On April 27 the on-line journal Science Advances published “Carbon-free H2 production from ammonia triggered at room temperature with an acidic RuO2/γ-Al2O3 catalyst.” The lead author, Katsutoshi Nagaoka, and his six co-authors are associated with the Department of Applied Chemistry at Oita University in Japan. The innovation featured in the paper could prove to be an important enabler of ammonia fuel in automotive applications.
