Herein a facile and versatile hydrothermal method has been developed to construct a polypyrrole-derived carbon nanotube (PCN), MoS2 nanosheets and a carbon shell integrated sandwich-like heterostructure (PCN@MoS2@C). This heterostructure shows excellent performance in the hydrogen evolution reaction (HER) over a wide pH range. The results indicate that the porous carbon shell coated heterostructure provides MoS2 nanosheets with sufficient conductivity, increased number of active sites, and strong structural stability, and thus boosts its HER performance.
在此，我们开发了一种简便且通用的水热法来构建聚吡咯衍生的碳纳米管（PCN）、二硫化钼纳米片和碳壳集成的三明治状异质结构（PCN@MoS2@C）。这种异质结构在很宽的pH范围内的析氢反应（HER）中表现出优异的性能。结果表明，涂覆有多孔碳壳的异质结构为二硫化钼纳米片提供了足够的导电性、增加的活性位点数量和强大的结构稳定性，从而提高了其析氢反应性能。
