Immobolized organometallic catalyst and application of same

A method, comprising:

• preparing a catalyst having a plurality of amphiphiles;
• and
• decomposing hydrogen sulfide to produce hydrogen using the catalyst,
• wherein
• each of the amphiphiles comprises a polar head and a non-polar tail;
• at least a portion of the amphiphiles are functionalized amphiphiles;
• each of the functionalized amphiphiles comprises a catalytic center coupled to the polar head;
• and
• the catalytic center is disposed at an internal hydrophilic environment, which is encapsulated within a hydrophobic shell formed by the non-polar tails of the amphiphiles,
• wherein
• the catalytic center comprises an organometallic compound, and
• the organometallic compound comprises a dimethyl palladium(II) and a nitrogen-containing ligand.
