英文摘要	Nanoditches from selective etching of periodically twinned sic nanowires were employed to hinder the migration and coalescence of pd nanoparticles supported on the nanowires, and thus to improve their catalytic stability for total combustion of methane. the results show that the etched pd/sic catalyst can keep the methane conversion of almost 100% while the unetched one has an obvious decline in the catalytic activity from 100 to 82% after ten repeated reaction cycles. the excellent catalytic stability originates from the limitation of the nanoditches to the migration and growth of pd nanoparticles.
