METHOD OF MODIFYING CARBON SURFACE Russian patent published in 2013 - IPC C06B21/00 C10L9/10 

FIELD: chemistry.

SUBSTANCE: method involves preparing a carbon suspension in aqueous copper acetate solution in weight ratio C : H₂O : Cu(CHCOO)₂-H₂O = 1 : 10…15 : 0.25…0.30, heating to 90...100°C, adding aqueous sodium hydroxide solution to the carbon suspension with weight ratio of copper acetate to sodium hydroxide Cu(CH₃COO)₂·H₂O : NaOH = 1 : 1.05…1.2 for 20…30 minutes, adding aqueous solution of a surfactant - octyl phenyl ether of polyethylene oxide to carbon of 0.005…0.02 : 1. The mixture is then held while stirring for 10…15 minutes and then cooled to 25…30°C, followed by filtration, washing with water and drying at temperature of 90…100°C to constant weight.

EFFECT: invention enables to modify the surface of carbon with copper oxide with maximum output.
