Abstract
Control over the chemical composition and atomic ordering in bimetallic nanoparticles has driven the recent rapid progress in electrocatalysis. Liang & Yu [IUCrJ (2019), 6, 447-453] elucidate the structural differences between single metal and intermetallic multiply twinned decahedral nanoparticles on the example of AuCu particles and correlate the catalytic properties with their structure at the atomic level.
