在本研究中，透過微波水熱法成功合成Bi2WO6/BiOCl異質結構複合材料光觸媒。並以XRD、FE-SEM、光催化降解實驗、UV/VIS-DRS、PL以及BET分析材料的組成成分、表面形貌、在模擬日光下對CIP的降解效率、對可見光的吸收能力、電荷載子生命週期以及比表面積大小，再由這些結果推測Bi2WO6/BiOCl此材料的光催化反應機制。
從研究實驗結果可看出，在形成Bi2WO6/BiOCl異質結構後可以使能隙下降、提高電荷載子的生命週期以及增加光觸媒粉末之比表面積，有效提升對CIP的降解效果。且在降解溶於去離子水中的10 ppm CIP溶液時，在以氙燈照射120分鐘後，能夠將CIP降解為初始濃度的96.5%，並且在後續的五次循環降解實驗中，降解率皆維持在93%以上，證明了此材料在光降解反應中具有一定的穩定性。
在確定Bi2WO6/BiOCl能有效降解溶於去離子水中之CIP後，在本研究中也將CIP溶於自來水、溪水、海水中，再以Bi2WO6/BiOCl降解這些溶於這些水中的CIP，模擬Bi2WO6/BiOCl在自然情況下將CIP的降解情形。而從實驗結果中可看出，Bi2WO6/BiOCl對於溶於自來水及溪水中的CIP有一定的降解效果，但在降解溶於海水中之CIP時，會受海水中氯離子的影響，使降解率大幅下降。

In this study, Bi2WO6/BiOCl heterostructure composite photocatalysts were successfully synthesized using the microwave hydrothermal method. The composition, surface morphology, degradation efficiency of CIP under simulated sunlight, visible light absorption capacity, charge carrier lifetime, and specific surface area of the materials were analyzed using XRD, FE-SEM, photocatalytic degradation experiments, UV/VIS-DRS, PL, and BET. Based on these results, the photocatalytic reaction mechanism of the Bi2WO6/BiOCl material was inferred.
The experimental results revealed that the formation of the Bi2WO6/BiOCl heterostructure resulted in a decreased band gap, enhanced charge carrier lifetime, and increased specific surface area of the photocatalytic powder, leading to an improved degradation efficiency for CIP. When degrading a 10 ppm CIP solution in deionized water under xenon lamp irradiation for 120 minutes, the CIP concentration was reduced to 96.5% of the initial concentration. Furthermore, in subsequent five-cycle degradation experiments, the degradation rate remained above 93%, indicating a certain level of stability of this material in photocatalytic degradation reactions.
After confirming the effective degradation of CIP in deionized water by Bi2WO6/BiOCl, the study also investigated the degradation of CIP dissolved in tap water, river water, and seawater using Bi2WO6/BiOCl, aiming to simulate the degradation of CIP by Bi2WO6/BiOCl under natural conditions. The experimental results showed that Bi2WO6/BiOCl had a certain degradation effect on CIP dissolved in tap water and river water. However, when degrading CIP dissolved in seawater, the degradation rate was significantly reduced due to the presence of chloride ions in seawater.
