Abstract：

Ethylene　glycol　oxidation　reaction　(EGOR)　is　a　key　anode　reaction　in　direct　ethylene　glycol　fuel　cells　(DEGFCs).　Herein,　2D　semiconductor　bismuth　tungstate　(Bi2WO6)　nanosheets　are　facilely　prepared　and　used　as　carriers　for　the　deposition　of　platinum　nanoparticles　(Pt　NPs).　The　resultant　material　is　used　as　the　working　electrode　in　the　application　of　DEGFCs.　Due　to　the　excellent　absorption　property　of　Bi2WO6　in　visible　light,　the　optimized　Pt-Bi2WO6　electrode　(Pt　at　20　wt%)　shows　improved　catalytic　activity　and　stability　with　visible-light　illumination.　The　current　density　using　the　Pt-Bi2WO6　electrode　reaches　492.5　mA　mg−1Pt　with　visible-light　irradiation,　which　is　about　4.2　fold　higher　in　comparison　with　the　same　electrode　in　dark　conditions.　This　2D　sheet-like　support,　together　with　the　visible-light　response　of　Bi2WO6,　induces　the　deposition　of　ultra-small　sizes　of　Pt　(5.4　nm)　and　the　synergistic　effect　of　electrocatalytic　and　photocatalytic　ethylene　glycol　oxidation,　thus　greatly　improving　the　photoelectric　catalytic　property　of　EGOR.　©　2019　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
