【摘要】 对硝基苯胺是极为重要的工业中间体,广泛应用于医药、农药、染料等领域。由此引起的环境污染引起了人们的密切关注,建立有效的监测和处理技术具有重要的现实意义。本文以Hummers法制备的氧化石墨为原料,尿素为氮源,采用一步水热法制备掺氮石墨烯-Ag纳米复合材料。借助石墨烯的独特二维平面结构,充分发挥Ag纳米粒子的催化性能,系统研究其对硝基苯胺的催化还原性能。结果显示,掺氮石墨烯(NG)-Ag纳米复合材料对硝基苯胺与硼氢化钠的反应有很好的催化效果,酸性或碱性环境都能加快反应进度,该反应在15min,转化率高达96%。更多还原

【Abstract】 In this paper, nitrogen doped graphene-Ag nanocomposites synthesized by hydrothermal method were used as catalyst to investigate catalytic performance toward the reduction of p-nitroaniline. The results show that the addition of nitrogen doped graphene-Ag nanocomposites in the reacting system can accelerate the reaction rate. The reducing efficiency is over 96% in 15 mintues. As a result, nitrogen doped graphene-Ag nanocomposites have potential applications in p-nitroaniline determination and treatment in waste water.更多还原
