A sigh-performance hydrogen gas sensor based on Ag/Pd nanoparticle-functionalized ZnO nanoplates

Abstract

The Ag/Pd–ZnO nanoplates exhibit 47 folds enhancement response to hydrogen gas. This demonstrates the catalyst phenomenon of Ag/Pd nanoparticles on the hydrogen sensing performance.

Enhanced acetone gas-sensing characteristics of Pd–NiO nanorods/SnO2 nanowires sensors

“…The mass of Pd nanoparticles used in this process can be calculated through the precursor solutions used in previous reports of our group. 37 The Pd–NiO nanorods colloidal solutions were then dropped on the surface of SnO 2 nanowire devices to form SnO 2 /Pd–NiO sensors. The fabricated sensors were then annealed at 500 °C for 2 h to evaporate the solvent and to reduce the defects.…”

Graphene-Wrapped ZnO Nanocomposite with Enhanced Room-Temperature Photo-Activated Toluene Sensing Properties

“…Functionalized nanoscale ZnO with metal nanoparticles, such as Pd and Pt nanoparticles [ 10 , 11 ], has been applied to test H 2 and NH 3 gases at room temperature. However, its sensing sensitivity and response were low, and did not meet the requirements of practical applications for monitoring environmental gas pollution.…”
