“…Under the same experimental conditions, the T N value of black phosphorus can only reach 115% at a much higher incident intensity of 115 GW • cm −2 . For 532 nm excitation, contrary to earlier reports on OL phenomena [21,22], all of the three g-C 3 N 4 samples exhibit the SA effect under picosecond pulses. When the input fluence at the focal point is fixed at 1.66 J • cm −2 (corresponding to an intensity of 55 GW • cm −2 ), the T N values of g-C 3 N 4 -1, g-C 3 N 4 -2, and g-C 3 N 4 -3 samples are 125%, 163%, and 192%, respectively.…”

For the first time to our knowledge, graphitic carbon nitride (g-C 3 N 4) nanosheets are found to be an excellent saturable absorber material in the visible waveband. g-C 3 N 4 exhibits much stronger saturable absorption in this region than in the near-infrared region, unlike other two-dimensional materials such as graphene and black phosphorus. By the Z-scan method, the nonlinear absorption coefficient β of the material is first measured at three visible wavelengths, and for g-C 3 N 4 it is −2.05, −0.34, and −0.11 cm • GW −1 at 355, 532, and 650 nm, respectively. These are much larger than −0.06 cm • GW −1 at 1064 nm.

“…As mentioned above, the structure of g‐C 3 N 4 is flexible due to its polymeric feature, which favors the formation of heterojunctions with close interconnection between g‐C 3 N 4 and various semiconductors. A large number of semiconductors have been coupled with g‐C 3 N 4 to form semiconductor–semiconductor heterojunctions, including metal oxides (e.g., TiO 2 , ZnO, WO 3 , Cu 2 O, In 2 O 3 , Fe 2 O 3 , MoO 3 , CeO 2 , SnO 2 , and Nb 2 O 5 ), multi‐component oxides (e.g., ZnWO 4 , ZnFe 2 O 4 , Zn 2 GeO 4 , SrTiO 3 , In 2 TiO 5 , DyVO 4 , GdVO 4 , LaVO 4 , YVO 4 , NaTaO 3 , NaNbO 3 , HNb 3 O 8 , H 2 Ta 2 O 6 , and H 3 PW 12 O 40 ), metal oxynitrides (e.g., TaON, and ZnGaNO), metal chalcogenides (e.g., CdS, CuInS 2 , and CuGaSe 2 ,), bismuth‐based compounds (e.g., BiPO 4 , BiVO 4 , Bi 2 WO 6 , BiOCl, BiOBr, BiOI, Bi 2 O 2 CO 3 , and Bi 5 Nb 3 O 15…”

Semiconductor-based photocatalysis is considered to be an attractive way for solving the worldwide energy shortage and environmental pollution issues. Since the pioneering work in 2009 on graphitic carbon nitride (g-C3N4) for visible-light photocatalytic water splitting, g-C3N4 -based photocatalysis has become a very hot research topic. This review summarizes the recent progress regarding the design and preparation of g-C3N4 -based photocatalysts, including the fabrication and nanostructure design of pristine g-C3N4 , bandgap engineering through atomic-level doping and molecular-level modification, and the preparation of g-C3N4 -based semiconductor composites. Also, the photo-catalytic applications of g-C3N4 -based photocatalysts in the fields of water splitting, CO2 reduction, pollutant degradation, organic syntheses, and bacterial disinfection are reviewed, with emphasis on photocatalysis promoted by carbon materials, non-noble-metal cocatalysts, and Z-scheme heterojunctions. Finally, the concluding remarks are presented and some perspectives regarding the future development of g-C3N4 -based photocatalysts are highlighted.

“…Herein, we present a brief overview on the recent progress of g-C 3 N 4 -based photocatalysts. Many methods, such as doping [6][7][8], the introduction of nitrogen deficient [9,10], forming composite with graphene [11][12][13][14], metal [15][16][17], metal oxide [18][19][20][21][22][23] and others [24][25][26][27], can effectively improve the dissociation efficiency of water. The g-C 3 N 4 nanosheets not only can enhance the photoabsorption but can provide high specific surface areas [28][29][30][31].…”
