Multiple ordered porous honeycombed g-C₃N₄ with carbon ring in-plane splicing for outstanding photocatalytic H₂ production

Abstract

Morphology regulation and electronic structure modulation are very important means to improve the photocatalytic H2 evolution of metal-free graphitic carbon nitride (g-C3N4) photocatalyst. Herein, we constructed a multiple ordered porous...

Construction of a 2D layered BiVO4/zinc porphyrin (ZnTCPP) S-scheme heterostructure boosting photocatalytic N2oxidation performance

“…Among various renewable energy methods, solar light induced photocatalytic reactions offer a promising way for environmental remediation and renewable energy production. 2 Until now, numerous catalytic reactions have been carried out in the presence of an appropriate photocatalyst and light irradiation 3 such as organic pollutant degradation, 4 water splitting to produce H 2 and O 2 , 5 CO 2 reduction to hydrocarbon fuels, 6 virus inactivation 7 and selective organic synthesis reactions. 8 Recently, photocatalytic nitrogen fixation has received lots of attention due to its mild reaction conditions, environmental friendliness and utilization of solar energy.…”

Copolymerization synthesis of highly hydrophilic carbon nitride for efficient solar hydrogen production

“…5–7 Nonetheless, the photoactivity of pristine PCN is hampered by the constraints on the marginal visible-light absorption and the rapid recombination of photoinduced charge carriers. 8–10 Therefore, multifarious methods have been adopted to enhance the photocatalytic activity, such as the construction of heterojunctions, 11 loading of cocatalysts, 12,13 engineering nanoarchitecture, 14,15 element doping, 16,17 and surface-engineering. 18,19…”

Anchored Cu single atoms on porous g-C3N4 for superior photocatalytic H2 evolution from water splitting

“…[3][4][5] Among those photocatalysts, g-C 3 N 4 has received a lot of interest due to its visible-light responsiveness, high stability, non-toxicity and low cost, etc. [6][7][8] However, the photocatalytic activity of pristine bulk g-C 3 N 4 (BCN) is quite low owing to the fast charge recombination and low specic surface area (SSA), 9 which greatly hinders its industrial application. To improve the photocatalytic activity, numerous research on the modication of BCN has been carried out, including ion doping, 10 morphology controlling, 11,12 hydrogenated, 13 heterostructure constructing, [14][15][16][17] magnetic-eld-promoted photocatalytic, 18 precious metal loading, 19 etc.…”
