摘要
Methane is an attractive C1 resource for production ofvalue-added chemicals. The current industrial utilizationof methane involves indirect route via preliminary oxi-dation to syngas （a mixture of CO and H2） that can beconverted to desired products [1]. Such two-stage processis energy-intensive. Considerable efforts have been de-voted to developing catalytic processes that can efficientlyand directly transform methane through oxidative ornon-oxidative pathways [2,3].
