Silver Nanoparticles Modified Graphitic Carbon Nitride Nanosheets as a Significant Bifunctional Material for Practical Applications

“…On the other hand, the peaks at 288.4 and 289.6 eV may be attributed to CÀO and C=O groups, which reveal the presence of oxygenous groups on the surface of the Ag-NH 2 /GCN. [55] Likewise, the N 1 s core level spectrum observed for the Ag-NH 2 /GCN may also be deconvoluted into three peaks with BE of 398.9, 399.8, and 400.7 eV. Typically, the peak at 398.9 eV should be associated with N atoms sp 2bonded to two carbons (C-N=C), whereas the other two peaks at 399.8 and 401.4 eV are due to tertiary nitrogen (N-(C) 3 ) and amino groups with a hydrogen atom (NÀH), respectively.…”

g‐C3N4‐Based Heterostructured Photocatalysts

“…[20][21][22][23][24][25] Bulk gC 3 N 4 powder can be prepared by the thermal poly condensation of lowcost nitrogencontaining organic pre cursors, e.g., urea, thiourea, melamine, cyanamide, dicyan diamide, guanidine hydrochloride, and so on. [26][27][28][29][30][31][32] The pure bulk gC 3 N 4 prepared by this method suffers from several shortcomings, including low specific surface area, insufficient visible light utilization, and, particularly, rapid recombination Photocatalysis is considered as one of the promising routes to solve the energy and environmental crises by utilizing solar energy. Graphitic carbon nitride (g-C 3 N 4 ) has attracted worldwide attention due to its visible-light activity, facile synthesis from low-cost materials, chemical stability, and unique layered structure.…”

Photocatalytically Active Graphitic Carbon Nitride as an Effective and Safe 2D Material for In Vitro and In Vivo Photodynamic Therapy

“…[8,28] In this study, the synthesis was performed by using a well-established protocol comprising the thermal condensation of guanidine hydrochloride at 550 °C under argon gas flow. [29] The yellowish bulk g-C 3 N 4 powder was exfoliated in water with the help of ultrasonic power to produce g-C 3 N 4 nanosheets ( Figure 1A). Next, its structure was characterized by various methods including scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), diffuse reflectance (DR) UV-vis-NIR, and Brunauer-Emmet-Teller.…”
