The self-limiting Cabrera-Mott oxidation reaction on metal surfaces provides an effective pathway for synthesizing atomically thin 2D oxide. Inspired by this reaction, it is proposed that solid bismuth metals can react with dissolved oxygen and water molecules in aqueous environment, forming ultrathin oxyhydroxide layer their surfaces. lattice mismatch between the surface underlying pure enables mechanical exfoliation of detached nanosheets. Moreover, sulfurization interaction H2S expands applicability solid-liquid interfacial reactions realizing oxysulfide, effectively tuning electronic bandgap energy, work function, band position. Given its good photoresponse from blue to UV light, optoelectronic gas sensing performances oxysulfide are investigated. Under purple light irradiation, Bi2O1.12S1.88-based sensor exhibits excellent response factor 48.5% toward 10 ppb NO2, which lowest detection limit reported compounds-based so far. This a novel facile synthesis approach simultaneously demonstrates substantial potential high-performance sensing.

Defect and facet engineering are the two effective approaches to tune surface reactivity of metal-oxide-based sensing materials. Here, oxygen vacancies defective WO3 nanosheets with exposed (002) crystal [D-WO3-(002)] were obtained by a simple hydrothermal–hydrogenation process. The results revealed that D-WO3-(002)-based acetone sensor exhibits excellent comprehensive gas sensitive performance: low limit detection (0.5 ppm), wide range 0.5–100 ppm (S = 2.8∼45.6), high selectivity, fast response–recovery, repeatability. outstanding gas-sensing performance is attributed synergistic effects dominant defect vacancy structure, which effectively improved monoclinic nanosheets. For highly performance, this work demonstrates tremendous potential application prospect for environmental monitoring non-invasive diagnosis diabetes.
