Ammonia to Hydrogen (Ruthenium catalysis)

Ammonia to Hydrogen
Materials
Urea / Silica / Ruthenium
In a dropper to hold things in place. All in a larger glass tube to contain the hydrogen

The urea is heated to decomposition to ammonia( at temp. 180 °C)the ruthenium is then heated in (20% NH3 at 400°C)with a heat gun on the Ruthenium. Ammonia converts to hydrogen and this can be detected with a CO detector due to similarity of operation.

Was reluctant to destroy my ruthenium although I think ruthenium on Alumina is more effective.

Hydrogen production by ammonia decomposition is an in-situ technology that facilitates the storage and transportation of hydrogen. Due to its excellent catalytic performance, ruthenium is widely used as a catalyst for ammonia decomposition.

You got a source for that? Have you done this?

Not yet I'm getting all the correct materials

There's a Japanese startup hoping to make hay by running the reverse process, claiming that they can make an ammonia plant ten times smaller than existing ones. This would be an important technology for the "solar ammonia economy" so it has received a fair amount of research interest — the founder is a chemist.

Still, running the reaction uphill at home sounds pretty tough.
