Abstract：

Developing　efficient　and　stable　catalysts　for　methanol　oxidation　reaction　(MOR)　is　urgent　for　economic　development　and　energy　scarcity.　Herein,　platinum　(Pt)　catalyst　was　planted　on　carbon　nanotubes　crosslinked　BiOCl　ultrathin　nanosheets　whose　(001)　facets　enriched　with　oxygen　vacancies.　It　has　been　found　that　he　oxygen　vacancies　not　only　can　enhance　the　electrical　conductivity　and　the　adsorption　capability,　but　also　can　stabilize　Pt　due　to　strong　metal-support　interaction.　The　catalyst　exhibits　a　mass　activity　of　2.39　A　mgPt−1,　four　times　higher　than　that　of　the　benchmark　PtC.　Moreover,　its　stability　has　increased　by　54　times　compared　to　PtC.　Such　a　superior　electrochemical　activity　is　attributed　to　the　enhancement　of　OH*　adsorption　dominantly,　which　is　considered　as　the　catalytically　active　species.　Additionally,　the　density　functional　theory　calculation　is　employed　to　explore　the　methanol　oxidation　mechanism　with　assistant　of　in-situ　Raman　test.　The　valuable　formic　acid　may　be　produced　rather　than　CO2,　which　is　expected　to　be　applied　to　direct　methanol　fuel　cells　while　generating　additional　economic　benefits.　©　2025　The　Institution　of　Chemical　Engineers
