چکیده
Among various advanced oxidation processes, coupled photocatalysis and heterogeneous Fenton-like catalysis (known as photo-Fenton-like catalysis) to generate highly reactive species for environmental remediation has attracted wide interests. As an emerging metal-free photocatalyst, graphitic carbon nitride (g-C3N4, CN) been recently recognized a promising candidate catalyze robustly reactions wastewater remediation. This review summarizes recent progress in fabricating types of CN-based catalysts the reaction process. Innovative engineering strategies on CN matrix are outlined, ranging from morphology control, defect engineering, nonmetal atom doping, organic molecule doping modification by metal-containing species. The catalytic activities loaded with auxiliary sub-nanoscale (e.g., quantum dots, organometallic molecules, metal cations, single metals) nanoscale metal-based materials critically evaluated. Hybridization bandgap-matching semiconductors construction type-II Z-scheme heterojunctions also examined. critical factors morphology, dimensionality, light absorption, charge excitation/migration, sites, H2O2 generation activation) that determine performance photocatalysts systematically discussed. After examining structure–activity relationship, research perspectives proposed further development toward more efficient their application practical water treatment.

Carbon nitride materials synthesized by Ion-assisted pulsed laser deposition
Synthesis of carbon nitride has been an important topic in materials science since 1993. Ion-assisted pulsed laser deposition is proven to be a good method to deposit carbon nitride thin films. Both amorphous and crystal -C3N4 layers can be deposited on many substrates. A standard experimental set-up comprises a pulsed KrF excimer laser (wavelength 248 nm, duration ∼30 ns) that is used to ablat...
