Published: Jan. 19, 2023

Abstract Water utilization is accompanied with the development of human beings, whereas gaseous moisture usually regarded as an underexploited resource. The advances highly efficient hygroscopic materials endow atmospheric water harvesting intriguing solution to convert into clean water. discovery hygroelectricity, which refers charge buildup at a material surface dependent on humidity, and following moisture‐enabled electric generation (MEG) realizes energy conversion directly outputs electricity. Much progress has been made since then optimize MEG performance, pushing forward applications practical level. Herein, evolvement are systematically summarized in chronological order. optimization strategies discussed comprehensively evaluated. Then, latest presented, including high‐performance powering units self‐powered devices. In end, perspective future given for inspiring more researchers this promising area.

Edge‐Enriched Mo₂TiC₂T_x/MoS₂ Heterostructure with Coupling Interface for Selective NO₂ Monitoring

Advanced Functional Materials, Journal Year: 2022, Volume and Issue: 32(39)

Published: June 25, 2022

Abstract Endowed with rich terminal groups, good electrical conductivity, and controllable structure, transition metal carbides/nitrides (MXenes) have attracted extensive attention for potential application in gas sensor, but long‐standing challenges of the MXenes (titanium carbide as representative) are their limited selectivity sensitivity. Herein, a high‐active double transition‐metal titanium molybdenum (Mo 2 TiC T x ) superstrong surface adsorption (−3.12 eV) NO molecule is proposed, it further coupled disulfide (MoS by interface modulation to construct an edge‐enriched heterostructure. Due synergistic effect strong adsorption, sites, coupling Mo /MoS composite, as‐fabricated sensor exhibits outstanding response toward high against various interference gases, which well supported density functional theory calculations. Meanwhile, sensitivity 7.36% ppm −1 , detection limit 2.5 ppb, reversibility at room temperature. A portable, wireless monitoring system demonstrated leakage searching dangerous warning based on sensor. This work facilitates sensing MXenes, provides avenue development environmental safety assurance.
