Abstract

In this research, the radiation-heterogeneous processes of water decomposition on the surface of zirconium dioxide nanoparticles (n-ZrO2) were studied. The kinetics of buildup of molecular hydrogen during the radiolytic processes of water decomposition was also examined. The production of H2 and H2O2 through water radiolysis was investigated to develop a computational model and disclose the kinetic behavior of water radiolysis. The enthalpy of ZrO2 nanoparticles was studied at the temperature range T=1200-2900 K, in which ZrO2 nanoparticles has a two-phase transition. Some of the electrons were transported to the surface of the nanoparticles during the physical and physicochemical stages of the process and emitted into the water. At the same time, the migration of energy carriers in radioactively active oxide compounds changed at different intervals depending on the composition, structural stability, and electro-physical properties of the oxides.
伽玛射线作用下纳米zro2表面水的辐射解氢研究
研究了氧化锆纳米颗粒(n-ZrO2)表面水的辐射非均相分解过程。研究了水分解过程中氢分子积累的动力学过程。研究了水辐射解生成H2和H2O2的过程,建立了计算模型,揭示了水辐射解的动力学行为。研究了ZrO2纳米粒子在温度范围T=1200 ~ 2900 K时的焓值,在此温度范围内ZrO2纳米粒子发生了两相转变。在过程的物理和物理化学阶段,一些电子被传输到纳米粒子的表面,并排放到水中。同时,放射性活性氧化物中载流子的迁移随氧化物的组成、结构稳定性和电物理性质的不同而发生不同的时间间隔变化。
