本研究利用固相燒結法製備InTaO4可見光觸媒粉末，實驗中以不同燒結溫度、不同核殼結構與不同反應物濃度比例，此三個參數製備光觸媒，並探討其對光觸媒效果之影響。實驗結果以X-ray繞射儀判別材料的結晶相，以掃描式&穿透式電子顯微鏡（SEM&TEM）鑑別粉體之表面形貌、成分分析及核殼結構，以UV-vis.分光光譜儀檢測光觸媒之光吸收波長範圍，並利用亞甲基藍溶液進行降解脫色實驗，以探討InTaO4在可見光照射下之催化能力。
結果顯示當燒結溫度高於850℃時InTaO4開始生成，並在1000℃時反應完全無殘留反應物。當Ta2O5:In2O3 =1:1之InTaO4產物其光觸媒效果隨InTaO4含量的提升而增強；而在Ta2O5:In2O3 =1.5:1與Ta2O5:In2O3 =1:1.5之核殼結構部分，結果顯示以Ta2O5為核之InTaO4光觸媒活性較佳。本實驗針對改變Ta2O5與In2O3之比例合成不同核殼厚度之光觸媒材料，隨著Ta2O5比例提升則核殼厚度隨之下降，因此導致電子電洞對再結合時間縮短使得光觸媒效果下降，本研究得出之最佳光催化能力反應參數為濃度比例Ta2O5:In2O3 =1.5:1且添加PVA時，燒結溫度在1100℃所反應之InTaO4光觸媒材料，具有最佳光催化能力，可在可見光照射六小時內，使得亞甲基藍濃度降解至0.13%。

In this research, InTaO4 were synthesized by solid-state reaction, using different synthesize temperature, different ratio of reactor and different core-shell structure as parameter. Then characterized the experiment result by X-ray diffraction (XRD) to determine structure, Scanning electron microscope (SEM) for Surface topography, Transmission electron microscope (TEM) for core-shell structure, and UV-visible spectrometer. The photocatalytic activity was evaluated by the photodegradation of methylene blue under visible light irradiation.
The result of experiment shows that when synthesize temperature is over 850℃, InTaO4 start to appear and the reaction complete at 1000℃, which means no reactor remain. When synthesize ratio is Ta2O5:In2O3 =1:1, photocatalytic will raise with the InTaO4. In the ratio of Ta2O5:In2O3 =1.5:1 and Ta2O5:In2O3 =1:1.5 are different core-shell structure, compare to the photocatalytic activity Ta2O5:In2O3 =1.5:1 is better . In the last experiment are changing the ratio of Ta2O5 and let InTaO4 have different length of shell, the length will decrease with Ta2O5 ratio raise, which lead to short the recombination time of the electron and electron hole and the decrease of photocatalytic properties. The result of the best parameter is Ta2O5:In2O3 =1.5:1 with PVA and under 1100℃ and it’s able to degradation MB concentration to 0.13% in 6 hour.
