Dicationic particles in the form of cappoly(4-vinyl pyridine)(++)-1,4-butane (cap-p(4-VP)(++)-C-4), capsule-poly(4-vinyl pyridine)(++)-1,6-hexane (cap-p(4-VP)(++)-C-6), and capsule-poly(4-vinyl pyridine)(++)-1,8-octane (cap-p(4-VP)-C-8) were prepared by modifying cap-p(4-VP) particles with corresponding dibromo alkanes. Then, polymer-metal composites were also prepared from cap-p(4-VP) and dicationic cap-p(4-VP) particles by loading CoCl2 from ethanol and the obtained composites were used in H-2 generation from hydrolysis of NaBH4, and The Ea for the composite catalyst was calculated as 56.53 kJ/mol.
