Fabrication of heterostructured Ag/AgCl@g-C3N4@UIO-66(NH2) nanocomposite for efficient photocatalytic inactivation of Microcystis aeruginosa under visible light

In Situ Coupling Carbon Defective C3N5 Nanosheet with Ag2CO3 for Effective Degradation of Methylene Blue and Tetracycline Hydrochloride

“…As shown in Figure 7 c, the CNAC-10 composite has a smaller Nyquist arc radius than g-C 3 N 5 , n-C 3 N 5 , Ag 2 CO 3 , and other CNAC-X composites. The charge transfer resistance of the catalyst is positively correlated with the arc radius on the electrochemical impedance spectrum [ 60 , 61 ]. Therefore, EIS analysis indicates that the CNAC-10 composite has lower resistance to photogenerated charge migration than other samples.…”

Insights into the photocatalytic ozonation over Ag2O-ZnO@g-C3N4 composite: Cooperative structure, degradation performance, and synergistic mechanisms

“…After the incorporation of Ag2O-ZnO, that of Ag2O-ZnO@CNx catalysts were reduced, which might be caused by the regular dispersion of Ag2O-ZnO particles occupying a proportion of the spaces of the g-C3N4 or anchored in the g-C3N4 pores [34,35]. In addition, with the quality of g-C3N4 increased to 0.8 g, the specific surface area, pore volume and pore diameter of Ag2O-ZnO@CN0.8 further decreased to 33.1048 m² g −1 , 0.0538 cm³ g −1 , and 64.9897 Å, which was mainly due to the reason that the layers of g-C3N4 nanosheet would block some pores of Ag2O-ZnO@CNx composite [24]. Amongst, the Ag2O-ZnO@CN0.4 had the largest pore diameter (73.5324 Å) and displayed a better pore size distribution (5-30nm) than g-C3N4 (10-30nm), that would be useful to improve the catalytic activity of catalyst [36].…”

“…It was reported that the higher intensity of the PL emission is also related to the higher recombination rate of photo-generated e − −h + pairs [24]. Applying the excitation wavelength at 325 nm has caused the appearance of the main signal of Ag2O-ZnO@CNx at around 440 nm, which can be attributed to the emission through exciton-exciton photo-carrier collision systems [24]. Moreover, it was obvious that all the Ag2O-ZnO@CNx composites had similar PL spectra and the peak intensity was higher with more amount of g-C3N4 loaded.…”

Effect of the Transforming Ag into an Active Species (Silver Chloride) for the Acetylene Hydrochlorination

“…Therefore, we investigated the role of Ag in other domains and elucidated its good catalytic activity. In light of Lin [14] and Fan [15] et al, Ag species can utilize high visible light energy, as well as effectively transfer charge carriers. Their findings are justified by the special electronic structures of full or empty Ag 3d orbit, which enables it to easily form metal-heterojunction structures by fusing with other semiconductors.…”
