Abstract：

Ruthenium　(Ru)　nanoparticles　(∼3　nm)　with　mass　loading　ranging　from　1.5　to　3.2　wt　%　are　supported　on　a　reducible　substrate,　cerium　dioxide　(CeO2,　the　resultant　sample　is　called　Ru/CeO2),　for　application　in　the　catalytic　combustion　of　propane.　Because　of　the　unique　electronic　configuration　of　CeO2,　a　strong　metal-support　interaction　is　generated　between　the　Ru　nanoparticles　and　CeO2　to　stabilize　Ru　nanoparticles　for　oxidation　reactions　well.　In　addition,　the　CeO2　host　with　high　oxygen　storage　capacity　can　provide　an　abundance　of　active　oxygen　for　redox　reactions　and　thus　greatly　increases　the　rates　of　oxidation　reactions　or　even　modifies　the　redox　steps.　As　a　result　of　such　advantages,　a　remarkably　high　performance　in　the　total　oxidation　of　propane　at　low　temperature　is　achieved　on　Ru/CeO2.　This　work　exemplifies　a　promising　strategy　for　developing　robust　supported　catalysts　for　short-chain　volatile　organic　compound　removal.　©　2018　American　Chemical　Society.
