                 摘要:以葡萄糖为碳源、NH 4 Cl 为发泡剂、纳米金属 Fe 为促进葡萄糖石墨化的催化剂,制备了 Fe@GE 复合材
                 料,通过 UV-vis、Raman 分析表明,复合材料 Fe@GE 石墨化程度高,石墨烯膜缺陷少;再以 Fe@GE 作为基
                 质材料,采用低温水热法成功将其与纳米 Cu 进行复合,制备了三维 Fe@GE-Cu 复合材料。通过 TEM 和 FESEM
                 分析证明,Fe@GE 与纳米 Cu 成功复合;通过 XRD、FTIR 和 ICP 测试表明,复合材料 Fe@GE-Cu 在常态下较
                 为稳定。以 49 mL  (200 mg/L)重铬酸钾溶液为例,进行催化还原性能测试,加入 1 mL 质量分数为 88%的甲
                 酸水溶液后,再加入 10 mg  催化剂 Fe@GE-Cu 0.65 ,在 9 min 时,Cr(Ⅵ)已被全部还原,表明该复合材料具有高
                 效催化还原 Cr(Ⅵ)的性能,能有效解决重金属污染问题。

                 Abstract: A Fe@GE composite was synthesized by using glucose as carbon source, NH 4Cl as foaming
                 agent, iron nanoparticles as catalyst  to promote  the graphitization  of glucose.  The resulting Fe@GE
                 composite exhibited high degree of graphitization with less defects, which was confirmed by UV-vis and
                 Raman spectroscopy. Subsequently, Fe@GE composite combined with nano-Cu through low-temperature
                 hydrothermal method to  produce a three-dimensional  (3D) Fe@GE-Cu composite.  The  3D Fe@GE-Cu
                 composite was testified  by TEM and FESEM. In addition, the  Fe@GE-Cu composite was stable under
                 ambient state according to the analysis results of XRD, FTIR and ICP. The catalytic reduction activity of the
                 prepared composite was tested by the reaction of 49 mL K 2Cr 2O 7 solution (200 mg/L). After adding 1 mL
                 (mass fraction 88%) HCOOH and 10 mg Fe@GE-Cu 0.65 catalyst, Cr(Ⅵ) was completely reduced within 9
                 minutes, indicating that the composite Fe@GE-Cu 0.65 had high catalytic activity in the reduction of Cr(Ⅵ)
                 and could effectively solve the problem of heavy metal pollution.
