Heterogeneous photocatalysts are widely used for wastewater and natural water treatment from organic pollutants. In this paper, g-C3N4-based photocatalysts were synthesized by thermal condensation of melamine. The effect of melamine pretreatment with acetic acid on the physicochemical properties of g-C3N4 was studied using differential thermogravimetric analysis (DTA-TG), X-ray diffraction (XRD), FT-IR spectroscopy, scanning electron microscopy (SEM), and low-temperature nitrogen adsorption-desorption. The catalytic activity of synthesized photocatalysts was evaluated during the oxidative degradation of Rhodamine B in an aqueous solution under “soft” (type A) and “hard” (type B) UV irradiation.
