Hydrogen gas as a reducing agent?

inertia - 25-6-2014 at 09:40

I'm looking to use H2 gas as a weak/mild reducing agent on par with sodium cyanoborohydride. I understand that a metal catalyst is required, and from some literature I've read, high pressure is also key. Is it feasible to use hydrogen as a reducing agent in a home lab setting, and what would a set up for this look like? If it's not feasible, is there something an amateur chemist could acquire similar to NaBH3CN? Thanks

In mild conditions of temperature and pressure hydrogen is a very sluggish species and will not behave remotely like NaBH3CN or NaBH4. Various Ni/Pt/Pd based catalysts can help these hydrogenations along nicely.

What is it precisely you're trying to reduce?
