Elaboration and characterizations of platinum nanoparticles supported on cellulose - based carbon aerogel
Abstract. This work investigates the deposition of Pt nanoparticles onto carbon aerogels (CA), derived from microcrystalline cellulose. Nanoparticles are synthesised via impregnating the CA with H2PtCl6 followed by reduction either under H2 at 300 C or in a basic NaBH4 solution. H2 reduction yields uniform Pt nanoparticles (average diameter < 2nm) dispersed over the CA surface as revealed by Tr...
متن کاملTopochemical synthesis and catalysis of metal nanoparticles exposed on crystalline cellulose nanofibers.
Topochemical synthesis of gold nanoparticles (AuNPs) was achieved on crystalline cellulose single nanofibers (CSNFs), which were tailored from native cellulose. Exposed AuNPs@CSNFs composite exhibited an excellent catalytic efficiency: the turnover frequency of the AuNPs@CSNFs was up to 840 times that of conventional polymer-supported AuNPs, for a model aqueous reduction reaction. Our novel str...
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...
A rapid microwave route for the synthesis of ZnS nanoparticles
ZnS nanoparticles were synthesized via a simple surfactant free microwave route. In this synthesis, thioacetamide was used as sulfur source. The effects of different parameters such as type of zinc precursor, time and power of irradiation on the morphology and particle size of the products have been investigated. The nanostructures were characterized by ...
متن کاملSynthesis and Catalytic Features of Hybrid Metal Nanoparticles Supported on Cellulose Nanofibers
The structural and functional design of metal nanoparticles has recently allowed remarkable progress in the development of high-performance catalysts. Gold nanoparticles (AuNPs) are among the most innovative catalysts, despite bulk Au metal being regarded as stable and inactive. The hybridization of metal NPs has attracted major interest in the field of advanced nanocatalysts, due to electro-me...
