“…These values of the sensitivity and LoD are good and even better than some 2D materials operating at room temperature reported in the literature. 36 The stability is also an important sensing parameter for practical application of a sensor device. The stability of 2D titanium carbo-oxide material was thus investigated by measuring the response towards methanol using our device that has been stored at room temperature.…”

Graphene, as an important member of the twodimensional (2D) class of materials, has been used extensively in a large spectrum of applications due to its remarkable properties. In addition to its properties and its easy modulation through intentional doping with boron (B) and nitrogen (N) heteroatoms leads to the production of graphene derivatives that exhibits a comprehensive arsenal of fascinating properties. More importantly, the different electronegativities of boron and nitrogen heteroatoms bestows graphene with a variety of new and/or improved electromagnetic, catalytic, physicochemical, and optical properties. As a result, doped graphene derivatives have been explored in catalysis, biotechnology, sensors, water purification, and used in many other applications. Nonetheless, there is a shortage of data on the use of B/N co-doped graphene nanomaterials in renewable energy conversion and storage technology. Therefore, this article aims to provide an overview on the recent progress and future aspects of several key applications of B/N co-doped graphene nanomaterials in these areas of energy and storage.

“…For instance, metal oxides doped with Sc [28] and Ag [29] atoms exhibited enhanced sensor performance toward VOCs in contrast with their pure phase. Additionally, it has been reported that B [30], N [31], and Li [32] atoms doping could effectively enhance the selective recognition of carbon-based materials toward VOCs and ammonia. In addition, previous theoretical studies have reported that metal (e.g., Al and Ti)-doped C 2 N were potential sensing materials for certain VOCs [27,33].…”

Two-dimensional (2D) crystalline materials have been regarded as promising sensor materials due to their large specific surface area, high sensitivity, and low cost. In the present work, based on the density functional theory (DFT) method, the sensor performance of novel silicon (Si)-doped nitrogenated holey graphene (SiC2N) toward five typical VOCs (HCHO, CH3OH, C3H6O, C6H6, and C2HCl3) and ammonia were systematically investigated. The results demonstrated that Si doping could effectively decrease the band gap of C2N and simultaneously provide active sites for gas adsorption. Through comprehensive analyses of adsorption energies and electronic properties, the SiC2N was found to exhibit high selectivity for O-containing VOCs (HCHO, CH3OH, and C3H6O) and NH3 via a covalent bond. Moreover, after the HCHO, CH3OH, C3H6O, and NH3 adsorption, the band gap of SiC2N greatly decreases from 1.07 eV to 0.29, 0.13, 0.25, and 0.12 eV, respectively, which indicated the enhancement the conductivity and enabled the SiC2N to be a highly sensitive resistive-type sensor. In addition, the SiC2N possesses a short recovery time. For instance, the recovery time of HCHO desorbed from SiC2N is 29.2 s at room temperature. Our work anticipates a wide range of potential applications of Si-doped C2N for the detection of toxic VOCs and ammonia, and supplies a valuable reference for the development of C2N-based gas sensors.
