Investigation on the thermal behavior of g-C₃N₄/MoS₂ nanocomposite produced by microwave-assisted method

The escalating environmental consciousness and the increasing stringency of regulatory frameworks underscore the environmental consequences associated with the utilization of cutting fluids. The study utilized solid nanolubricants composed of g-C₃N₄/MoS₂ nanocomposites. Thermal analysis techniques for the characterization of g-C₃N₄/MoS₂ nanocomposites were used in this work, including thermogravimetric analysis and differential scanning calorimetry. The calcination approach was used to create the graphitic carbon nitride nanosheet, and the microwave-assisted method was used to synthesized the nanocomposite with molybdenum disulfide. Some well-known techniques were used to characterize the samples’ structure and morphology. Molybdenum disulfide and graphitic carbon nitride were found to coexist, according to morphological examination, and the layer-structured MoS₂ was evenly distributed over graphitic carbon nitride nanosheets. Under an inert atmosphere, the samples have been heated to 1150 °C with a constant heating rate of 10 °C/min using nitrogen gas. The thermal assessment of the composite also provides useful information for determining its suitability for high-temperature applications. Activation energy was found to be approximately 20.9 kJ/mol. The inclusion of g-C₃N₄ in nanocomposite verifies the enhancement of the thermal characteristics and the shift in the temperature of the degradation process.
