ABSTRACT
Abstract Black precipitates were successfully obtained by radiolytic reduction of ammonium uranyl tricarbonate in the aqueous solution of HCOONH 4 by one step. TEM, SAED, EDS, and XRD analysis indicated that the precipitates consist of hollow UO 2 nanospheres ( ϕ : 30–50 nm, wall thickness: 8–15 nm, and cavity diameter: 10–20 nm). The effect of HCOONH 4 concentration, irradiation time and dose rate on the morphology, and size of nanospheres was investigated. Then, a gas-bubble template mechanism was proposed.
