Radiation-induced reduction of mixed silver and rhodium ionic aqueous solution

Abstract

Silver and rhodium metal nanoparticles were synthesized by electron beam and g-radiolysis of mixed solutions containing (Rh II acetate) dimer and Ag + sulfate in variable proportions. From the observation of the optical absorption spectra, transmission electron microscopic images and local X-ray analysis at increasing doses, it is concluded that the metals are segregated into two populations, which are randomly distributed according to the mixture content, one of 1.5-2 nm pure rhodium clusters, and the other of 15-20 nm pure silver clusters. At complete reduction of both metals, the Ag nanoparticles are systematically surrounded by the small rhodium clusters. r

A review on radiation-induced nucleation and growth of colloidal metallic nanoparticles

“…There are several reports about using poly(vinyl alcohol) (PVA) as a colloidal stabilizer for the synthesis of metallic nanoparticles by ionizing radiation [ 38 - 40 ]. The PVA chain plays a significant role in avoiding the formation of metal hydroxide clusters by hydrolysis of metal ions, thus preventing them from aggregation.…”

Synthesis and use of bimetals and bimetal oxides in contaminants removal from water: a review

“…Radiolysis is an efficient method to synthesize bimetals. 58 By this method, aqueous solution with metal precursors and stabilizer ligand is irradiated by g-rays to generate solvated electrons. Metal ions can accept electrons to form metal atoms.…”

Radiation-Induced Formation of Chromium Oxide Nanoparticles: Role of Radical Scavengers on the Redox Kinetics and Particle Size

“…This principle has been applied in making noble metal nanoparticles (of silver and gold) from dissolved metal ions, taking advantage of the strong reducing power of •e aq -produced by radiolysis . [19][20][21][22][23][24][25][26][27][28] More recently we have applied this process to making transition metal oxide nanoparticles from dissolved metal ions, taking advantage of either the strong reducing power of •e aq -or the strong oxidizing power of •OH, depending on the redox potential of the initially dissolved metal species. We have fabricated γ-FeOOH from Fe 2+ , 29 .…”
