摘　　要：通过浸渍法获得负载氧化铜的硅基介孔分子筛催化剂。通过XRD、TEM等手段对所合成的样品进行表征,并评价了所合成的催化剂在选择性氧化DMM合成DMC过程中的催化活性。研究结果表明:氧化铜为该探针反应的有效活性组分,其负载于硅基介孔分子筛所制备的催化剂与NHPI具有协同催化的效果。Silicon-based molecular sieves supported copper oxide catalysts were prepared via immersion process. The catalysts were characterized by XRD and TEM techniques. The catalytic activity of prepared catalysts were evaluated in the synthesis of DMC by selective oxidation DMM. The results showed that Cu species was effective active components in synthesis of DMC by selective oxidation DMM, and that the synergetic effect between NHPI and silicon-based molecular sieves supported copper oxide catalysts accelerated the selective oxidation of DMM to DMC.
