Hi,
Exist there for a catalysis of hydrogenation another metal with the characteristics of palladium even if other metals do not generate as much
hydrogen
The Tungsten can it replace it! Or gold, silver,or other ?
Regards.

Raney nickel?

It depends what you want to do.
Ni is a fairly good hydrogenation catalyst.

Nickel can be made a hell of a hydrogenation catalyst - all sugar reductions for example are done with those. Just heating precipated Ni at 800°C
under a stream of hydrogen is fairly out of reach I fear.
There had been rumors on tungstencarbide having similar properties to Pd/Pt, but I never heard something on this again.
Catalytic hydrogenation is art. This is by no way easy to do - with or without pressure.
Hum... . .

Thank you for all information I will look at the track of the tungstencarbide !
