中文摘要:
      以葡萄糖为碳源,NH4Cl为发泡剂,纳米金属Co为促进葡萄糖石墨化的催化剂,通过一步法制备了Co-石墨烯复合材料,实现了石墨烯的形成和Co纳米粒子原位生长的同步进行。通过XRD、FTIR、XPS、Raman、UV-Vis和TEM对该复合材料的结构与形貌进行了表征。将Co-石墨烯复合材料运用于催化还原对硝基苯酚(4-NP)。在室温条件下,使用4 mg的催化剂可于8 min内将4-NP全部还原。复合材料通过简单的磁分离可循环利用,具有良好的循环使用性能。
英文摘要:
      Co-graphene composites were prepared by a simple one-step method using glucose as carbon source, NH4Cl as blowing agent and nano-metal Co as catalysts for promoting graphitization of glucose. The formation of graphene and the in-situ growth of Co nanoparticles are simultaneously performed. The structure and morphology of the composites were characterized by XRD, FTIR, XPS, Raman, UV-Visand and TEM. The composite was applied to catalytic reduction of p-nitrophenol (4-NP) and the results showed that 4-NP was completely reduced in 8 min using 4 mg catalyst at room temperature. It can be recycled by simple magnetic separation and has good cycle stability.
