High-temperature hydrogen sensor based on platinum nanoparticle-decorated SiC nanowire device

- A single SiC nanowire high-temperature gas sensor was fabricated.
- The surface of SiC nanowire was decorated with Pt nanoparticles as a hydrogen catalyst.
- A high H2 sensing performance such as fast response time (3 s) and recovery time (45 s) was demonstrated.
- The Pt catalytic hydrogen sensing mechanism of SiC nanowire sensor was discussed.
