Abstract
An active component carrier composition is disclosed comprising a mixture of one or more catalytically active components and one or more oxidized disulfide oil (ODSO) compounds, including a water-soluble fraction of ODSO. In certain embodiments the ODSO is obtained from the effluent of an enhanced MEROX process. The active component carrier composition facilitates transfer of catalytically active components (or components that will be catalytically active in the finished solid catalyst material) onto the surface of support materials.

The method of claim 14, comprising 0.01-5 percent by mass of the one or more catalytically active components.
The method of claim 14, wherein the active component carrier composition is in an aqueous solution.
The method of claim 14, wherein the active component carrier composition further comprises one or more additional acidic components.
A method for synthesis of a material comprising:
- forming a homogeneous aqueous mixture of precursors, reagents and an effective amount of an active component carrier comprising a mixture of one or more catalytically active components and one or more oxidized disulfide oil (ODSO) compound ;
- heating the homogeneous aqueous mixture under conditions and for a time effective to form solids as precipitate suspended in a supernatant as an intermediate suspension, wherein the precipitate comprises the synthesized material which contains one or more catalytically active components transferred from the active component carrier composition.
