Abstract

Trisegmented Au-Ru-Au and Ru-Au-Ru nanorods catalyze the decomposition of hydrogen peroxide, pumping fluid along their axis as "pullers" and "pushers" respectively. Numerical simulations and experiments with passive tracer particles show that catalytically generated hydrodynamic and electrostatic forces both contribute to pairwise and collective particle assembly.

摘要

三段式金-钌-金和钌-金-钌纳米棒催化过氧化氢的分解，分别作为“拉引器”和“推动器”沿其轴泵送流体。对被动示踪粒子的数值模拟和实验表明，催化产生的流体动力和静电力都有助于粒子的成对和集体组装。
