초록

Au/SnO2 core-shell structure nanoparticles (NPs) were synthesized by microwave hydrothermal method, and the effect of working temperature on sensitivity of Au/SnO2 core-shell NPs for CO gas was investigated. The SnO2 shell layer was consisted of SnO2 primary particles with 4.5 nm diameter. The response of Au/SnO2 core-shell NPs for CO gas was maximized at the working temperature of 350 while the sensitivity increased with decreasing the working temperature due to the low grain size effect of SnO2 NPs on the response of CO gas.
