Abstract
Hollow Ru nanoparticles with ~14 nm diameter and ~2 nm shell thickness are reported for the first time, by removal of Ni from the delicately designed Ni@Ru core@shell NPs. Such hollow Ru NPs exhibit enhanced catalytic activity in the dehydrogenation of ammonia borane with respect to solid ones.
摘要
首次报道了具有约 14nm 直径和约 2nm 壳厚的空心 Ru 纳米粒子，通过从精心设计的 Ni@Ru 核壳 NPs 中去除 Ni 得到。与实心 NPs 相比，这种空心 Ru NPs 在氨硼烷脱氢反应中表现出增强的催化活性。
