实验以钛酸四丁酯,盐酸,硫酸等试剂为原料,通过水热法在不同酸性和温度条件下分别制备了anatase和rutile不同比例混合的TiO2纳米粉体以及单纯的anatase相和rutile相.对不同条件制备的纳米粉体通过X射线粉末衍射(XRD),拉曼光谱(Raman),比表面积(BET),光致发光光谱(PL),高分辨透射电子显微镜(TEM)等进行了表征,研究在不同比例晶相混合下的光催化制氢的性能,探索最
ZnO作为一种直接带隙的宽禁带半导体,因其优异的光电特性及丰富的纳米结构特征在紫外激光、光致发光、场致发射、传感器、太阳能电池等领域都有广泛的应用.基于ZnO纳米材料的研究无论是理论上还是实际应用上都具有十分重要的意义.目前,常用的ZnO纳米线的制备方法众多,且可以生长出准一维的纳米线阵列,但是很难实现纳米线密度及单根纳米线直径与位置的调控.为了提高ZnO纳米线阵列的有序性以及位置的可控性,本论文
