Highly stable performance of catalytic methane dehydrocondensation towards benzene on Mo/HZSM-5 by a periodic switching treatment with H2 and CO2

Excellent stability and high catalytic activity of methane dehydrocondensation towards benzene and naphthalene on Mo/HZSM-5 were achieved at 1023–1073 K by a periodic H2 or CO2 switching operation, owing to the efficient removal of coke deposition.
