Conversion of methane to C(2) and C(3) hydrocarbons over TiO(2)/ZSM-5 core–shell particles in an electric field

Catalytic conversion of methane (CH(4)) to light olefins is motivated by increasing recoverable reserves of methane resources, abundantly available in natural gas, shale gas, and gas hydrates. The development of effective processes for conversion of CH(4) to light olefins is still a great challenge. The interface of ZSM-5 zeolite and TiO(2) nanoparticles is successfully constructed in their core–shell particles via mechanochemical treatment with high shear stress. The oxidative coupling of methane at a low temperature under application of an electric field may be induced by the O(2) activation via electrons running through the surface of TiO(2) located at the interface of TiO(2) and zeolite particles. Moreover, C(3)H(6) was also produced by the ethylene to propylene (ETP) reaction catalyzed by Brønsted acid sites in the ZSM-5 zeolite within core–shell particles.
