Claim:
1. A heterogeneous hydrogenation catalyst, wherein the catalyst is selected from the group consisting of hexagonal boron nitride, substitutionally doped graphite, substitutionally doped carbon nitride, and an inorganic-organic hybrid material, the catalyst having: 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 sites, wherein the at least one frustrated pair of Lewis acid and Lewis base sites is catalytically active; wherein the Lewis acids of the inorganic-organic hybrid material are selected from the group consisting of Group 13 elements in a trigonal planar configuration, halides of Group 15 elements, electron poor π-systems, and combinations thereof, and wherein the Lewis bases of the inorganic-organic hybrid material are selected from the group consisting of simple anions, Group 15 and Group 16 lone-pair-containing species, complex anions, electron rich π-systems, and combinations thereof.
