摘要

The local structure of In/SiO2, which is a potential catalyst for the non-oxidative coupling of methane, was investigated by using in situ In K-edge X-ray absorption fine-structure analysis. During the activation process, the In/SiO2 catalyst underwent several metamorphosis-like transformations of its structure before final conversion to the active phase.
