MESOPOROUS NICKEL POWDER AND PREPARATION METHOD THEREFOR, NICKEL-PHOSPHORUS CATALYST SYSTEM AND ADIPONITRILE PREPARATION METHOD

WIPO Patent Application WO/2024/000734

A1

A mesoporous nickel powder and a preparation method therefor, and a nickel-phosphorus catalyst system. The mesoporous nickel powder comprises powder-like particles of metallic nickel, the average particle size of the particles being 1-100 μm, the average pore diameter being 10-60 nm, the pore volume being 0.02-0.09 cm3/g, and the BET specific surface area being 5.0-40.0 m2/g. The preparation method for the mesoporous nickel powder comprises: a hydrothermal synthesis step; a templating agent removal step; and a reduction step; the templating agent is a triblock copolymer comprising an A-B-A structure, or a disulfide bond diblock copolymer comprising an A-S-S-B structure. The nickel-phosphorus catalyst system comprises a complex formed by the mesoporous nickel powder and a phosphorus ligand.
