The loading of noble-metal nanoparticles (NPs) is an effective approach for the enhancement H2 sensing performances, although there have been rare reports focused on effect facets in performance. catalytic and adsorption performance nanocrystals mainly determined by their exposed facets, while gas sensors strongly correlated to reaction between gases sensor materials. Hence, it very important study different facets-exposed nanoparticles. In this study, a set shape-controlled Pd NPs prepared loaded onto ZnO nanorods, nanoparticle-loaded 250 ppm has detected. results indicate that cubic NPs-loaded shows higher faster response than octahedral spherical Pd-loaded owing stronger enclosed (100) (111) facets. also exhibits better selectivity repeatability towards H2.
