1. A catalyst for methane oxidation comprising:
a core structure consisting of a nano-support comprising SiO2 and core nanoparticles comprising V2O5; and
a shell coating layer comprising Al2O3 coated on the core structure,
wherein the core nanoparticles have a particle diameter smaller than that of the nano-support and are coated on the nano-support to form a core structure.
