An efficient hydrogen gas sensor based on hierarchical Ag/ZnO hollow microstructures

Sonalika Agarwal et al.

Summary: The design of hierarchical zinc oxide (ZnO) microstructures modified with silver (Ag) nanoparticles has been proven effective in enhancing hydrogen gas sensing performance. The Ag/ZnO hollow microstructures showed superior sensitivity, fast response and recovery time, as well as good stability, even at low hydrogen gas concentrations. This enhancement in sensing performance is attributed to the chemical and electronic sensitization effect of Ag nanoparticles, leading to a more sensitive sensor with improved selectivity.
