B-doped C3N monolayer: a robust catalyst for oxidation of carbon monoxide

Two-dimensional carbon nitride (2DCN) nanosheets: Tuning of novel electronic and magnetic properties by hydrogenation, atom substitution and defect engineering

“…A C 3 N nanosheet can show desirable properties for different applications, like nanoelectronics, catalysis, and hydrogen storage. [16][17][18][19][20] C 3 N 4 showed semiconducting properties with the possibility to be a potential photocatalyst for water splitting. 21,22 This structure features intrinsic vacancies that are expected to produce a spinpolarized state, while the electronic property of C 3 N 4 will be drastically modified when atoms are substituted.…”

Introducing novel electronic and magnetic properties in C3N nanosheets by defect engineering and atom substitution

“…14,[20][21][22] In recent years, a large subgroup of 2D crystals has attracted attention consisting of 2D conjugated polymer, which can be stabilized as monolayers by taking advantage of the chemistry of C and N. The strong C bonds give rise to the unique properties of graphene, while the ability of N to take many different positions enhances the option to form a strong covalent organic framework. 23,[23][24][25][26][27][28][29][30][31][32][33] A monolayer of C 3 N was recently successfully synthesized. 34 Due to its uniqe properties 35 several applications have been suggested including solar cell devices, electrolyte gating and doping of transistors, and anode material.…”

“…An important issue is to make the intrinsic band gap of C 3 N tunable, in order to extend its properties. Previously, it was shown that the properties of C 3 N can be tuned by adsorption of adatoms and doping, 5,[41][42][43][44][45][46] adsorptions of molecules, 29,47,48 defect as well as strain engineering 5,46,47,49? ,50 and other methods [51][52][53] The substitution of atoms into carbon nitride materials is of fundamental importance, enabling a wide range of applications by tailoring the electronic and magnetic properties.…”

Effective Air Purification via Pt-Decorated N3-CNT Adsorbent

“…However, the pristine CNTs have some disadvantages of few detection gas types, poor recovery performance, low sensitivity, and poor selectivity (Tabtimsai et al, 2020). Therefore, a variety of methods have been proposed to improve the adsorption performance of CNTs, mainly including functional group modification (Guo et al, 2021;Lim et al, 2021), metal doping (Zhou X. et al, 2010;Cui et al, 2018), non-metal doping (Esrafili and Heydari, 2019;Liu et al, 2019), plasma treatment (Babu et al, 2013;Cui et al, 2020;Sun et al, 2021), molecular sieve treatment, and so on (Niimura et al, 2012;Hou et al, 2018).…”
