论文摘要
已经提出了一种新颖的设计，用于在干燥的惰性大气下在金属氧化物颗粒（石墨烯/tiox@Tio2）上轻松且快速地积累高度可量身定制的纳米结构的多壳，以最大程度地提高可见光光催化性能。我们还彻底，系统地研究了制备准备的纳米结构颗粒表面以及Tiox@Tiox@Tio2纳米颗粒上非凡的原位石墨烯生长的机制，在金属氧化物（TIO2）/聚合物（聚合物甲基甲基甲基甲酯）界面中的快速共符号反应中获得了快速共符号反应。还发现，与传统的合成途径相比，与Heter-hetero-junction对TiO2的同性污染物降解相比，还发现具有更好的光催化活性，可以进行更好的光催化活性。
A novel design has been proposed for a facile and rapid build-up of highly tailorable nanostructured multishells on metal oxide particles (graphene/TiOx@TiO2) under a dry inert atmosphere to maximize the visible-light photocatalytic performance. We also thoroughly and systematically investigated the as-prepared nanostructured particle surface and the mechanisms of the extraordinary in-situ graphene growth on the TiOx@TiO2 nanoparticles achieved by a rapid-concomitant reaction in the metal oxide (TiO2)/polymer (polymethyl methacrylate) interface under microwave irradiation. The as-prepared composite materials are also found to perform a better photocatalytic activity in comparison to the traditional synthesis pathway for degradation of organic pollutants under visible light, associated with the synergetic effects of homo-/hetero-junction on TiO2.
