Pt 3 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. Pt 3 Co alloyed nanoparticles, illustrated as small planets in space, are synthesized from two different precursor spacecraft, MeCpPtMe 3 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 Pt 3 Co small planets releasing small spacecraft of by‐products (C 5 H 5 , CO 2 , CH 4 , and CH 3 ‐C 5 H 5 ). The astronauts perform post‐treatment for the perfectly alloyed structure, which corresponds to the thermal treatment in this study.
