S. Kapoor et al., PULSE AND GAMMA-RADIOLYTIC STUDIES ON THE FORMATION OF CD, PD AND CU CLUSTERS IN AQUEOUS-SOLUTIONS, Radiation physics and chemistry, 50(5), 1997, pp. 465-469
Investigations on the formation of Cd, Pd and Cu sols using radiolytic
techniques have been carried out. The reducing properties of the Cd p
articles were confirmed by dissolving MV2+, N2O and O-2. BY Using high
intensity electron pulses we observed the formation of the highly sta
ble (approx. 8 days) Cd particles that showed absorption at both 270 a
nd 450 nm. In the case of Cu, the stability of the sol depends on the
type of reducing radical used, such as formate and isopropanol. It has
been shown for Pd and Cd sols that the presence of both the stabilize
r and agglomerated particles play an important role in stabilizing the
small clusters. (C) 1997 Elsevier Science Ltd. All rights reserved.
