Ammonia, NH 3, is an alkaline gas and so turns damp red litmus ... by heating a solution of the ions with sodium hydroxide. This reaction produces ammonia gas, as shown in the ionic equation ...

Conventional catalysts, such as iron and ruthenium, rely on these harsh conditions to drive the reaction ... catalyst for ammonia synthesis even in the absence of any transition metal sites.

When the alkali metals are cut, they initially appear shiny grey but quickly become dull and white as they react with oxygen in the air. This is known as tarnishing. Sodium tarnishes more quickly ...

Researchers in South Korea have developed a cobalt-iron (CoFe)-based non-noble metal ammonia decomposition ... the highest efficiency in this reaction, but their high cost and the need for ...
