Abstract

Abstract : The cover represents the different morphologies (bowls, rattles, and dendrites) in metal/metal‐oxide bimetallic nanoparticles, as demonstrated in article1700175 by Camargo and co‐workers. They were produced from Cu2 O spheres (depicted in the center) as templates in a galvanic replacement reaction with PdCl4 2−, AuCl4 − or Ru 3+ . The formation of each morphology is controlled by the reduction kinetics of each metal precursor during synthesis.
