本文采用简便的溶剂热法制备了在次氯酸钠预活化的碳纤维(CF)表面生长的六方Zn2GeO4纳米棒。通过理论计算和在石墨烯二维平面上生长 Zn2GeO4 的模拟实验,研究了可能的生长机制。附着在CFs表面的Zn2GeO4纳米棒的(113)晶面是最稳定的结构。由于Zn2GeO4的光催化活性和CFs优异的吸附能力之间的协同作用,所得的Zn2GeO4/CFs复合材料对对甲苯胺的氧化表现出优异的光催化活性。
In this paper, hexagonal Zn2GeO4 nanorods grown on the surface of carbon fibers (CFs) that were pre-activated by sodium hypochlorite were prepared by a facile solvothermal method. The possible growth mechanism has been investigated by theoretical calculations and a simulation experiment by growth of Zn2GeO4 on a 2D flat surface of graphene. The (113) crystal facet of Zn2GeO4 nanorods attached to the CFs surface was the most stable structure. Due to the synergistic effect between the photocatalytic activity of Zn2GeO4 and excellent adsorption capacity of CFs, the resultant Zn2GeO4/CFs composites exhibited excellent photocatalytic activity for oxidation of p-toluidine.
