The construction of two-dimensional (2D) van der Waals (vdW) heterostructures over black phosphorus (BP) has been attracting significant attention to better utilize its inherent properties. sandwich zero-dimensional (0D) noble metals within BP-based vdW can provide efficient catalytic channels, modulating their surface redox potentials and therefore inducing versatile functionalities. Herein, we realize a 2D WS2-Au-BP heterostructure, in which Au nanoparticles are connected between BP WS2 via ionic bonds. ultralow conduction band minimum position, the reduced adsorption energies O2, increased dissociation barrier energy O2– into 2O contribute greatly improving long-term stability air. formation reduce potential target gas molecules, thus enhancing absorption charge transfer. Taking paramagnetic NO2 molecules as representative, stable response magnitude 2.11 100 ppb is achieved for 80 days, far larger than initial responses most materials. A practical sensing system also developed demonstrate real-world implementation. This work provides promising demonstration 0D metal heterostructure simultaneously room-temperature reversible sensing.

Green, efficient, and controllable preparation of In2O3 uniformly modified MoS2 nanoflowers for methanol detection

Applied Physics Letters, Год журнала: 2025, Номер 126(5)

Опубликована: Фев. 3, 2025

In2O3 uniformly modified MoS2 (In2O3/MoS2) nanoflowers were synthesized via a green, efficient, and controllable normal-pressure microwave-assisted route subsequent calcination process, using as substrates. The In2O3/MoS2 nanoflower is composed of extremely thin nanosheets, among which nanoparticles are attached to the nanosheets. Numerous p–n heterojunctions oxygen vacancies present on surfaces nanoflowers. composites exhibited high sensitivity selectivity, along with rapid response recovery methanol vapor at 240 °C. sensors exhibit rates toward methanol, particularly notable time only 15 s for 100 ppm methanol. also demonstrate excellent stability reproducibility, remarkable selectivity This research presents promising approach future design preparation composite detection.
