Promotion effects of different methods in CO_x-free hydrogen production from ammonia decomposition

Abstract

Ammonia can be decomposed to produce exclusively hydrogen and nitrogen, so that it could function as a means for hydrogen storage. In situ hydrogen production from ammonia decomposition can effectively...

Potassium-promoted Ru-MCM-41 catalyst via in situ loading for effective low-temperature ammonia decomposition

“…Ammonia is a prospective hydrogen storage medium and carrier. 1–3 Compared with steam reforming, 4,5 dry reforming, 6,7 methane decomposition, 8–12 and biogas decomposition, 13 ammonia provides important benefits such as high density, cheap cost, 14–17 zero carbon emissions, 18,19 and an established production-supply-marketing chain, laying the groundwork for the development of ammonia energy. With the advancement of ammonia research in ammonia fuel cells, 18–20 there is an urgent need for low-temperature, efficient catalysts for hydrogen production from ammonia decomposition.…”
