The　combination　of　different　semiconductors　to　form　a　heterojunction　plays　an　important　role　for　exploring　new　visible-light-driven　electrocatalysts.　Herein,　a　two-dimensional　(2D)　Bi2WO6/La-2　Ti2O7　(LTO)　heterojunction　has　been　synthesized　and　to　be　as　carrier　of　Pt　nanoparticles.　Subsequently,　electrocatalytic　activity　and　stability　of　the　as-obtained　Pt-Bi2WO6/LTO　has　been　evaluated　in　methanol　oxidation　reaction　(MOR)　under　the　action　of　visible　light　and　electricity.　Results　indicate　that　Pt-Bi2WO6/LTO　sample　displays　excellent　catalytic　performance　and　stability　with　assistance　from　visible　light.　Under　identical　conditions,　the　current　intensity　of　MOR　on　the　Pt-Bi2WO6/LTO　modified　electrode　is　found　to　reach　1409　mA　mgF(pt)(-1)　,　which　is　3.92　times　higher　than　the　measured　Pt-Bi2WO6　modified　electrode　(359.8　mA　mgFpt(-1)　).　In　addition,　the　current　density　of　MOR　on　Pt-Bi2WO6/LTO　electrode　decreases　by　2.85%　after　scanning　for　300　cycles.　Furthermore,　Pt-Bi2WO6/LTO　is　6.99　times　more　resistant　to　poisoning　than　the　Pt-Bi2WO6　electrode　determines　by　chronopotentiometry　under　visible　light　illumination.　The　presented　results　indicate　that　a　Pt-Bi2WO6/LTO　nanocomposite　is　a　viable　alternative　photo-electric　catalyst,　providing　a　potential　new　basis　for　the　future　development　of　catalysts　in　fuel　cell　reactions.　(C)　2019　Elsevier　Inc.　All　rights　reserved.
