Abstract
Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and a supported transition metal catalyst—containing molybdenum, tungsten, or vanadium—are irradiated with a light beam at a wavelength in the UV-visible spectrum, optionally in an oxidizing atmosphere, to form a reduced transition metal catalyst, followed by hydrolyzing the reduced transition metal catalyst to form a reaction product containing the alcohol compound and/or the carbonyl compound.

A supported transition metal catalyst comprising:
- a solid support;
- and
- from 0.01 to 50 wt. % of a transition metal comprising molybdenum, tungsten, vanadium, or a combination thereof, based on the weight of the catalyst;
- wherein:
- at least one bonding site on the transition metal has a ligand characterized by the following formula:
- —O-Hydrocarbon group;
- and
- a molar ratio of the hydrocarbon group to transition metal is in a range from 0.25:1 to 2:1.
A supported transition metal catalyst comprising:
- a solid support;
- and
- from 0.1 to 5 wt. % of a transition metal comprising molybdenum, tungsten, vanadium, or a combination thereof, based on the weight of the catalyst;
- wherein:
- at least one bonding site on the transition metal has a ligand characterized by one of the following formulas:
- —O-Hydrocarbon group or —O-Halogenated hydrocarbon group.
A supported transition metal catalyst comprising:
