Palladium has long been explored for use in gas sensors because of its excellent catalytic properties and unique property forming hydrides the presence H2. However, pure Pd-based usually suffer from low response a relatively high limit detection. nanosheets (PdNS) are particular interest sensing applications due to their surface area electrical conductivity. Here, we demonstrate design fabrication low-cost PdNS-based dual room-temperature detection H2 CO over wide concentration range. We...

We present a unique three-dimensional palladium (Pd)-decorated crumpled reduced graphene oxide ball (Pd-CGB) nanocomposite for hydrogen (H2) detection in air at room temperature. Pd-CGB nanocomposites were synthesized using rapid continuous flame aerosol technique. Graphene reduction and metal decoration occurred simultaneously high-temperature reducing jet (HTRJ) process to produce Pd nanoparticles that below 5 nm average size uniformly dispersed the structure. The sensors made from these...

Rapid and sensitive H2 detection is important because of its low threshold for the formation explosive mixtures in air (∼4%).
