A confined MnO 2 catalyst with MnO 2 nanoparticles entrapped in TiO 2 nanotube was synthesized through vacuum‐assisted impregnation method. Due to the confinement effect of TiO 2 nanotube, the electron density distribution between the exterior and interior nanotube surface is modulated. As such, the confined MnO 2 can facilitate the formation and migration of active oxygen species in the catalyst. The catalyst exhibits the enhanced activity in the catalytic combustion of butane, and the reaction temperature is significantly lowered. This result demonstrates that the confined MnO 2 in TiO 2 nanotube can serve as a cost‐effective catalyst for the elimination of VOCs from the air.
