Core–shell structured microcapsular-like Ru@SiO2 reactor for efficient generation of COx-free hydrogen through ammonia decomposition

The core–shell structured microcapsular-like Ru@SiO2 reactor is proved to be the most efficient material known to date for COx-free hydrogen production via ammonia decomposition for fuel cells application. The very active Ru core particles can retain good stability even at high temperatures (up to 650 °C) thanks to the protection of the inert SiO2 nano-shell.
