Please, provide me with examples of organic/inorganic materials having the next features:
1. Solid-state porous structure or framework, compound with the high specific surface area.
2. Surface, covered with chemically bonded hydrogen (not physically adsorbed).
3. The hydrogen should be extracted from the surface by way of chemical reaction without destruction of the porous composition.
The examples of common porous hydrides, organic frameworks and other like hydrogen-containing solid-state compounds are suitable. Also, their chemical properties, the ways of hydrogenation/dehydrogenation are under interest.
I can recommend activated sponge Titanium which may chemosorbe really 1,9% of H2. I think more easy way is to use titanium hydride which after high temperature ( about 600) decomposition ( activation) and evacuation can adsorb H2
best regards
The hydride technologies - gaseous H2 absorption and then desorption by heating - are well known. But something else is under interest:
What are the ways of their hydrogenation using liquid reactants?
For example, silicon etched in HF solution becomes porous material with the hydrogen-covered surface. Refreshing of aged porous silicon in HF increases its hydrogen content. I will be pleased for the something like examples.
There are some polyoxometalates which has chemically bonded hydrogen at surface.
