanocones for enhanced methanol electrooxidation activity.
Platinum (Pt) nanopetals were electrodeposited on highly ordered silicon nanocones (SiNCs) and explored as the electrocatalyst for methanol oxidation reaction (MOR) for direct methanol fuel cells applications. Highly ordered SiNCs array fabricated using the porous anodic aluminum oxide as the template had a high surface area. Well-dispersed Pt nanopetals possessing high electrocatalytic surface...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
