Conclusions

  1. 1.

    The state of the Cu2+ cations in the zeolite framework has a decisive influence on the nature of their interaction with CO.

  2. 2.

    Isolated Cu2+ cations in zeolites do not interact with CO in the interval from −196 to 500°.

  3. 3.

    Weak magnetic associates of Cu2+ cations in zeolites in the interval from −100 to −196° form adsorption complexes with CO, and at 300 to 500° they oxidize CO to CO2 and are reduced to Cu+ cations. The latter processes evidently occur with the participation of nonskeletal oxygen of the hydroxyls in the coordination sphere of the Cu2+ cations, entering into the composition of the weak magnetic associates.

  4. 4.

    Strong associates of Cu2+ cations, including a nonskeletal bridge oxygen, oxidize CO to CO2 and carbonates even at low temperatures. The catalytic activity of CuY zeolites in the oxidation of CO is caused by the presence of strong magnetic associates of Cu2+ cations in them.
