在本論文中，主要是探討HCl濃度、合成溫度、H2O2濃度等參數，探討對TiO2漿料的性質變化，並以分解一定量之1mg/L甲基橙染料來量測其光觸媒效率。隨著HCl的濃度增加，TiO2的結晶相會從銳鈦礦相，逐漸的長出金紅石相，因而擁有混晶相的性質，且光觸媒效率也隨之增加。本實驗HCl濃度之最佳值為1.2M做。在60℃合成溫度時，其形態為棒狀與球狀混合，並為纖維狀的Rutile相與顆粒形態的Anatase相的混合晶相，其擁有相對於純纖維狀與純顆粒形態較為快速的光觸媒效率，所得粉末可在約50分鐘內便能將1mg/L的甲基橙分解完全，本實驗的最佳合成溫度為60℃。添加H2O2可使1mg/L甲基澄的分解時間縮短至4~5分鐘。本實驗的H2O2理想濃度約在10mM至1M之間，另外添加H2O2溶液也可使TiO2漿料在可見光下也能有光觸媒反應，約2小時便能將1mg/L的甲基橙分解完畢。

The effect of the HCl concentration and the reaction temperature on the formation of TiO2 powder was investigated. The H2O2 addition to improve the photo catalysis properties (which was measured by the decomposition of methyl orange dye) of TiO2 slurry was also discussed in this article. The rutile phase in the formation powder was increased to formed the mixing phase TiO2 by increasing the HCl concentration. The mixing phase powder leads to improve the photocatalytic efficiency of TiO2 powder. According to the experimental results, the best HCl concentration is about 1.2M HCl. The product shows the rod-like with spherical powder mixture as the formation temperature at 60℃. The rod-like particles are rutile phase TiO2 and the spherical particles are anatase TiO2. The photocatalyst efficiency of this mixture is better than that of pure rutile or pure anatase powder. The 1mg/L methyl orange can be decomposed completely after exposing in UV light for 50 min. The best formation temperature is at 60℃. In addition, the photocatalysis can be improved by adding H2O2 to TiO2 slurry. The better concentration of H2O2 is in the range 10mM ~ 1M. The 1mg/L methyl organic was completely decomposed during 4~5 min by using TiO2 with H2O2. Adding H2O2 can also enhance photocatalysis property of TiO2 slurry in the visible light. The 1mg/L methyl organ could be completely decomposed during 2hr as exposing in visible light.
