Synergistic effects of Ag-doped and morphology regulation of graphitic carbon nitride nanosheets for enhanced photocatalytic performance

Emerging and Promising Multifunctional Nanomaterial for Textile Application Based on Graphitic Carbon Nitride Heterostructure Nanocomposites

“…The Ag/g-C 3 N 4 nanocomposites exhibit not only enhanced visible light photocatalytic performance, but also improved antimicrobial performance due to the excellent antimicrobial activity of Ag against a wide range of Gram-negative and Gram-positive bacteria, viruses, fungi, molds, yeasts, and algae [ 52 ]. Ag/g-C 3 N 4 nanocomposites have already been used for the degradation of environmental pollutants, such as in the decolourization of different dyes [ 30 , 53 , 54 , 55 , 56 , 57 , 58 ] and the degradation of organic solvents [ 53 , 59 , 60 , 61 ] and antibiotics [ 62 , 63 , 64 , 65 ]. They have also been used in hydrogen generation [ 66 ]; in microbial disinfection [ 57 , 67 , 68 ]; and as chemical sensors to detect drugs [ 69 , 70 ], biothiols [ 71 ], plant pigments [ 72 ], and pesticides [ 61 ].…”

In another case, Ag/g-C 3 N 4 was used to obtain composites with multiple colors [ 73 ].…”

Graphitic carbon nitride photocatalysis: the hydroperoxyl radical role revealed by kinetic modelling

“…The modification of pristine GCN is necessary to improve the electronic transfer network in the GCN framework by different doping approaches. [81][82][83][84][85] Reactions between 1 O 2 and PhOH or its degradation byproducts, and other reactions regarding 1 O 2 , such as recombination with other radical species, were initially considered in this work. [86][87][88][89][90][91] However, the mentioned reactions and the presence of 1 O 2 proved uneventful as they did not affect the kinetic model fitting.…”

Cd0.5Zn0.5S Quantum Dot-Modified CdIn2S4 Nano-octahedron as the 0D/3D Hybrid Heterojunction for CO2 Photoreduction

“…These limiting factors include strong photocorrosion, high recombination rate of photogenerated carriers, and low quantum yields. ,− Through previous studies, it is not difficult to find out that the basic principles for boosting the catalytic efficiency of photocatalysts mainly include the following: (1) adjusting the band gap and broadening the range of light response; , (2) increasing the specific surface area to provide more reactive sites; − and (3) prolonging the carrier lifetime and restraining the recombination of e – and h + . Therefore, in order to better utilize the abovementioned advantages of ternary metal sulfides and improve their disadvantages, different strategies have been developed, including morphology regulation, , elemental doping, defect engineering, , and heterojunction construction, − sequentially improving their photocatalytic activity and strengthening their photocorrosion resistance stability. Among these modification strategies, compounding with other semiconductors to form a heterojunction is one of the effective measures, for instance, MgIn 2 S 4 /CdS, WO 2.72 /ZnIn 2 S 4 , CdIn 2 S 4 /g-C 3 N 4 , and so forth.…”
