Synthesis of Bimetallic Platinum Nanoparticles for Biosensors
The use of magnetic nanomaterials in biosensing applications is growing as a consequence of their remarkable properties; but controlling the composition and shape of metallic nanoalloys is problematic when more than one precursor is required for wet chemistry synthesis. We have developed a successful simultaneous reduction method for preparation of near-spherical platinum-based nanoalloys conta...
متن کاملInstability of Supported Platinum Nanoparticles in Low-Temperature Fuel Cells
This paper discusses the mechanisms of surface area loss of supported platinum (Pt) electrocatalysts in lowtemperature fuel cells. It is argued that submonolayer dissolution of Pt nanoparticles governs the surface area loss at high voltages by increasing the loss of Pt from carbon and coarsening of Pt nanoparticles on carbon.
متن کاملCell-targeted platinum nanoparticles and nanoparticle clusters.
Herein, we report the facile preparation of cell-targeted platinum nanoparticles (PtNPs), through the design of peptides that, as a single molecule added in small concentration during the synthesis, control the size of PtNP clusters during their growth, stabilise the PtNPs in aqueous suspension and enable the functionalisation of the PtNPs with a versatile range of cell-targeting ligands. Water...
متن کامل“Cubic” Colloidal Platinum Nanoparticles
Transition metals have long been used as catalysts in the form of dispersions stabilized on inorganic substrates such as silica gel, alumina, and activated charcoal.1 More recently, colloidal platinum nanoparticles have been used as catalysts and photocatalysts in solutions.2 Aqueous colloidal platinum particles are mostly prepared by the reduction of a platinum salt by hydrogen, photochemical,...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
