文摘

Simultaneous treatment of both the loaded metal and the ceria support under plasma led to the generation of clean metal-support interface. This novel synthesis route prevents the tendency of Ni atoms migrating into the bulk of the supports, thereby avoiding a diffused interfacial region. The plasma treated sample showed excellent stability and higher catalytic activity than the thermally calcined sample in dry reforming of methane. The high activity of the plasma treated sample is attributed to the clean metal-support interface generated by exposing both the support and the loaded metal to microwave plasma treatment.
