I have one bottle of 50 mesh copper powder, 96%.(non-activated)
How can I get activated copper powder from that?
Any suggestions?
Thank you very much.

That really depends on the sense in which you mean "activated," you're using something like jargon, even if its scientifically apt. A quick Google leads to this reference: http://pubs.acs.org/doi/abs/10.1021/jo01333a050 So if you mean in that sense, highly reactive nano-szised copper particles, then you want to do it the way the reference says.

I intend to dimerize the 2,5-dibromonitrobenzene.
According to
http://www.worldscientific.com/doi/abs/10.1142/S025676790800287X
Activated copper powder is needed.
Can I use the copper powder that I have or I need to synthesize the highly reactive nano-sized copper particles as this reference?

I 'm not sure, but maybe some of our organic chemistry experts can help you. As another example, here's a reference for a Suzuki cross-coupling using activated copper powder: http://pubs.acs.org/doi/abs/10.1021/cm040142i?src=recsys&journalCode=cmatex
I don't know what "activation" means in these references, in the context of the reactions in question. I assumed it wasn't possible to just grind up some copper powder. But here's a reference where that is exactly the case: http://link.springer.com/article/10.1007/s10789-005-0029-9
