Abstract: A novel nickel particulate form is provided that efficiently forms a zero-valent nickel complex with a phosphorus-containing ligands in an organic liquid to form a hydrocyanation catalyst. Particles in the nickel particulate form comprise nickel crystallites. For example, the nickel particulate form can have a BET Specific Surface Area of at least about 1 m2/gm; an average crystallite size less than about 20-25 nm, the nickel particulate form can have at least 10% of the crystallites in the nickel form can have a diameter (C10) of less than about 10 nm, and/or there are on average at least about 1015 surface crystallites per gram nickel. A ratio of BET SSA to C50 for the nickel particulate form can be at least about 0.1×109 m/gm and preferably at least about 0.4×109 m/gm. Methods of preparation and use are also provided.
