FIELD: chemistry.
SUBSTANCE: method of producing platinum (IV) dioxide on the surface of a support includes reacting aqueous platinum nitrate solution with NO, wherein NO is added to the aqueous platinum nitrate solution until the colour of the solution turns from reddish-brown to yellow at (15-80)°C, diluting the obtained solution in water, performing sorption of platinum on the support, drying the obtained material and heating at (250-500)°C.
EFFECT: invention improves the method and stability of the obtained platinum (IV) dioxide on the surface of the support.
