Research advances in carbon nitride nanotubes and composites
This paper introduces the structure of g-C3N4 nanotubes,three formation methods of g-C3N4 nanotubes,template method,supramolecular precursor assemblies and nano-/microsheet scrolling.Based on the latest research results obtained by domestic and foreign researchers in g-C3 N4 nanotubes,the research on photocatalytic production of H2,degradation of pollutant,reduction of CO2,formation of H2O2 and sensor from g-C3N4 nanotube composite are presented.At present,the materials compounded with g-C3N4 nanotubes are limited to single atoms or small molecules,in order to enhance the application of g-C3N4 nanotubes,the researchers should try the study of g-C3N4 nanotubes and polymer composite based on the existing nanotube and polymer composite data.The future opportunities and challenges of g-C3N4 nanotube materials are presented.
