本研究使用鐵和還原石墨烯對二氧化鈦進行改性，以提高光催化劑在可見光下的氧化效率。通過活性實驗確定最佳金屬摻雜比例以獲得最大的污染物降解效率，並了解改性光催化劑在不同環境（如溫度、相對濕度、進流濃度、停留時間）下的降解性能。為了研究金屬鐵、還原石墨烯和二氧化鈦在降解過程中的協同效應，輔以TGA、FTIR、XRD、XPS、TEM、SEM和EPR等特性分析，對活性結果進行分析驗證實驗。在 XRD 圖中，銳鈦礦與板鈦礦的重量百分比約為 7:3。此外，XRD結果中光催化劑的d-間距與TEM得到的結果相似。XPS分析結果表明TiO2和0.1wt%rGO/FeX/TiO2光催化劑中的鈦金屬以Ti4+的形式存在。此外，XPS 分析的官能基團與 FTIR 分析得到的相似。EPR 分析結果表明，0.1wt%rGO/Fe0.5%TiO2 樣品的 OH 自由基數量最多，這表明 0.1wt%rGO/Fe0.5%TiO2 可以產生最多的OH自由基去除苯乙烯，此結果也與活性實驗一致。在動力學研究中，模型 4 最適合本研究的反應動力學。 0.1rGO/Fe0.5%TiO2光催化降解苯乙烯的Arrhenius方程得到的活化能為123.6 kJ/mol。

This experiment will use iron and reduced graphene to modify titanium dioxide improving the oxidation efficiency of the photocatalyst under visible light. In this study, the activity experiment was used to decide the best metal doping ratios to obtain the most pollutant degradation efficiency, and to understand the degradation performance of the modified photocatalyst under different environments (such as temperature, relative humidity). In order to research the synergistic effect of metallic iron, reduced graphene and titanium dioxide during degradation, supplemented by characteristic analysis such as TGA, FTIR, XRD, XPS, TEM ,SEM and EPR were carried out to analyze and prove the results of the activity experiment. In the XRD pattern, the weight percentage of anatase to brookite was about 7:3. Furthermore, the d-spacing of photocatalysts from the results of XRD were similar to the results obtained by TEM. The XPS analysis results showed that the titanium metal in TiO2 and 0.1wt%rGO/FeX/TiO2 photocatalysts was in the form of Ti4+. In addition, the function groups analyzed by XPS were similar to that obtained by FTIR analysis. The EPR analysis results indicated that the 0.1wt%rGO/Fe0.5%TiO2 sample had the greatest number of OH radicals, which showed that 0.1wt%rGO/Fe0.5%TiO2 could generate the greatest number of hydroxyl radicals for the removal of the styrene, this result was also consistent with the activity experiment. In kinetic study, model 4 was best fitted to the reaction kinetics of this study. The activation energy obtained by the Arrhenius equation in the photocatalytic degradation of styrene by 0.1rGO/Fe0.5%TiO2 was 123.6 kJ/mol.
