| 摘 要： | 200 ℃下四方结构的二氧化钛(TiO2)与氧化石墨烯(GO)复合纳米晶在一个装有适量钛酸四丁酯、无水乙醇、氧化石墨烯和蒸馏水的密闭的水热釜中加热12 h后被制备。X射线粉末衍射仪（XRD)、扫描电子显微镜（SEM）、透射电子显微镜（TEM）等一系列分析仪器被运用来揭示二氧化钛与氧化石墨烯复合纳米晶是由粒径大约160 nm的四方结构的二氧化钛纳米晶与氧化石墨烯复合而成,通过紫外吸收对其光学性能进行了必要的测试。

| Abstract: | TiO2/graphene oxide nanocrystals with tetragonal structure were synthesized at 200 ℃ in a closed vessel consisting of an appropriate amount of the mixture solution containing Ti(OC4H9)4 and absolute ethanol, graphene oxide and distilled water for 12 h. The results of X-ray powder diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) indicated that TiO2/graphene oxide nanocrystal was made up of tetragonal structure TiO2 with diameter less than 160 nm and graphene oxide. The UV measurement result indicated that the TiO2/graphene oxide composite nanocrystal had a potential photoelectrochemical conversion property. |
