In this work, we present an approach for utilizing pristine Bi2S3 as a sensing material the detection of NO2 gas at room temperature. Spanish oyster-like hierarchical nanostructures, with diameter 832 nm and Brunauer–Emmett–Teller (BET) surface area 20.56 m2/g, were grown using [Bi{S2P(O(Pr)2)3}] complex via optimized, one-step, low-temperature, in situ solvothermal process. contrast, spin-coating method resulted impurities even after annealing step. X-ray diffraction (XRD), Raman, selected (SAED), high-resolution transmission electron microscopy (HRTEM) analyses confirmed orthorhombic bismuthinite phase calculated band gap 2.82 eV. The Bi2S3-based sensor exhibited exceptional sensitivity selectivity toward NO2, surpassing other gases such CO2, NH3, H2S, C2H6O Specifically, demonstrated high response 39.4%, rapid response/recovery times (14/257 s), excellent repeatability, stability (30 days) under 100 ppm exposure. enhanced performance temperature is attributed to competitive adsorption on structure Bi2S3, facilitating increased charge transfer.

The epitaxial growth of heterojunctions can reduce interface defects and enhance the stability crystal structures. However, a higher lattice mismatch cause local distortions at interface, resulting in relaxed strains that eventually evolve into structural defects. Herein, nearly zero-mismatch semicoherent was formed with (0.3%) by CsPbBr3 on CdS quantum dots (QDs), leading to strain-free interface. Results demonstrated CdS/CsPbBr3 heteronanocrystals (HNCs) had excellent high photocatalytic performance compared CsPbBr3. Theoretical calculations show Br–Cd bond forms strong electron coupling, which not only facilitates rapid transfer but also provides better stability. Compared individual nanocrystals (NCs), HNCs exhibited 2.1 times activity. It suggests have potential application value energy environmental fields.
