We first report the synthesis of B2-structured indium-platinum group metal high-entropy intermetallic nanoparticles (In-PGM HEI NPs). The synthesis was achieved by a wet-chemistry method and subsequent heat treatment. The crystal structure of these NPs is unique in the coexistence of completely orderly arranged indium and disorderly arranged PGMs.
