技术领域
本发明涉及一种Te-Pd核壳纳米线的制备方法，具体涉及一种一维连续的Te-Pd核壳纳米线的制备方法。
背景技术
贵金属催化剂由于其无可替代的催化活性和选择性,在炼油、石油化工和有机合成中占有极其重要的地位。贵金属钯具有优异的催化性能，钯催化剂在石油化学工业中的应用广泛。在很多有机合成反应中，钯是优良的催化剂，或是催化剂的重要组分之一。然而催化活性低,且催化剂难以分离回收和重复使用这些因素严重影响了钯催化剂的应用。开发高活性、高选择性的钯催化剂也是研究热点。钯催化剂结构,不仅决定其催化活性,而且决定其在反应结束后是否可通过简单的过滤实现催化剂的回收利用。钯基核壳纳米材料通过对钯催化剂中组分的改进,可提高催化剂的活性及选择性。
发明内容
本发明的目的在于提供一种一维连续的Te-Pd核壳纳米线的制备方法，该方法通过光催化法在碲细纳米线的表面负载一层钯纳米粒子。随后经过干燥后，即可得到了尺寸均一，直径约5纳米的一维连续Te-Pd核壳纳米线。
为实现上述目的，本发明采用的技术方案是：一种一维连续的Te-Pd核壳纳米线的制备方法，包括以下步骤：
1)按质量份数，称取5-10份的碲细纳米线加入到含有25-50份无水乙醇的烧杯中，磁力搅拌30-50分钟使得分散均匀；
2)取步骤1)中的分散溶液，以碲、钯原子摩尔比为3：(1-10)的比例加入四氯钯酸钠Na2PdCl4，分散到乙醇和超纯水各50％的混合溶液中，N2曝气，紫外光源下照射反应4-6小时，即得Te-Pd核壳纳米线成品。
与现有技术相比，本发明具有以下有益效果：
1.本发明通过在碲细纳米线表面负载一层铂纳米粒子，形成核壳结构。然后经过离心洗涤、干燥即可得到一维连续的Te-Pd核壳纳米线。微观状态下Te-Pd核壳纳米线相互交织在一起；
2.本发明制备出一维连续的Te-Pd核壳纳米线材料活性面积大，催化活性高；
3.本发明制备过程简单，条件易于控制，便于规模生产。
