Abstract：

The　interaction　between　metal　and　support　is　an　essential　topic　in　heterogeneous　catalysis.　The　role　of　strong　metal-support　interaction　(SMSI)　between　support　and　metal　particles,　oxide,　or　single　atom　site　in　catalysis　has　been　investigated　recently.　In　this　work,　we　report　a　singly　dispersed　bimetallic　site　(SDBM),　Ir1Ti3,　formed　on　TiO2　support　during　partial　oxidation　of　methane.　The　Ir1Ti3　site　exhibits　an　unusual　＇switch　on/off＇　catalytic　activity　for　partial　oxidation　of　methane　to　produce　syngas,　which　is　due　to　the　strong　interaction　between　TiO2　support　and　in-situ　formed　Ir1Ti3　SDBM　site.　The　high　activity　and　stability　of　the　catalyst　are　also　due　to　the　unique　structure　according　to　the　strong　interaction　effect.　This　work　reveals　the　SMSI　between　oxide　and　SDBM　and　further　impacts　on　catalysis.　©　2022
