METHOD FOR RAPIDLY PREPARING MICA-SUPPORTED CARBON NITRIDE PHOTOCATALYTIC MATERIAL BY MEANS OF MICROWAVES

摘要

Disclosed is a method for rapidly preparing a mica-supported carbon nitride photocatalytic material by means of microwaves, wherein the mica-supported carbon nitride photocatalytic material is prepared by coating the surface of a two-dimensional flaky mica as a support with a layer of microwave-absorbing material, i.e., stannic oxide, and subjecting same to a microwave method with an amino compound as a material for the synthesis of a graphite-like carbon nitride. Stannic oxide has a very good microwave-absorbing property. By mixing same with the amino compound and by means of the microwave effect heating from outside in, the depth of the microwave action is expanded, the efficiency and uniformity of the microwave synthesis of the mica-supported carbon nitride are improved, the preparation time is reduced, the usage amount of the external microwave medium is greatly reduced, and resources are saved.
