Electronic properties of composite Fe and activated carbon (AC) were determined by using X‐ray photoelectron (XPS) and reflection electron energy loss (REELS), structural properties by X‐ray diffraction (XRD), and photo‐catalytic performance by ultra violet visible (UV‐Vis) spectroscopy. The intensity of low loss spectrum shows surface state at 5.42 eV is decreased with increasing the amount of AC indicated the Fe successfully oxidizes to form iron oxide. The bandgap was increased from 2.2 eV for 10% AC to 4.3 eV for 25% AC indicated the absorption wavelength shifted from the visible region to ultra‐violet region. The magnetic properties and porosity were increased with increasing the amount of AC in composites and show successfully used, as a magnetic trap of the charge (electron and hole) for producing radical atoms. The magnetic pore transformed from the disordered to ordered nature in the periodic structure was used to accelerate the degradation from 70.15% for 10% AC to 80% for 25% AC for 60 min. This study shows magnetic trap of composite Fe‐AC materials useful for enhanced photocatalytic performance.

减少铁碳（Fe-AC）复合材料的磁陷阱引起的电荷复合，从而增强光催化性能

通过使用X射线光电子（XPS）和反射电子能量损失（REELS）来确定复合铁和活性炭（AC）的电子性能，通过X射线衍射（XRD）来确定结构性能以及通过紫外光来确定光催化性能可见（UV-Vis）光谱 低损耗光谱的强度表明，5.42 eV处的表面态随着AC量的增加而降低，表明Fe成功地氧化形成氧化铁。带隙从10％AC时的2.2 eV增加到25％AC时的4.3 eV，表明吸收波长从可见光区移至紫外线区。磁性和孔隙率随复合物中AC含量的增加而增加，并已成功地用作电荷（电子和空穴）的磁性陷阱以产生自由基原子。在周期性结构中，从无序转变为有序性质的磁孔用于将降解从10％AC的70.15％加速到25％AC的80％的降解60分钟。这项研究表明复合Fe‐AC材料的磁阱可用于增强光催化性能。
