Impact of Pd nanoparticle loading method on SnO2 surface for natural gas detection in humid atmosphere
To improve the sensor response to low concentrations of methane (CH4) at low operating temperatures in humid atmospheres, we prepared Pd-loaded SnO2 (Pd-SnO2) nanoparticles via two different Pd-loading processes:...
