Since metal nanoparticles have a high surface-to-volume ratio and very active surface atoms, they are very attractive catalysts for a wide variety of organic and inorganic reactions, compared to bulk catalysts. Metal nanoparticles suspended in colloidal solutions and those adsorbed onto bulk supports have been used as catalysts for a wide variety of carbon-carbon bond formation reactions such a...

In this report, we propose and demonstrate the fabrication of a highly-specific SERS substrate, which was achieved by the co-precipitation of functional materials, such as nanosorbents and nanocatalysts, into Ag nanoporous films. Based on the nanostructures developed, we performed the ultrasensitive detection of arsenic ions by SERS and monitored the catalyzed reactions using real-time SERS.

The manufacturing, application, and design of chemical processes products that minimize or remove waste the use dangerous toxic reagents are referred to as green chemistry. Green chemistry is made up twelve principles, one which catalysis. role catalysis accelerate reaction by introducing a substance called catalyst. Because their high efficiency, productivity, activity, selectivity, nanocataly...

In spite of the numerous advances in development H2 and O2 evolutions upon water splitting, separation from still remains a severe challenge. Herein, novel dual-functional nanocatalysts Pd/carbon nanosphere (CNS), obtained via immobilization ultrafine Pd nanoparticles onto CNS, are developed employed for both selective generation HCOOH dehydrogenation evolution H2O2 decomposition. these reactio...

in the present study, ptruce/mwnts nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (mor). to characterize the nanocatalysts, tem, xrd, eds and xps are investigated. cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activity and stability of the catalysts in methanol electro-oxi...

Size-controlled Pt nanocatalysts embedded in TiO(2) were successfully synthesized by simultaneous dual-gun sputtering and were found to exhibit unique electronic properties depending on their size, which affected the potential of zero total charge, CO-bulk oxidation, and methanol oxidation reaction.
