Abstract

The formation mechanism of zinc oxide (ZnO) hollow hexagonal nanotowers (h-HNTs) synthesized using a simple hydrothermal method was studied. Crystal growth and dissolution mechanism were correlated to the formation of voids and grain boundaries in the nanotowers and are supported by imaging evidence for the first time. Elevated reaction temperature, various ions present in the reaction medium and these voids are responsible for the adsorption-dissolution process and formation of ZnO h-HNTs.

摘要

研究了采用简单水热法合成的氧化锌（ZnO）空心六角纳米塔（h-HNTs）的形成机理。晶体生长和溶解机制与纳米塔中孔隙和晶界的形成相关，并且首次得到了成像证据的支持。升高的反应温度、反应介质中存在的各种离子以及这些孔隙导致了吸附-溶解过程和ZnO h-HNTs的形成。
