“…The other peak situated at 13.1 • were indexed as (100) in the JCPDS 87-1526. In addition, the distinct diffraction peaks at 2 = 31.2 • , 38.0 • , 44.2 • , 64.4 • and 77.4 • could be seen obviously in Ag/g-C 3 N 4, which are agreement with the diffraction peaks of Ag species and indicates the formation of Ag/g-C 3 N 4 dualistic composites [35,36]. All the characteristic diffraction peaks of g-C 3 N 4 could be found in Ag/g-C 3 N 4 .…”

“…The XRD pattern of the ternary composite 1%Ag/S5 is similar with that of S5 due to the low content of Ag. When the content of Ag increases from 4% to 10%, the diffraction peaks appear at 38.1° and 44.2°, corresponding to the (111) and (200) planes of Ag crystal, respectively [32]. Their intensities become stronger with the increasing content of Ag.…”

“…The other promising way is to introduce noble metal nanoparticles (Pt, Au, and Ag) into g-C 3 N 4 . Ag nanoparticles are often used to combine with other semiconductors, such as g-C 3 N 4 /Ag/MoS 2 [31], Ag/ Fe 3 O 4 /g-C 3 N 4 [32], g-C 3 N 4 /Ag 2 WO 4 /Ag [33], Ag@AgBr/ g-C 3 N 4 [34], and g-C 3 N 4 /Ag/TiO 2 [35]. The important reasons are that Ag nanoparticles have unique electrical, optical, and magnetic features [36], and a relatively cheap price compared with platinum or gold.…”

Abstract:The CeVO 4 /graphitic C 3 N 4 composites have exhibited much enhanced photocatalytic property for degrading methylene blue (MB) pollutant under visible light irradiation compared with single-phase g-C 3 N 4 or CeVO 4 . The composite S5 obtained from an optimized mass ratio (5%) of CeVO 4 to dicyanamide (DCDA) exhibits the highest photocatalytic activity. Here, ternary Ag/CeVO 4 /g-C 3 N 4 composites denoted as X%Ag/S5 were prepared by an ultrasonic precipitation method to improve the photocatalytic property of S5. The TEM images show that CeVO 4 and Ag nanoparticles are well distributed on the layered g-C 3 N 4 , which agree well with the XRD results. The UV spectra show that the 7%Ag/S5 sample has the widest absorption range and the enhanced absorption intensity under visible light irradiation. The corresponding band gap of 7%Ag/S5 (2.5 eV) is much lower than that of S5 (2.65 eV). The corresponding k value of 7%Ag/S5 is much higher than those of g-C 3 N 4 and CeVO 4 . The degradation experiments for MB solution suggest that the 7%Ag/S5 sample has the optimal photocatalytic performance, which can degrade MB solution completely within 120 min. The enhanced photocatalytic property of the composites is ascribed to not only the effect of heterojunction structure, but also the surface plasma resonance effect of Ag nanoparticles.

“…The degradation rate of bisphenol A over g‐C 3 N 4 /HRP reaches to 97.9% within 60 min, which is dramatically higher than those over single HRP (7.4%) and g‐C 3 N 4 (25.9%). For the quantitative comparison, the rate constants are obtained by the plots of ln( C 0 / C ) versus time according to pseudo first–order kinetic equation (Figure S3, Supporting Information) . The degradation rate constant of bisphenol A (0.069 min −1 ) also reaches up to 34.5 and 13.8 times than those of single HRP (0.002 min −1 ) and g‐C 3 N 4 (0.005 min −1 ), respectively.…”

It has always been a challenge to fabricate artificial catalytic system as one promising strategy of using solar energy for chemical synthesis, fuel production, electrochemical detection, pollutant degradation, etc. Here a new g‐C3N4/horseradish peroxidase hybrid nano–bio artificial catalytic system is exploited. The coupling effect between photocatalysis and biocatalysis cycles not only forcefully improves the separation efficiency of charge carriers but also continuously produces more OH active species, finally realizing high‐efficiency and unselective degradation of various persistent phenolic pollutants, such as bisphenol A, phenol, p‐nitrophenol, and 2‐naphthol. This work provides an innovative design idea to fabricate general artificial catalytic system that may be widely used in treatment of organic pollutants.
