Summary: Porous Ag@ZnO hollow nanocages (HNCs) were synthesized using Ag@ZIF-8 as a template, resulting in mesoporous hollow nanostructures with Ag nanocatalysts evenly dispersed. Both pure ZnO HNCs and Ag@ZnO HNCs displayed UV-activated ethanol sensing responses at 180 degrees C. Ag@ZnO HNCs exhibited a higher ethanol sensing response compared to ZnO HNCs, attributed to the creation of Schottky junctions, improved light utilization, and the local surface plasmon resonance effect of Ag nanoparticles.

Summary: The study utilized pristine and Pd-decorated 2D ZnO nanosheets for hydrogen detection, showing positive effects of Pd decoration on response, sensing temperature, and selectivity. Gas sensing experiments demonstrated that the Pd-decorated nanosheet sensor successfully detected low concentrations of hydrogen gas and could also detect hydrogen in a gaseous mixture with benzene. Furthermore, the presence of Pd-ZnO heterojunctions, formation of PdHx, and high catalytic activity of Pd were found to contribute to the sensing enhancement of the Pd-decorated sensor.

Summary: In this study, two-dimensional (2D) ZnO@ZIF-8 porous nanosheets (PNSs) heterostructures were prepared to effectively improve the sensitivity of semiconductor gas sensors for ethanol detection. The ZnO@ZIF-8-24 exhibited an enhanced response and high selectivity towards 50 ppm ethanol at 240 degrees C compared to ZnO. Additionally, at low concentration (5 ppm), ZnO@ZIF-8 had a better response than ZnO. The enhancement was attributed to the inhibition of self-stacking of two-dimensional porous nanosheets by ZIF-8 nanoparticles, increasing the exposure of active sites.
