8. Electrified dynamically responsive ammonia decomposition to hydrogen based on magnetic heating of a Ru nanocatalystŽiga Ponikvar, Anja Sedminek, Janvit Teržan, Luka Skubic, Žan Lavrič, Matej Huš, Miha Grilc, Blaž Likozar, Darko Makovec, Sašo Gyergyek, 2024, izvirni znanstveni članek Povzetek: Storing and transporting pressurized or liquid hydrogen is expensive and hazardous. As a result, safer methods, such as chemical storage in ammonia, are becoming increasingly important. However, the instantaneous start of a conventionally heated decomposition reactor is challenging. Here we report on the electrified and dynamically responsive decomposition of ammonia as a means of releasing on-demand chemically bonded hydrogen based on the rapid magnetic heating of a well-designed Ru-based nanocomposite catalyst. Under relatively mild conditions (400 °C, 1 bar) a rapid decomposition rate of 5.33 molNH3 gRu-1 h-1 was achieved. Experimental observations under non-isothermal, dynamic conditions coupled with modelling at the level of density functional theory and micro-kinetic modeling confirmed the minute-scale response of the H2 release. The rapid response of our catalytic system would, at least in principle, enable the utilization of intermittent, renewable electricity and a tunable H2/NH3 ratio in the reactor’s effluent.
