The　synthesis　method　of　precious　metal　catalysts　would　affect　the　electronic　metal-support　interaction　(EMSI)　of　catalysts,　which　further　affected　the　catalytic　activity.　In　this　paper,　Co3O4　was　obtained　as　support　by　the　pyrolysis　of　ZIF-67　as　a　template　sacrificial　agent,　and　Pt　species　were　loaded　by　three　different　reduction　methods.　Among　them,　the　catalyst　produced　by　the　NaBH4　reduction　method　possessed　the　best　activity　with　T90　of　168　degrees　C.　Through　a　series　of　characterization　and　experiments,　it　was　found　that　the　EMSI　of　the　catalyst　was　optimized　by　this　synthesis　method,　which　led　to　electron　transfer　among　Pt　species　and　Co3O4.　The　catalysts　also　exhibited　excellent　water　resistance,　stability,　and　recycling　performance.　The　possible　degradation　mechanism　of　toluene　was　also　revealed　by　in　situ　DRIFTS　and　GC-MS.　This　paper　provided　ideas　for　the　construction　of　catalysts　and　a　theoretical　reference　for　the　relevant　verification　of　EMSI.
