SEM, FTIR and TGA analysis of Graphitic carbon nitride (g-C3N4) and its modification as a composite material

This paper describes the preparation of g-C3N4 by polycondensation of melamine at 511 °C and its subsequent doping with Fe2O3, Cu, GO, rGO, DA and their combinations. Graphitic carbon nitride represents an innovative material with numerous applications, particularly within the domains of catalysis and water treatment. FTIR and thermogravimetric analysis were predominantly employed for the purpose of identification, while SEM images were captured at incremental resolutions. The subsequent section of the manuscript delineates the fabrication of composite materials within polymers, including PE-foil and PP-filaments intended for 3D printing, as well as PVB into nanofibers via electrostatic spinning techniques. The objective of this study was to examine the thermal stability of nanofibers produced from PVB in conjunction with g-C3N4 composite (18-20 %) utilizing two methodologies: EL DC spinning and EL AC spinning. The material exhibiting the most efficacious synthesis will undergo further assessment to evaluate its potential utility in the photocatalytic degradation of environmental pollutants.
