Abstract

The invention discloses a preparation method of a graphite phase carbon nitride nanotube. The method comprises the steps that (1) melamine powder is added into a crucible and put in a muffle furnace for heating and calcining for 2 hours, wherein the heating rate is 10 DEG C / min; (2) the product obtained in step (1) is ground into powder and then placed into ethanol for ultrasonic cutting, whereinthe ethanol is presented in an amount of 50 mL; (3) the product obtained in step (2) is filtered and dried, and then transferred into the muffle furnace for calcining, wherein the heating rate is 10 DEG C / min; (4) the product obtained in step (3) is rapidly transferred into ice water for stirring, filtration is carried out, then calcination is carried out for 12 hours at 80 DEG C, and the carbon nitride nanotube is obtained. The preparation method of the graphite phase carbon nitride nanotube has the advantages that the cost is low, the preparation method is simple and easy to conduct, and thecarbon nitride nanotube prepared through the method is regular in appearance and has no damage.

Description

technical field [0001] The invention relates to the field of inorganic photocatalytic nanomaterials, in particular to a method for preparing graphite-phase carbon nitride nanotubes. Background technique [0002] With the increasing energy crisis and environmental pollution, there is an urgent need to develop renewable energy technologies. Artificial photocatalysis is considered to be an efficient method without pollution. Today, hundreds of semiconductor materials are available. However, its practical application is greatly hindered considering the high cost, high bandgap width, and low charge separation rate [1] . Recently, researchers developed a novel visible light-driven photocatalyst graphitic carbon nitride with excellent photochemical stability and suitable energy band position [2] . However, its efficiency is still affected by the low specific surface area and high charge recombination rate. [0003] This problem can be solved by preparing carbon nitride materi...
