N2 - Physicochemical study of cis-[Pt(NH3)2Cl2] and cis-[Pt(NH3)2Cl2(OH)2] is carried out, and immobilization of platinum complexes on the nanoporous carbon substrate is investigated. The solubility of cis-[Pt(NH3)2Cl2] in 1 M HCl solution is determined, and the average enthalpy of dissolution is calculated: ΔsolH° = 27.3 ± 0.9 kJ/mol. The batch capacity is determined experimentally for cis-[Pt(NH3)2Cl2] and cis- [Pt(NH3)2Cl2(OH)2] to be 32.9 mg/g (0.17 mg-equiv/g) and 47.6 mg/g (0.24 mg-equiv/g), respectively. Immobilization of platinum complexes on the oxidized carbon surface is found to take place due to interaction between carboxy groups and ammine groups of platinum complexes. The resulting heat capacity curves are used to calculate the enthalpies of adsorption for cis-[Pt(NH3)2Cl2] and cis-[Pt(NH3)2Cl2(OH)2] on the oxidized carbon surface, equal to 24.46 and 27.46 kJ/mol, respectively.
