Advances in Gaseous Ammonia Decomposition for Hydrogen Production: Catalysts and Emerging Pathways
Ammonia (NH3) is a compelling carbon-free hydrogen carrier. Its catalytic decomposition to produce a hydrogen/nitrogen (H2/N2) gas stream is central to the “NH3-H2” clean energy cycle, provided that residual NH3 is removed to fuel-cell-grade purity downstream. This review integrates advances from the past five years ac...
