Reactions of Noble Metal Species with Methane in Gas-Phase

Noble metals have been identified to exhibit excellent performance in methane chemistry. Gas phase study of chemical reactions between noble metal species and methane permits to uncover the active sites and elementary reactionmechanisms involved in condensed-phase catalytic reactions at a strictly molecular level. In this review, we summarize the recent progress in activation and transformation of methane by noble metal species including single atoms, atomic ions, cluster ions, hydrides, halides, oxides, metal-methyl complexes, and heteronuclear clusters. Themechanistic difference of methane activation bydifferent noble metal systems is also discussed in detail.
