Abstract
Disclosed are a honeycomb-like homo-type heterojunction carbon nitride composite material and a preparation method thereof, and an application of the honeycomb-like homo-type heterojunction carbon nitride composite material in catalytic treatment of waste gas. The preparation method includes the following steps: with two different carbon nitride precursors namely urea and thiourea as raw materials, weighing certain amounts of the urea and the thiourea, adding the urea and the thiourea into a crucible, adding a certain amount of ultrapure water, placing the crucible in a muffle furnace, and carrying out calcination molding. The honeycomb-like homo-type heterojunction carbon nitride prepared by the one-step method has good photocatalytic effect to catalytic degradation of NO; meanwhile, the honeycomb-like homo-type heterojunction carbon nitride composite material has the advantages of rich and easily-available production raw materials, good stability, reusability, etc., and has application prospects in the field of treatment of NO in the air.
