It is shown that growing zirconium hydroxide particles have an hierarchical structure with a constant ratio of the average particle sizes between two consecutive levels of the hierarchy. This feature is common to titanium and zirconium hydroxide nanoparticles, which, however, differ in reactivity Полный текст |
