银/凹凸棒土纳米复合材料的制备与表征

Preparation and Characterization of Attapulgite/Silver Nanocomposites

通过一种新颖而简单的方法,成功地制备了银/凹凸棒土纳米复合材料.巯基功能团对纳米凹凸棒土的表面修饰是重要步骤.TEM和AFM观察表明,银纳米粒子在凹土棒晶上呈线形沉积,类似于纳米线的形态,这在抗静电性及催化反应方面的应用具有很大价值.

We report on the successful preparation of silver-attapulgite nanocomposites by a novel and simple method. It is important step, which is mercapto functionalizing the surface nano-attapulgite via hydrolyze of MPTS. TEM and AFM morphology observation showed that the silver nanoparticle is not saturate in the rod like crystal of nanoattapulgires, but is deposition On surface of the nanoattapulgites. It is similar to nanowire state. The attapulgite-Ag nanocompostes are potentially useful for carrier catalyst and electric material.
