合成了铂族金属五元RuRhPdIrPt合金纳米粒子，其组成略偏离等摩尔，并对其晶体结构和电子结构进行了研究。它们的晶格常数随组成呈线性变化，而d带中心呈非线性变化。它们对析氢反应的催化活性与它们的d-带中心无关。
Platinum-group-metal quinary RuRhPdIrPt alloy nanoparticles were synthesised with compositions slightly away from equimolar, and their crystal and electronic structures were investigated. Their lattice constant changed linearly with composition, while the d-band centre changed nonlinearly. Their catalytic activities for the hydrogen evolution reaction were not correlated with their d-band centre.
