Abstract
The inventive concepts disclosed and/or claimed herein relate generally to catalysts and, more particularly, but not by way of limitation, to a heterogeneous, metal-free hydrogenation catalyst containing frustrated Lewis pairs. In one non-limiting embodiment, the heterogeneous, metal-free catalyst comprises hexagonal boron nitride (h-BN) having frustrated Lewis pairs therein.
Claims38
A heterogeneous hydrogenation catalyst, comprising:
- a solid surface substantially free of metals, the solid surface having at least one Lewis acid site and at least one Lewis base site;
- and
- at least one defect frustrating at least one pair of Lewis acid and Lewis base site sites, wherein the at least one frustrated pair of Lewis acid and Lewis base sites is catalytically active.
A heterogeneous hydrogenation catalyst, comprising:
- a solid surface having non-metallic Lewis acid moieties and non-metallic Lewis base moieties spaced a distance apart from one another such that (a) catalytic activity is present therebetween and (b) the formation of an acid-base adduct is prevented.
A heterogeneous hydrogenation catalyst, comprising:
- a sheet of catalytically active material substantially free of metals having unsatisfied Lewis acid-base pairs along a surface of the sheet.
(canceled)
The heterogeneous hydrogenation catalyst of claim, wherein the catalyst is capable of catalytically hydrogenating an alkene.
A method of making a hydrogenation catalyst, comprising:
- mechanically processing hexagonal boron nitride in the presence of an alkali metal element or hydrogen to produce a catalytically active defect on a surface of the hexagonal boron nitride.
(canceled)
(canceled)
A hydrogenation process comprising:
- contacting a hydrogenatable compound with hydrogen gas and a catalyst in a reactor, wherein the catalyst comprises a solid material having frustrated Lewis pairs;
- and
- catalytically hydrogenating the hydrogenatable compound.
