Abstract

Abstract : Pt3 Co nanoparticles synthesized by the one‐pot chemical vapor deposition (CVD) technique, described by S. O. Kim, H. Kim and co‐workers on page 7115. Pt3 Co alloyed nanoparticles, illustrated as small planets in space, are synthesized from two different precursor spacecraft, MeCpPtMe3 and CpCo(CO)2 . In the image, the silver spheres signify Pt atoms, and the blue spheres represent Co atoms. After both precursor spacecraft land on a carbonaceous planet, they are decomposed and made into Pt3 Co small planets releasing small spacecraft of by‐products (C5 H5, CO2, CH4, and CH3 ‐C5 H5 ). The astronauts perform post‐treatment for the perfectly alloyed structure, which corresponds to the thermal treatment in this study.
