Abstract Traditional metal oxide semiconductor gas sensors are facing significant challenges for portable devices and integration due to large power consumption caused by high working temperature. 2D nanomaterials with specific surface areas, rich active sites, tunable electrical properties proved be promising candidates room‐temperature sensors. However, several disadvantages including weak response, sluggish response/recovery kinetics, poor selectivity still need overcome high‐performance...
Here we describe a two-step aerosol-assisted chemical vapor deposition (AACVD) synthesis method for the fabrication of Ag nanoparticles (NPs) decorated WO3 nanorods (NRs), evaluating use different organometallic silver precursors. Physical property characterization techniques including XRD, SEM, TEM, and XPS were carried out to investigate composition morphology pristine NRs functionalized with NPs. The results showed that uniform obtained length 600 nm several μm diameter 100–200 nm, NPs...
The influence of annealing temperature on the microstructure and H 2 sensing properties Pd-doped SnO sputtered thin films were investigated.The as-deposited film was amorphous would crystallize to tetragonal structure when above 350°C.The composed columnar grains.Both crystallite size grain increased with an increase in temperature.H measurements showed that gas sensors based these obtained peak response 1000 ppm at operating 100°C a good reversibility.The annealed 450°C highest .The...
