Core-shell structured microcapsular-like Ru@SiO2 reactor for efficient generation of CO(x)-free hydrogen through ammonia decomposition.

The core-shell structured microcapsular-like Ru@SiO(2) reactor is proved to be the most efficient material known to date for CO(x)-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 degrees C) thanks to the protection of the inert SiO(2) nano-shell.
