Highly sensitive and selective H2 sensing by ZnO nanofibers and the underlying sensing mechanism

[Display omitted] •Exceptional hydrogen gas sensor fabricated with ZnO nanofibers.•ZnO nanofibers show outstanding, selective H2 response.•Semiconductor-to-metal transition in the presence of H2 is the responsible mechanism. We report, and propose a mechanism for, the exceptional hydrogen gas (H2) s...
