Monitoring the formation of PtNi nanoalloys supported on hollow graphitic spheres using in situ pair distribution function analysis.
This article aims to address the formation and the structural disordering/ordering phenomena of PtNi nanoalloys supported on hollow graphitic spheres (HGSs) using pair distribution function (PDF) analysis under ex situ/in situ data collection conditions. Starting from small nanoparticles (10-15 Å in diameter) embedded in HGSs, structural changes were monitored during stepwise heating and coolin...
متن کاملInstantaneous Green Synthesis of Zerovalent Iron Nanoparticles by Thuja orientalis Extract and Investigation of Their Antibacterial Properties
The applications of zerovalent iron nanoparticles in environmental remediation have led to the development of green methods in their synthesis. This study for the first time reports on the green synthesis of zerovalent iron nanoparticles using Thuja orientalis extract as the reducing and capping agent at room temperature. The synthesized nanoparticles were characterized with different tec...
متن کاملSynthesis of Silver Nanoparticles from Spent X-Ray Photographic Solution via Chemical Rreduction
Silver metal was recovered primarily from spent X-ray photographic solution using a horizontal tube furnace. The X-Ray Diffraction (XRD) spectroscopy analysis approved almost 95 percent purity of the recovered silver metal. In the next step, the synthesis of silver nanoparticles from the recovered silver metal proceeded by using chemical reduction method. The proposed method uses e...
متن کاملSynthesis of Nickel/ Molybdenum Oxide Bimetallic Nanoparticles via Microwave Irradiation Technique
Nickel-molybdenum oxidebimetallic nanoparticles were synthesized in ethylene glycol using the microwave irradiation technique. According to the results, successive reduction of nickel and molybdenum ions, followed by thermal treatment of obtained nanoparticles led to formation of core-shell structured nickel-molybdenum oxide nanoparticles. According to the results, the thickness of the s...
متن کاملExperimental Investigation on the Synthesis and Size Control of Copper Nanoparticle via Chemical Reduction Method
In this study, synthesis of copper nanoparticles and effect of the reaction conditions on the particle size were investigated. The copper nanoparticles were synthesized and stabilized in a narrow temperature range in the presence of polyvinylpyrrolidone under nitrogen atmosphere. Reaction temperature and concentration ratio of the reducing agent to the precursor (R/P) as two main conditions i...
