Ultra-fast and highly selective room-temperature formaldehyde gas sensing of Pt-decorated MoO3 nanobelts

Formaldehyde is one of the most serious threats to human health owing to the wide-spread of indoor decoration of modern buildings in recent years. The online monitoring of formaldehyde concentration of the indoor environment has become an urgent issue in modern society. In this work, an ultrafast and highly selective room-temperature formaldehyde gas sensor based on the semiconductor nanomaterials was developed. The Pt-decorated MoO3 nanobelts...
