METHOD OF MODIFYING SURFACE OF INORGANIC OXIDE

摘要

FIELD: chemistry.SUBSTANCE: invention relates to a method of modifying the surface of an inorganic oxide. The method involves treating an inorganic oxide with a water-soluble nickel (II) salt to form nickel (II) oxide nanoparticles on the surface of the inorganic oxide. The inorganic oxide and an alkali are successively added to the aqueous nickel (II) salt solution preheated to 50-90°C. When the obtained mixture cools down, a solution of sodium tetrahydroborate in an aliphatic alcohol is then added. An "aliphatic alcohol - water" azeotropic mixture is then distilled from the obtained product. The product is held at 70-90°C and then successively washed in water and twice in aliphatic alcohol. The separated precipitate is held in air until nickel is completely oxidised to nickel (II). The inorganic oxide used is aluminium oxide or silicon oxide.EFFECT: low power consumption of the process.3 ex
