The gas sensing performance of borophene/MoS2 heterostructure

2D boron nanosheet architectonics: opening new territories by smart functionalization

“…Shen et al theoretically designed a borophene/MoS 2 heterostructure and investigated the adsorption behaviors towards small gas molecules (CO, CO 2 , NO, NO 2 and NH 3 ) on the borophene surface. 130 The MoS 2 serves as a substrate to stabilize the borophene and modify its electronic structure to tune the gas adsorption performance. The results indicated that the CO/NO/NO 2 /NH 3 molecules can be adsorbed onto the composite by B-C/N bonds.…”

Borophene as a rising star in materials chemistry: synthesis, properties and applications in analytical science and energy devices

“…85 DFT calculations were performed to estimate the adsorption energies of several gases on the borophene/MoS 2 heterostructure. 86 The other four compounds (except CO 2 ) bind with borophene. It may be termed physisorption due to the little interaction between borophene and the CO 2 molecule.…”

Transition Metal Dichalcogenides for the Application of Pollution Reduction: A Review

“…The work concluded that Ti doping strategy improved the sensitivity of both materials towards CO and NO gas detection. Another recent work from Shen et al [168] provided a study of using a borophene/MoS 2 heterostructure to detect small gas molecules (CO, NO, NO 2 , and NH 3 ), which exhibited different resistive properties towards these molecules when changing voltage direction (see Figure 5). Modulation of MoS 2 by antisite doping and strain also showed improved gas detection sensitivity [169].…”
