| description | In this study, SnO<sub>2</sub>-Pd nanoparticles(NPs) were made with an in situ synthesis-loading method. The in situ method is to simultaneously load a catalytic element during the procedure to synthesize SnO<sub>2</sub> NPs. SnO<sub>2</sub>-Pd NPs were synthesized by using the in situ method and were heat-treated at 300 °C. As a result, tetragonal structured SnO<sub>2</sub>-Pd NPs, having an ultrafine size of less than 10 nm and a uniformly distributed Pd catalyst in the SnO<sub>2</sub> lattice, were well made and a gas sensitive thick film with a thickness of c.a. 40 μm was well fabricated by using the NPs. Gas sensing characterization for CH<sub>4</sub> gas indicated that the gas sensitivity, R<sub>3500</sub>/R<sub>1000</sub>, of the thick film consistent with SnO<sub>2</sub>-Pd NPs synthesized with the in situ synthesis-loading method, followed by heat-treatment at 500 °C, was enhanced to 0.59. Therefore, the in situ synthesis-loading method is available for synthesis of SnO<sub>2</sub>-Pd NPs for gas sensitive thick film. |
