Abstract
A sol-gel method for the synthesis of manganese dioxide nanoparticles stabilized with methionine is proposed. The optical properties of MnO2 sols, its morphology, elemental and phase composition were studied. A quantum-chemical calculation was performed and models for the formation of a chemical bond between a methionine molecule and a fragment of the manganese dioxide unit cell were constructed. According to the results of the computer simulation, the most probable mechanism of stabilization of MnO2 nanoparticles was revealed.
