层状过渡金属硫族化物（TMD）纳米材料在电催化析氢反应（HER）中已成为贵金属的极具潜力的替代催化剂。然而，目前的层状TMDs家族主要局限于IV-VII族过渡金属，而其他族金属基层状TMDs的合成仍然是一个挑战。


       鉴于此，武汉大学的罗威教授课题组首次利用原子分辨透射电子显微镜证实了通过简单的自下而上胶体合成方法，可以成功得到具有2H和1T混合相的六方RuSe2（h-RuSe2）纳米片，可以实现高活性HER电催化，这个RuSe2纳米片是层状TMDs家族中的一个新成员。
       本文要点：
      1) 研究人员以Ru(acac)3和Se粉为原料，在油胺溶液中成功地合成了h-RuSe2。所合成的h-RuSe2呈现出褶皱状的纳米片形貌，纳米片的直径约为40–70 nm。h-RuSe2纳米片主要是三角棱柱状的2H相，此外，除了2H相外，还观察到h-RuSe2纳米薄片的超薄1T相。纳米薄片呈六角形，直径约为70 nm，超薄纳米片处于八面体配位的1T相。
      2) 研究发现，h-RuSe2只有在经过600 °C退火后才能转变为立方RuSe2（c-RuSe2）的热力学有利相，h-RuSe2具有类Pt的电催化HER性能。实验结果和密度泛函理论（DFT）计算结果表明，H2O吸附自由能的提高、H的优化吸附自由能和h-RuSe的电导率的显著提高是导致h-RuSe2具有优异电催化HER活性的主要原因。

相比于质子交换膜燃料电池，阴离子交换膜燃料电池可以采用低成本的非Pt材料作为催化剂，因而备受关注。但是，发展在工况条件下具有高稳定性、低成本、高效的HOR催化剂是促进阴离子交换膜燃料电池商业化的关键。含有五种及以上的高熵合金（HEA）具有独特的原子构型和电子结构，因而有利于产生协同效应、可控的催化活性以及增强的结构稳定性。尽管已经开发了多种用于高效电催化的HEA，但是受到传统计算研究方法的限制，很难通过密度泛函理论（DFT）计算方法来直接研究复杂的HEA体系的基元反应的热力学吸附过程，因此阻碍了对催化机制的深入理解。
鉴于此，武汉大学罗威教授和陈胜利教授等人制备了PdNiRuIrRh HEA纳米颗粒，实现了优异的碱性HOR性能，并通过机器学习蒙特卡洛理论计算揭示了HEA的复杂原子分布和配位环境，从根本上理解了碱性HOR性能增强的起源。这项工作为HEA的原子结构和催化机制提供了重要的见解，并为开发先进的HOR电催化剂提供了新的思路。
本文要点：
1) 以预热的三甘醇为还原剂和溶剂，通过低温快速还原等摩尔量的五种金属前体实现了单相PdNiRuIrRh HEA纳米颗粒的简易制备，其中Pd/Ni/Ru/Ir/Rh的原子比为26.5/26.2/14.8/16.8/15.7；
2) 在0.1 M KOH电解质中，HEA电催化剂展现出超高的HOR质量活性，达到3.25 mA μg-1，分别是初始Pd、Ru、Rh、Ir和商业Pt/C的52、26、12、7和8倍，且优于大多数已报道的贵金属基催化剂，此外，该催化剂还表现出优异的抗CO毒化能力；
3) 通过机器学习蒙特卡洛理论计算，发现Pd-Pd-Ni/Pd-Pd-Pd成键环境和Ni/Ru亲氧位点能够改善*H的吸附/脱附并增强*OH吸附强度，因而显著增强了HEA的HOR活性和稳定性；
4) 结合循环伏安测试和机器学习电势模拟，阐明了HEA的催化活性主要源自于表面Pd和Ni的独特配位环境。
