| 摘 要： | 以自制的季铵盐型木质素为模板,用热分解法在钛板制备成铂涂层。SEM分析表明,不同条件下制备的铂涂层具有多种形态特点:颗粒堆垛、颗粒网络和颗粒密排的组织结构。添加不同含量的季铵盐型木质素,可以获得多级孔,甚至网络结构的铂多孔涂层。VPt∶Vlig=4∶5,铂微粒粘连形成了三维网络结构。采用500℃热处理显示出多样性的表面形态。400℃处理的样品具有较大面积的表面空洞区域,也有更加明显的网状多孔结构。

| Abstract: | Pt coatings were synthesized through thermal decomposition,using an aminated lignin as template.SEM results show that the prepared Pt coatings have different morphologies,such as pile-stacking,network-linking and close-packing.Addition of quaternary-ammonium-salt lignin porous Pt films with multi-stage or metwork structures can be obtained. If V_(Pt) : V_(lig) =4:5,Pt particles could form a 3D-network structure.Treated at 500 ℃,different types of morphologies are showed.The samples treated at 400 ℃ show larger porous surface area and more distinct network structure. |
