چکیده
Trong nghiên cứu này, hạt xúc tác nano hợp kim platinum-ruthenium-cobalt (PtRuCo) trên chất nền hỗn carbon Vulcan XC-72 với ống đa thành (C-MWCNTs) được tổng bằng phương pháp đồng khử. Hạt PtRuCo từ các tiền H2PtCl6, RuCl3, CoCl2, và khử là NaBH4 kết ethylene glycol (EG). Các mẫu sau khi chế tạo đánh giá bởi đo phổ tán xạ năng lượng tia X (EDX), nhiễu (XRD), kính hiển vi điện tử truyền qua (TEM), quét thế vòng tuần hoàn (CV). quả đạc phân tích cho thấy, ba phần khả oxy hóa methanol cao hơn 10% chống ngộ độc CO gấp đôi so hai PtRu. Hơn nữa, C-MWCNTs hoạt tính 5% kháng 83% carbon.

Automatic Searching for English-Vietnamese Documents on the Internet
Bilingual corpora together with machine learning technology can be used to solve problems in natural language processing. In addition, bilingual corpora are useful for mapping linguistic tags of less popular languages, such as Vietnamese, and for studying comparative linguistics. However, Vietnamese corpora still have some shortcomings, especially English–Vietnamese bilingual corpora. This pape...
متن کاملFabrication and Optimization of ChE/ChO/HRP-AuNPs/c-MWCNTs Based Silver Electrode for Determining Total Cholesterol in Serum
The developed method used three enzymes comprised of cholesterol esterase, cholesterol oxidase, and peroxidase for fabrication of amperometric biosensor in order to determine total cholesterol in serum samples. Gold nanoparticles (AuNPs) and carboxylated multiwall carbon nanotubes (cMWCNTs) were used to design core of working electrode, having covalently immobilized ChO, ChE, and HRP. Polyacryl...
متن کاملFacile Synthesis of Core/Shell-like NiCo2O4-Decorated MWCNTs and its Excellent Electrocatalytic Activity for Methanol Oxidation
The design and development of an economic and highly active non-precious electrocatalyst for methanol electrooxidation is challenging due to expensiveness of the precursors as well as processes and non-ecofriendliness. In this study, a facile preparation of core-shell-like NiCo2O4 decorated MWCNTs based on a dry synthesis technique was proposed. The synthesized NiCo2O4/MWCNTs were characterized...
متن کاملNano-kinetics of probe-particles in solution visualized by a pin-fiber video scope.
The nano-kinetics of colloidal particles and living cells with the colloidal particles were visualized by a newly developed video scope. The system of the new video scope has a feature of fine controlling the illumination conditions by using a single optical fiber. This characteristic enables one to obtain clear images of living cells and the motions of colloidal particles by light-scattering e...
متن کاملElectro-Catalytic Activities of Binary Nano-Composites of Pt and Nano- Carbon/Multiwall Carbon Nanotube for Methanol Electro-Oxidation
Binary nano-composites of Pt and nano-carbon (NC) and Pt and multiwalled carbon nanotube (MWCNT) have been prepared with varied compositions ranging between 20 and 80wt% Pt and investigated them as electrocatalysts for methanol oxidation. The study shows that with the increase in wt% of NC, the apparent electro-catalytic activity of the composite catalyst increases initially, reaches maximum at...
