Abstract: Disclosed herein are methods for manufacturing a catalyst composition. In one embodiment, a method for manufacturing a catalyst can comprise: forming a catalyst composition from a catalyst precursor and a volatile compound, disposing the catalyst composition on a substrate to form a supported composition, treating the supported composition with electromagnetic radiation, and removing at least a portion of the volatile compound to form the catalyst. In another embodiment, the method for manufacturing a catalyst can comprise: forming a catalyst composition comprising a volatile compound and a catalyst precursor, disposing the catalyst composition onto a substrate, and drying the catalyst composition at a temperature greater than or equal to a dew point of the volatile compound and less than or equal to a decomposition temperature of the catalyst precursor.

Abstract: A process for hydroxylating an aromatic compound comprises the steps of: (a) contacting an aromatic compound with a catalyst having an average concentration of .alpha.-sites of at least about 1.multidot.10.sup.16 per gram of catalyst, the catalyst having .alpha.-oxygen loaded thereon, whereby an hydroxylated derivative of the aromatic compound is produced; and (b) regenerating the catalyst when the concentration of .alpha.-sites falls below a predetermined value. The predetermined value will depend on the process design, but can suitably be about 1.multidot.10.sup.16 per gram of catalyst or higher.Another embodiment of the process comprises: (a) contacting an aromatic compound with a catalyst having an average concentration of .alpha.-sites of at least about 1.multidot.10.sup.16 per gram of catalyst, the catalyst having .alpha.-oxygen loaded thereon, whereby an hydroxylated derivative of the aromatic compound is produced; and (b) reloading the catalyst with .alpha.
