The invention discloses a carbon-doped
graphite-phase
carbon nitride nanotube and a preparation method thereof. A preparation process of the carbon-doped
graphite-phase
carbon nitride nanotube comprises the steps of firstly, dispersing
melamine into an
ethanol solution of aminopropyl trimethoxysilane, carrying out a
hydrothermal reaction, and then carrying out centrifugal
drying to obtain
solid powder; mixing (3-mercaptopropyl) trimethoxysilane with tetraethoxysilane and evenly stirring, adding a
mixed solution of
ethanol and water into the mixture and stirring again, and carrying out
centrifugal separation to obtain a modified
polystyrene (MPS)-modified SiO2 solution; adding the
solid powder of the pretreated
melamine into the MPS-modified SiO2 solution, stirring, then centrifuging,
drying, and calcining to obtain a product;
etching the product by using a
hydrogen fluoride (HF) solution to obtain the carbon-doped
graphite-phase
carbon nitride nanotube. The preparation process of the carbon-doped graphite-phase carbon
nitride nanotube is novel, convenient and fast, and high in
controllability; the obtained nanotube has the advantages of being more uniform in size, thinner in tube wall, better in
conductivity, excellent in photocatalytic property, and the like; the carbon-doped graphite-phase carbon
nitride nanotube can be used for constructing multiple heterostructures, and has good application potential in the aspects of
photocatalytic degradation of organic pollutants, water photolysis for
hydrogen production, and the like.
