Silica supported visible light active graphitic carbon nitride (g-C3N4) photocatalyst for estrogenic hormones removal and antibacterial activity
Original language description
In this study, we report on a silica-supported graphitic carbon nitride photocatalyst synthesized via a facile heat treatment route of urea and characterized by XRD, SEM, FTIR, and UV-vis spectroscopy. The photocatalytic activity of the as-prepared sample was evaluated by the photodegradation rate of four major estrogenic hormones (El, E2, EE2, E3) under visible light LED irradiation The degradation results showed that the as-prepared sample possessed considerable adsorption affinity for all the tested hormones as well as robust photocatalytic efficiency. Owing to the synergistic adsorptive and photocatalytic activity, elimination rates of 82, 93, 83, and 96% were achieved for the E3, E2, EE2, and El hormones, respectively. In addition, antibacterial tests showed that the as-prepared sample possessed reasonable antibacterial activity against the grampositive (Staphylococcus aureus) and gram-negative (Escherichia coli) bacteria.
