【摘要】：正六方密堆积(hcp)和立方密堆积(fcc)是金属晶体最常见的两种堆积方式,对于贵金属(金、银、钌、铑、钯、锇、铱、铂)晶体,除了钌和锇是hcp堆积外,其它最稳定的晶相均为fcc。而材料的不同晶相由于其不同的原子排列方式而具有迥异的物理化学性质,发掘材料新的晶相可以为探索高性能催化剂提供新的实践途径~1。目前,对于贵金属及其合金纳米材料晶相的调控主要采取高温、高压等比较苛刻的合成条件~2以及模板诱导的方
[Abstract]:(hcp) and (fcc) are the two most common stacking methods in metal crystals. For precious metal crystals (gold, silver, ruthenium, rhodium, palladium, osmium, iridium, platinum), except ruthenium and osmium are hcp stacking. The other most stable crystalline phases are all fcc. The different crystalline phases of the materials have different physicochemical properties because of their different atomic arrangement. Exploring the new crystalline phases of the materials can provide a new practical way to explore high performance catalysts ~ 1. At present, the crystal phase of noble metal and its alloy nanomaterials is mainly controlled by high temperature, high pressure and other harsh synthesis conditions ~ 2 and template-induced square.
