Abstract
Catalysts for producing one or more oxygenated products from methane are provided. In embodiments, the catalyst comprises active sites comprising isolated, cationic transition metal M′ atoms covalently bound to internal surfaces of pores of a porous metal M″ silicate, wherein M′ is Rh or Ir, and further wherein the M′ atoms are bound to five oxygen (O) atoms. Methods for making and using the catalysts are also provided.

A catalyst for producing one or more oxygenated products from methane, the catalyst comprising active sites comprising isolated, cationic transition metal M′ atoms covalently bound to internal surfaces of pores of a porous metal M″ silicate,
- wherein M′ is Rh or Ir, and
- further wherein the M′ atoms are bound to five oxygen (O) atoms.
A catalyst for producing one or more oxygenated products from methane, the catalyst comprising active sites comprising isolated, cationic transition metal M′ atoms covalently bound to internal surfaces of pores of a porous metal M″ silicate,
- wherein M′ is Rh or Ir,
- wherein the active sites have formula (O2 )=M′≡(O)3, wherein O2 is molecular oxygen and the remaining O atoms are covalently bound within the porous metal M″ silicate, and
- further wherein one, two, or all three of the oxygens of the M′≡(O)3 bonds are also covalently bound to the M″ of the porous metal M″ silicate, thereby providing one, two, or three M′-O-M″ linkages.
