10 Claims

1. A method for preparing a material for degrading organo halogen compounds (OHC's), the method comprising:

preparing an aqueous solution of oleic acid and iron ions;

preparing an aqueous solution of oleic acid and palladium ions;

combining the aqueous solution having iron ions with the aqueous solution having palladium ions and form nanosized micelles having lipophilic terminal surfaces;

providing carbonaceous material having mesopores;

combining the nanosized micelles with the carbonaceous material to form a precursor material;

heating the precursor material in the presence of air or oxygen to form precursor oxide material;

reducing the precursor oxide material to form the material for degrading OHC's;

whereby after the combining of the solutions, the combined solutions are allowed to rest for a time period within a range of from 1 h to 24 h to form the nanosized micelles.
