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.
合成了成分略偏离等摩尔比的铂族金属五元RuRhPdIrPt合金纳米颗粒，并对其晶体结构和电子结构进行了研究。其晶格常数随成分呈线性变化，而d带中心呈非线性变化。它们对析氢反应的催化活性与d带中心无关。
