摘要
The present invention relates to a composite nanoparticle hydrogen gas sensing material having a core-shell structure of a Pd alloy/oxide semiconductor core-shell structure having excellent selectivity for hydrogen gas, excellent durability, and a low driving temperature, and a semiconductor gas sensor for detecting hydrogen gas using the same. As a result, a shell layer made of metal oxide semiconductor nanoparticles; And a core made of Pd alloy nanoparticles disposed inside the shell layer to improve selectivity for hydrogen gas by absorbing hydrogen gas molecules.
