Abstract：

The　Pt/FeSnO(OH)　5　catalyst　has　been　prepared　by　depositing　Pt　nanoparticles　on　the　synthesized　FeSnO(OH)　5　nanoboxes　and　demonstrates　excellent　performance　towards　methanol　oxidation　reaction　(MOR)　in　direct　methanol　fuel　cells　(DMFCs).　The　Pt/FeSnO(OH)　5　catalyst　exhibits　a　higher　mass　activity　(1182.35　mA/mg　Pt　)　compared　with　Pt/C　(594.57　mA/mg　Pt　)　catalysts.　The　X-ray　powder　diffraction,　field　emission　scanning　electron　microscope,　field　emission　transmission　electron　microscopy,　X-ray　photoelectron　spectroscopy　and　electrochemical　experiments　have　been　employed　to　explore　the　relationships　between　the　crystal　structure　and　electrochemical　properties.　The　increased　activity　and　resistance　of　CO　poisoning　for　Pt/FeSnO(OH)　5　catalyst　can　be　attributed　to　the　strong　interaction　between　the　transition　metal　in　the　hydroxide　and　Pt　and　the　bifunctional　effect.　The　higher　relative　concentration　of　Pt　0　in　Pt/FeSnO(OH)　5　also　contributes　to　the　MOR　activity.　Moreover,　the　charge　transfer　resistance　of　Pt/FeSnO(OH)　5　is　lower　than　that　of　Pt/C.　Therefore,　Pt/FeSnO(OH)　5　has　great　application　prospect　as　a　high-performance　electrocatalyst　in　DMFCs.　©　2018　Fujian　Institute　of　Research　of　the　Structure　of　Matter.　All　right　reserved.
