Difference between nickel catalyst and Raney nickel catalyst

Yes, the Raney nickel catalyst is different from simple, fine nickel powder. Raney nickel is prepared in two steps. First, the nickel is alloyed with aluminum and then in second step much of the aluminum is removed through a leaching process with sodium hydroxide.
