Abstract Nickel is a promising candidate as an alternative to ruthenium for ammonia decomposition catalyst. However, the performance of Ni‐based catalysts still not sufficient achieve good hydrogen production rate under low‐temperature because weak nitrogen affinity Ni reduces frequency reaction. Here, it reported that supported on barium titanium oxynitride (Ni/ h ‐BaTiO 3− x N y ) with hexagonal structure acts highly active and water‐durable catalyst decomposition. The operation...
Nitrogen vacancies formed on NaCl-type binary transition metal nitrides and ammonia decomposition activity employing as supports can be understood in terms of the ionic radii cations.
Transition metals play a crucial role as catalysts in artificial ammonia synthesis. Ruthenium (Ru) stands out the most active metal, but its industrial application is constrained due to natural scarcity and hydrogen poisoning at low temperatures. Cobalt (Co) has been extensively studied more cost-efficient non-noble metal catalyst. However, goal of high-performance, air-durable Co catalyst not reached date. The obstacle this study lies inherent weak Co–N interaction use atmospherically...
