摘要：
在电解水产氢反应（HER）中,为了替代传统使用的价格高昂的铂基催化剂,开发含量丰富、高效的非贵金属催化剂是近年来的研究热点.其中,二硫化钼（MoS2）由于其低廉的成本和良好的活性受到了广泛的关注.目前,大多数报导均使用水热法合成MoS2,很少使用固相法.本文,我们使用一种钼基金属有机框架作为牺牲模板,通过一步高温固相合成得到尺寸均匀的MoS2纳米棒.所得棒状形貌能够有效暴露MoS2边缘活性位点,提升HER活性.同时,固相合成后,材料中仍有少量碳残留,这些残余的碳提升了催化剂的导电性,加速了HER过程中的电子转移,提升了催化剂的反应活性.因此我们合成的MoS2纳米棒表现出优异的HER性能,拥有很小的起始电位（96 mV）以及很低的塔菲尔斜率(93 mV dec-1).本工作为固相合成基于MoS2的复合材料提供了一种新的思路.
