Abstract
Monodisperse 4 nm AuPd alloy nanoparticles with controlled composition were synthesized by co-reduction of hydrogen tetrachloroaurate(III) hydrate and palladium(II) acetylacetonate with a borane-morpholine complex in oleylamine. These NPs showed high activity (TOF = 230 h(-1)) and stability in catalyzing formic acid dehydrogenation and hydrogen production in water at 50 °C without any additives.
摘要
通过在油胺中使用硼烷-吗啉配合物共还原水合四氯金酸(III)和乙酰丙酮钯(II)，合成了具有可控组成的单分散 4nmAuPd 合金纳米粒子。这些 NPs 在 50°C 下无需任何添加剂在催化甲酸脱氢和水制氢反应中表现出高活性（TOF=230h(-1)）和稳定性。
