Abstract
Carbon monolith-supported catalysts with high leach resistance used in catalytic applications involving strong acidic and basic conditions in a pH range of from 0 to 6.5 and from 7.5 to 14, are respectively described. The leach resistance of the catalyst system originates from strong interaction between the catalyst and the unsaturated valence of the carbon surface. In addition to surprisingly high resistance to leach out, the catalysts also have substantial differential advantages in catalyst performance: catalyst activity, selectivity, and stability.
