摘 要:Direct liquid fuel cells(DLFCs)are promising clean energy conversion devices for their high energy density,low environmental pollution,and convenient transportation and ***,the commercialization of DLFCs is still limited by the lack of highly active and stable catalysts for the anodic oxidation of liquid ***,a new class of ultrathin PtRu nanowires(NWs)with a diameter of 1.1nm was synthesized via a colloidal chemistry *** as-made ultrathin PtRu NWs can not only expose large active sites but also enhance the kinetics of methanol oxidation reaction,which was confirmed by the in situ Fourier transform infrared(FTIR)***,ultrathin PtRu NWs exhibit greatly boosted activity and stability for methanol and ethanol oxidation reactions in an alkaline medium.
