Description
技术领域
本发明属于燃料电池催化剂的制备领域，具体为一种二维层状材料黑磷烯包覆贵金属催化剂的核壳结构燃料电池催化剂。
背景技术
质子交换膜燃料电池以氢气为燃料、氧气（空气）为氧化剂，具有高功率、工作温度低、低污染甚至零污染等优点，被公认为理想的洁净能源。但氢气和氧气（空气）中存在二氧化硫等杂质气体，会毒化铂基催化剂，使得电池的性能大幅下降甚至失效。因而提高质子交换膜燃料电池催化剂抗二氧化硫中毒性能，是保障电池性能、提高电池稳定性的重要途径。
二氧化硫分子在铂表面的吸附能低于氢，会抢先占据铂表面并阻碍氢在铂表面的吸附。因而提高催化剂抗二氧化硫中毒性能，可以通过提高催化剂对二氧化硫的氧化能力，亦可通过降低二氧化硫在催化剂表面的吸附而实现。黑磷烯是一种二维材料，可沉积于催化剂表面形成保护层，阻碍二氧化硫在催化剂表面的吸附；同时由于其具有多元环状结构，可保障氢的顺利通过并吸附于催化剂表面而发生氧化反应。
发明内容
本发明目的旨在提供一种具有抗二氧化硫中毒性能的质子交换膜燃料电池催化剂及其制备方法。
实现上述目的的方案为：
一种核壳结构的质子交换膜燃料电池催化剂，所述催化剂为二维层状材料黑磷烯包覆的贵金属，催化剂的颗粒尺寸为1~100 nm。
贵金属的质量分数9~90%，黑磷烯的质量分数为10~91%，二者质量分数和为100%。
所述黑磷烯是以红磷为原料制备而成，其层数为1~20层。
贵金属为金、银、铂、钌、铑、钯、锇、铱中的一种或几种。
制备方法包括如下具体步骤：
1）将贵金属与红磷混合并在保护气氛下烘干；
2）将步骤1）所得贵金属与红磷的混合物研磨；
3）将步骤2）所得研磨后的混合物置于管式炉中，在保护气氛下升温至500~800°C并保温2~4小时，而后降温至300~400 °C并保温2~4小时，最后冷却得到所述的核壳结构的质子交换膜燃料电池催化剂。
步骤1）和步骤3）中所述的保护气氛是氮气、氩气、氦气中的一种或氮气、氩气、氦气任意体积比的混合气体。
本发明的有益效果在于：
本发明通过在金属催化剂表面形成黑磷烯保护层，阻碍二氧化硫在催化剂表面的吸附，同时由于黑磷烯保护层具有多元环状结构，可保障氢的顺利通过并吸附于催化剂表面而发生氧化反应，使得催化剂在确保其催化性能的同时具有良好的抗二氧化硫中毒性能，能够提高燃料电池的稳定性能及寿命。
附图说明
图1为实施例1制得的催化剂的二氧化硫电化学氧化性能曲线。
将实施例1所制备的P@Pt催化剂做二氧化硫电化学氧化实验并与Pt/C催化剂做对比，结果显示催化剂在1.2 V 均出现了二氧化硫的氧化峰。但P@Pt催化剂的峰值明显比Pt/C催化剂小，说明P@Pt催化剂中Pt表面所吸附的二氧化硫少于Pt/C催化剂，即P@Pt催化剂具有较好的抗二氧化硫中毒的性能。

实施例2
1）将钯催化剂与红磷混合并在氦气气氛下烘干，其中铂颗粒的尺寸为100 nm；
