Graphitic carbon nitride (g-C3N4) was synthesized by applying a thermal treatment using waste melamine–formaldehyde product as a precursor. Photocatalytic antibiotic degradation performances of g-C3N4 was investigated. To enhance the photocatalytic activity of g-C3N4, the heat treatment temperature was varied as an experimental variable during the synthesis of g-C3N4, and different proportions of urea and silica template materials were separately mixed with the precursor before the heat treatment. A higher degree of crystallization was obtained as the heat treatment temperature was increased. According to FTIR analysis, it was understood that g-C3N4 was obtained more successfully at the heat treatment temperature of 650 °C. Mixing the precursor with urea and silica template did not significantly affect the chemical structure of the resulting g-C3N4. Mixing waste melamine–formaldehyde product with silica template gave rise to approximately sixfold expansion in the BET surface area of g-C3N4. It was determined that the g-C3N4 particles obtained by mixing waste melamine–formaldehyde product with urea and silica template turned from irregular blocks to spherical structures and the particle size decreased. By mixing waste melamine–formaldehyde product with urea and silica template, the photocatalytic antibiotic degradation efficiency of the resulting g-C3N4 was enhanced. The highest photocatalytic degradation efficiency (41.9%) was obtained on g-C3N4 synthesized from waste melamine–formaldehyde precursor containing urea and silica template under UV light irradiation for 120 min. It was attempted to produce high-value-added photocatalyst from waste melamine–formaldehyde material, reflecting the originality of the present study.
