Recently, pentlandite materials have been shown to exhibit promising properties with respect to the hydrogen evolution reaction (HER). A whole series of trimetallic FeCoNi-pentlandite materials and composites have been synthesized from the elements using high-temperature synthesis and categorized in terms of purity. Furthermore, the electrocatalytic properties regarding the HER were determined and correlated to hydrogen adsorption energies, which were determined by means of density functional theory (DFT) calculations. The relationships between activity and its origin generated in this way help to better understand the pentlandite system and provide meaningful approaches for catalyst synthesis.
最近，已表明镍黄铁矿材料在析氢反应（HER）方面展现出有前景的性能。使用高温合成法由元素合成了一整套三金属FeCoNi-镍黄铁矿材料及复合材料，并根据纯度进行了分类。此外，测定了关于HER的电催化性能，并将其与通过密度泛函理论（DFT）计算确定的氢吸附能相关联。以这种方式产生的活性与其起源之间的关系有助于更好地理解镍黄铁矿体系，并为催化剂合成提供有意义的方法。
