2D III‐nitride materials have been receiving considerable attention recently due to their excellent physicochemical properties, such as high stability, wide and tunable bandgap, and magnetism. Therefore, 2D III‐nitride materials can be applied in various fields, such as electronic and photoelectric devices, spin‐based devices, and gas detectors. Although the developments of 2D h‐BN materials have been successful, the fabrication of other 2D III‐nitride materials, such as 2D h‐AlN, h‐GaN, and h‐InN, are still far from satisfactory, which limits the practical applications of these materials. In this review, recent advances in the properties, growth methods, and potential applications of 2D III‐nitride materials are summarized. The properties of the 2D III‐nitride materials are mainly obtained by first‐principles calculations because of the difficulties in the growth and characterizations of these materials. The discussion on the growth of 2D III‐nitride materials is focused on 2D h‐BN and h‐AlN, as the developments of 2D h‐GaN and h‐InN are yet to be realized. Therefore, applications have been realized mostly based on the 2D h‐BN materials; however, many potential applications are cited for the entire range of 2D III‐nitride materials. Finally, future research directions and prospects in this field are also discussed.

“…In recent decades, various methods including ion-exchange [ 7 ], membrane separation [ 8 ], chemical oxidation [ 9 ], photodegradation [ 10 , 11 ], adsorption [ 12 , 13 , 14 , 15 ] and other technologies [ 16 , 17 , 18 ] have been employed to treat TC pollution in water. Among above methods, the adsorption is widely used in the field of TC wastewater treatment due to its advantages such as simple operation, low price, random reaction conditions, no significant changes in active sites and spatial structure after adsorption, and reusability of absorbents [ 19 , 20 , 21 ].…”

Designing Phenyl Porous Organic Polymers with High-Efficiency Tetracycline Adsorption Capacity and Wide pH Adaptability

Adsorption is an effective method to remove tetracycline (TC) from water, and developing efficient and environment-friendly adsorbents is an interesting topic. Herein, a series of novel phenyl porous organic polymers (P-POPs), synthesized by one-pot polymerization of different ratios of biphenyl and triphenylbenzene under AlCl3 catalysis in CH2Cl2, was studied as a highly efficient adsorbent to removal of TC in water. Notably, the obtained POPs possessed abundant phenyl-containing functional groups, large specific surface area (1098 m2/g) with abundant microporous structure, high pore volume (0.579 cm3/g), favoring the removal of TC molecules. The maximum adsorption capacity (fitted by the Sips model) could achieve 581 mg/g, and the adsorption equilibrium is completed quickly within 1 h while obtaining excellent removal efficiency (98%). The TC adsorption process obeyed pseudo-second-order kinetics and fitted the Sips adsorption model well. Moreover, the adsorption of POPs to TC exhibited a wide range of pH (2–10) adaptability and outstanding reusability, which could be reused at least 5 times without significant changes in structure and efficiency. These results lay a theoretical foundation for the application of porous organic polymer adsorbents in antibiotic wastewater treatment.

“…Volatile organic compounds (VOC) or poisonous gases (PG) such as 2-butanone, ethanol, acetone, nitrogen (II) oxide, nitrogen (IV) oxide, and ammonia are incredibly harmful to human health and the environment. Human health is threatened by the combustion of organic fuels and leakages of toxic gases [ 46 , 47 , 48 ]. Methyl ethyl ketone (2-butanone) is a colorless liquid with a sharp, sweet odor, commonly used as a solvent in manufacturing processes to produce plastics, textiles, and paraffin wax, and in electronics.…”

Graphitic carbon nitride (g-C3N4) is a two-dimensional conjugated polymer that has attracted the interest of researchers and industrial communities owing to its outstanding analytical merits such as low-cost synthesis, high stability, unique electronic properties, catalytic ability, high quantum yield, nontoxicity, metal-free, low bandgap energy, and electron-rich properties. Notably, graphitic carbon nitride (g-C3N4) is the most stable allotrope of carbon nitrides. It has been explored in various analytical fields due to its excellent biocompatibility properties, including ease of surface functionalization and hydrogen-bonding. Graphitic carbon nitride (g-C3N4) acts as a nanomediator and serves as an immobilization layer to detect various biomolecules. Numerous reports have been presented in the literature on applying graphitic carbon nitride (g-C3N4) for the construction of electrochemical sensors and biosensors. Different electrochemical techniques such as cyclic voltammetry, electrochemiluminescence, electrochemical impedance spectroscopy, square wave anodic stripping voltammetry, and amperometry techniques have been extensively used for the detection of biologic molecules and heavy metals, with high sensitivity and good selectivity. For this reason, the leading drive of this review is to stress the importance of employing graphitic carbon nitride (g-C3N4) for the fabrication of electrochemical sensors and biosensors.
