Raney Nickel preparation and how to use it for catalytic Hydrogenation


So in ceramic cup, I plan to short circuit two Carbon electrodes at Nickel pieces (or powder) and expect the Aluminum piece benight to melt as well. After I powderize the alloy using abrasive stone rotated by electric motor, or crush the alloy using hammer, Do I expect a lot of Carbides formed and does these contaminants screw later the leaching process with NaOH(aq) ?
How do I check if the Raney Nickel prepared by this method is able to reduce Acetone to 2-HydrOxy Propane or Benzaldehyde to Phenyl Methyl Hydroxide. How to check if it does reduce 2-Nitro Propane into 2-Amino Propane, Please Help. Is this the balanced reaction that I need to do for making it catalitic ?
NiAL3+2NaOH+6H2O>NiAL+2NaAL(OH)4+3H2

at least you tried…

…but not enough.

EDIT: have someone take a spoon and feed it to you.

if it tastes like shit, you're spot on!

Do I smell cookery?

Either way, is this a valid prep for Raney Nickel? Can OP (or anyone) provide any refs?

OP is a drug cook and you will not get any reference out of him. He wishes to use an ark furnace to melt the metals into an alloy, and I can not see this being a great method. He has also not considered the inhibiter metal required to make the catalyst an active and ternary alloy. I wont say anymore here, I do not wish to contribute to this mans amphetamines production.

[...] to reduce Acetone to 2-HydrOxy Propane[...] --> why would you want to do this? Academic interest :P
[...] or Benzaldehyde to Phenyl Methyl Hydroxide [...] --> most people want it the other way around ;)
[...] reduce 2-Nitro Propane into 2-Amino Propane [...] --> and now we really smell the little devil :D

Little devils have no place here, they usually are transferred to detritus. This one is no exception.
