METHOD EMPLOYING QUATERNARY AMMONIUM BASE TO PREPARE C-N CO-DOPED NANOTUBE/NANOROD CATALYTIC MATERIAL

摘要

A method employing a quaternary ammonium base to prepare a C-N co-doped nanotube/nanorod catalytic material. The method comprises: dispersing P25 in an aqueous solution having a high concentration of alkali; fully stirring the aqueous solution with a magnetic stirrer; then placing the aqueous solution into a reaction kettle internally provided with a polytetrafluoroethylene liner; after heating at a constant temperature, filtering and washing the same; mixing an acquired product with an aqueous solution of inorganic acid; fully stirring to cause the product and the aqueous solution to react; performing filtering, washing and drying, so as to acquire a H₂Ti₃O₇ nanotube material having a layered pipe wall structure; the acquired H₂Ti₃O₇ nanotube material and R₄NOH reacting at a room temperature; and performing leaching, drying, and roasting in a nitrogen atmosphere, thereby obtaining a C-N co-doped nanotube catalytic material. A C-N co-doped nanotube catalytic material is used as a catalyst, and a dye solution undergoes photocatalytic degradation under certain conditions to acquire a result indicating that an acquired catalyst has effective catalysis on a dye, can serve as a raw material for catalytic degradation of other contaminants, and is applicable to the treatment of dye wastewater and contaminants.
