Extraordinary photodegradation performance of graphitic carbon nitride derived from tin foil–wrapped urea

Effect of Synthesis Temperature on Transient Photoconductivity of g-C3N4 from Urea

“…The differences in structure arise in synthesizing g-C 3 N 4 , and the conditions utilized can lead to a wide variety of properties in g-C 3 N 4 . ,,,− Some of the different parameters that are commonly varied include synthetic precursor (urea, thiourea, melamine dicyandiamide, etc. ), synthesis temperature (500–650 °C), and temperature ramp rate. ,,− With regards to precursors, there are many nitrogen-rich hydrocarbons, some listed above, but commonly samples synthesized from urea tend to yield the best photocatalysts. − , The ideal synthesis temperature depends on the precursor used, but for g-C 3 N 4 samples derived from urea, the best photocatalysts are annealed at 600 °C. , Ultimately, by varying these parameters, the amount of polymerization varies leading to different polymorphs in the material. , These different polymorphs are what lead to different properties within the material which then affect the photocatalytic rate of the material …”
