Development of g-C3N4/ZnO nanocomposite as a novel, highly effective and durable photocatalytic antibacterial coating for cotton fabric

Review and Perspective on Rational Design and Interface Engineering of g-C3N4/ZnO: From Type-II to Step-Scheme Heterojunctions for Photocatalytic Applications

“…The combination of these two factors defines the synergistic effects in this heterostructure, and investigations on simultaneous pollutant degradation and HER might provide much deeper insights into the synergism. Few reports on the synthesis of quantum dot-based GCN/ZnO, 320 GCN/mixed metal oxides 321 would be more exciting for photocatalysis owing to the unique electronic band structures, while design of these composites on a floating substrate 162 and cotton fabric 163 are beneficial due to their ability to be used multiple times without the loss of catalyst particles. The design of GCN/ZnO through modification with cocatalytic materials to harvest the solar spectrum complemented with an improved surface area is very important for energy−environment applications.…”

“…The major advantage of the wet impregnation method is that the composite can be deposited over different substrates such as plastic, cotton fabric, and polysulfone, which not only avoids the loss of the composite during the recycling tests but also saves the cost included in the fabrication steps. − The physisorption might lead to poor interfacial interactions, and thus composite stability remains ambiguous. The uniform thickness of GCN sheets over the ZnO surface and intimate contact between them is difficult to achieve through the calcination method, as it may sometimes lead to agglomeration of ZnO-NPs .…”

“…[109] Seyed et al developed g-C 3 N 4 /ZnO photocatalytic antibacterial membranes, bacterial re-duction percentages against S. aureus and E. coli were 81.6% and 78.8%, respectively, under visible light irradiation after 3 h, indicating that g-C 3 N 4 -coated cotton fibers could inhibit bacterial growth (Figure 11d). [118] This is because g-C 3 N 4 nanosheets provide a sufficient porous surface for ZnO NPs that not only immobilizes the ZnO NPs on the surface of the fabrics but also forms heterojunction compounds that allow extraordinary photocatalytic properties to eliminate hazardous bacteria.…”
