一种制备银纳米颗粒修饰二氧化钛复合材料的方法
摘要：
本发明公开了一种制备银纳米颗粒修饰二氧化钛复合材料的方法，包括如下步骤：a.将二氧化钛加入硝酸银溶液中配制成悬浮液，在室温下搅拌均匀；b.将步骤a所得的悬浮液滴在透射电镜用碳膜支撑网上，自然晾干，获得样品支撑膜；c.将步骤b制备的样品支撑膜进行电子束辐照，控制辐照束流强度为50-150pA/nm2，得到银纳米颗粒修饰的二氧化钛复合材料。本发明的方法工艺简单、成本低，不使用有机溶剂且具有银纳米颗粒粒径可控的优点。
摘要（英）：

The invention discloses a method for a preparing silver nano particle modified titanium dioxide composite material. The method comprises the steps that a, titanium dioxide is added to a silver nitratesolution to be prepared into suspension and uniformly stirred at room temperature; b, the suspension obtained in step a is added to a carbon membrane supporting net for a transmission electron microscope dropwisely and naturally dried to obtain a sample supporting membrane; c, electron beam irradiation is conducted on the sample supporting membrane which is obtained in step b, the intensity of the irradiation beam is 50-150 pA/nm2, and therefore the silver nano particle modified titanium dioxide composite membrane material is obtained. The method has the advantages that the technology is simple, the cost is low, no organic solvent is used, and the particular diameter of the silver nano particle is controllable.
