“…And the broad absorption bands at 2900–3500 cm −1 originated from the NH stretching vibration in the triazine ring and the OH stretching vibration of the hydroxyl group in OCN and the CH stretching vibration in the imidazole ring. The peak intensity of the PBF‐OCN was greater at this point compared with that of OCN, the change of peak intensity and the peak position might be due to the introduction of more imidazole ring 59,60 …”

“…The peak intensity of the PBF-OCN was greater at this point compared with that of OCN, the change of peak intensity and the peak position might be due to the introduction of more imidazole ring. 59,60 The chemical compositions and valence states of OCN and PBF-OCN-3 were analyzed by XPS. As shown in Figure 3c and Table 1, 61 The shift of the four peaks and the differences in the peak areas compared to the C 1 s spectra (Figure 3g) of OCN could be ascribed to the introduction of the imidazole ring and the carbon chain in PBF.…”

With the increase of drug‐resistant bacteria and the limitations of traditional antibacterial methods, photocatalytic inhibition has received widespread attention as a novel antibacterial method. In this paper, poly(1‐vinyl‐3‐ethylimidazolium tetrafluoroborate) composite oxygenated carbon nitride (PBF‐OCN) were prepared by in situ free radical polymerization using 1‐vinyl‐3‐ethylimidazolium tetrafluoroborate and OCN. The results showed that the light absorption ability and electron hole separation rate of PBF‐OCN were greatly improved compared with that of OCN, and the rate constant for photocatalytic removal MB of PBF‐OCN‐1 was about 1.39 times of that OCN. The growth of Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) could be significantly inhibited by PBF‐OCN under visible light, among which, the inhibition of PBF‐OCN‐3 was the most excellent, with the diameter of the circle of inhibition reaching 20.69 mm for E. coli, and 21.30 mm for S. aureus, and the inhibition rate against E. coli calculated by plate counting method reached 97.0%. The minimum inhibitory concentration for E. coli and S. aureus was 0.0625 mg/mL, respectively, and the possible inhibition mechanism of the samples was explored. The good synergistic antibacterial effect of PBF‐OCN is expected to be applied in water treatment, antibacterial devices, packaging materials, and other fields.

“…[89] The electrochemical properties of the a-C thin film have been proved to be modulated by thickness control, doping, and the sp 2 /sp 3 ratio. [91][92][93][94][95] The a-C thin film acts as electrochemical and physical barriers due to the chemical inertness. [91,96] Tetrahedral amorphous carbon (ta-C) thin film showed superior corrosion resistance rather than hydrogenated diamond-like carbon (DLC:H) thin film (Figure 6a).…”

While various crystalline carbon allotropes, including graphene, have been actively investigated, amorphous carbon (a‐C) thin films have received relatively little attention. The a‐C is a disordered form of carbon bonding with a broad range of the CC bond length and bond angle. Although accurate structural analysis and theoretical approaches are still insufficient, reproducible structure–property relationships have been accumulated. As the a‐C thin film is now adapted as a hardmask in the semiconductor industry and new properties are reported continuously, expectations are growing that it can be practically used as active materials beyond as a simple sacrificial layer. In this perspective review article, after a brief introduction to the synthesis and properties of the a‐C thin films, their potential practical applications are proposed, including hardmasks, extreme ultraviolet (EUV) pellicles, diffusion barriers, deformable electrodes and interconnects, sensors, active layers, electrodes for energy, micro‐supercapacitors, batteries, nanogenerators, electromagnetic interference (EMI) shielding, and nanomembranes. The article ends with a discussion on the technological challenges in a‐C thin films.

“…Some previous studies have shown that g-C3N4 can work as photoelectrodes for PEC applications. [17][18][19][20][21][22][23][24][25][26] However, the previous pure g-C3N4 electrode presents limited PEC efficiencies due to its intrinsic drawbacks, such as poor conductivity, limited visible-light absorption up to 450 nm, and weak interfaces between the pasted bulk g-C3N4 layer and the conducting substrate.…”
