“…The g -C 3 N 4 exhibits good photoelectric properties and band structure. In our case, however, since this study was performed under room conditions in vitro, the results showed that fungal growth was not inhibited [ 21 , 29 , 30 ]. Thus, future studies should be conducted in such a way that a fungal species should be subjected to photocatalytic irradiation [ 1 ].…”

The active and inexpensive catalyst cupric oxide (CuO) loaded foliar fertilizer of graphitic carbon nitride (g-C3N4) is investigated for biological applications due to its low cost and easy synthesis. The synthesized CuO NPs, bulk g-C3N4, exfoliated g-C3N4, and different weight percentages of 30 wt%, 40 wt%, 50 wt%, 60 wt%, and 70 wt% CuO-loaded g-C3N4 are characterized using different analytical techniques, including powder X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, and ultraviolet-visible spectroscopy. The nanocomposite of CuO NPs loaded g-C3N4 exhibits antibacterial activity against Gram-positive bacteria (Staphylococcus aureus and Streptococcus pyogenes) and Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa). The 20 μg/mL of 70 wt% CuO/g-C3N4 nanocomposite showed an efficiency of 98% for Gram-positive bacteria, 80% for E. Coli, and 85% for P. aeruginosa. In the same way, since the 70 wt% CuO/g-C3N4 nanocomposite showed the best results for antibacterial activity, the same compound was evaluated for anti-fungal activity. For this purpose, the fungi Fusarium oxysporum and Trichoderma viride were used. The anti-fungal activity experiments were not conducted in the presence of sunlight, and no appreciable fungal inhibition was observed. As per the literature, the presence of the catalyst g-C3N4, without an external light source, reduces the fungal inhibition performance. Hence, in the future, some modifications in the experimental conditions should be considered to improve the anti-fungal activity.
