Description

金属纳米簇催化剂的制备方法
技术领域
本发明涉及一种金属纳米簇催化剂的制备方法。
背景技术
金属纳米簇是由一定数量的金属原子按一定的方式堆积而成的纳米级金属颗粒,结构包括球状、线状、棒状等各种形态,尺寸介于1~50nm,是不同于原子(分子)也不同于块状物质的新体系,具有高比表面积、小尺寸效应、表面缺陷效应等特性。
金属纳米簇非常活泼,具有很好的催化性能,作为一类新型催化剂广泛用于氢化反应、氧化反应、Heck反应等反应体系。
但金属纳米簇粒子最大的问题是不稳定,易于聚集,导致其颗粒尺寸变大,进而影响其催化性能。
发明内容
本发明需要解决的技术问题就在于提供一种金属纳米簇催化剂的制备方法,它通过液相还原法制备金属纳米簇催化剂,具有设备简单、尺寸可控等优点。
为解决上述问题,本发明采用如下技术方案:
本发明一种金属纳米簇催化剂的制备方法,所述方法为高温液相还原法,以四水醋酸钴为金属前驱体盐、十二烷二醇为还原剂,利用表面活性剂油酸和三辛基磷(top)包裹金属表面,合成出单分散的球形、自组装成有序的2d结构磁性金属纳米晶钴。
液相还原法是常用的制备金属纳米簇的方法,具有设备简单、尺寸可控等优点。通过该法在含有稳定剂的不同介质(有机介质或水溶液)中,用还原剂对金属盐进行还原可得到金属纳米簇。
具体实施方式
采用高温液相还原法,以四水醋酸钴为金属前驱体盐、十二烷二醇为还原剂,利用表面活性剂油酸和三辛基磷(top)包裹金属表面,合成出单分散的球形、自组装成有序的2d结构磁性金属纳米晶钴。
最后应说明的是:显然,上述实施例仅仅是为清楚地说明本发明所作的举例,而并非对实施方式的限定。对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的显而易见的变化或变动仍处于本发明的保护范围之中。
