Graphitic carbon nitride was synthesized starting from melamine and uric acid. Uric acid was chosen because it thermally decomposes and condenses with melamine at temperatures between 400-600 °C. The reagents were mixed with alumina and then treated in a furnace under a nitrogen flow. Alumina facilitates the deposition of the graphitic carbon nitride layers on the exposed surfaces. This method can be compared to in situ chemical vapor deposition (CVD). The infrared (IR) spectra and X-ray diffraction (XRD) patterns are consistent with the formation of graphitic carbon nitride based on a heptazine block structure. Transmission electron microscopy (TEM) analysis showed that these carbon nitrides exhibit poor crystallinity and nanoscale texture. The thermal decomposition of graphitic carbon nitride occurs via cyano formation, involving bridging tertiary nitrogen and bonded carbon belonging to the heptazine ring, which leads to ring opening and subsequent network breakdown. This inference was made by correlating IR and X-ray photoelectron spectroscopy (XPS) results. This appears to be a simple and promising route for synthesizing graphitic carbon nitride. Our final material is a composite made of alumina cores covered with carbon nitride layers.

In this study, a novel bio-based acidic nano-organocatalyst was designed, synthesized, and fully characterized through the condensation reaction of uric acid and phosphorous acid. The resulting compound, named Theanine Tetraphosphonic Acid (TTPA), was prepared under reflux in ethanol.
Experimental Procedure
In a 50 mL round-bottom flask, a mixture containing uric acid (1 mmol, 0.17 g), paraformaldehyde (4 mmol, 0.12 g), phosphorous acid (4 mmol, 0.32 g), p-TSA (10 mol%, 0.017 g), and 25 mL of ethanol was refluxed for 18 hours. Following this period, the resulting white precipitate was filtered off and dried under vacuum to yield Theanine Tetraphosphonic Acid (TTPA).
