Abstract

The invention discloses a method for preparing porous graphite-phase carbon nitride nanosheet powder, which uses carbon-nitrogen precursors, carbonated beverages and water as raw materials, and uses carbonated beverages to assist hydrothermal treatment of conventional carbon-nitrogen precursors to prepare modified precursors; Then the above-mentioned modified precursor is calcined at high temperature to obtain porous g-C 3 N 4 Nanosheet powder. The present invention uses common carbonated beverages to assist hydrothermal modification of carbon-nitrogen precursors, and obtains porous g-C with nanosheet structure 3 N 4 Powder has the advantages of simple process, wide sources of raw materials, low cost, strong experimental operability, and no special requirements for equipment, and is suitable for large-scale industrial production. The resulting porous g‑C 3 N 4 The nanosheet powder has a significantly porous two-dimensional structure with a complete monolayer and uniform pore distribution, while improving the traditional bulk g-C 3 N 4 Non-porous, easy to agglomerate structural disadvantages; and exhibit good photocatalytic performance.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic material preparation, and in particular relates to a preparation method of porous graphite phase carbon nitride nanosheet powder. Background technique [0002] Graphite carbon nitride (g-C 3 N 4 ), as a two-dimensional semiconductor material with a graphene-like structure, has shown great application potential in the fields of photolysis of water to produce hydrogen, photodegradation of organic pollutants and photoreduction of carbon dioxide. Regular bulk g-C 3 N 4 Although it has certain photocatalytic properties, its application in the field of photocatalysis is severely restricted due to its defects in energy band structure, small specific surface area, easy agglomeration, and irregular morphology. [0003] Existing literature has shown that both "doping" and "morphology control" can effectively improve the physical and chemical properties of a single material, thereby obtaining effi...
