Screw-like PdPt nanowires as highly efficient electrocatalysts for methanol and ethylene glycol oxidation

Abstract

Screw-like PdPt nanowires exhibit enhanced performance towards MOR and EGOR attributed to the unique structure and synergetic effect of the catalysts.

Facile Synthesis Of Composition‐Controllable PtPdAuTe Nanowires As Superior Electrocatalysts For Direct Methanol Fuel Cells

“…Meanwhile, the reserves of traditional fuels are declining, which brings severe energy and environmentali ssues. [1] Therefore, it is urgent to seek the clean and renewable sources to replacef ossil fuels. Recently,h ydrogen and liquid alcohol fuels have been considered ass ubstitutes.…”

“…[7][8][9] In recent years, am ass of binary or ternary Pt-based alloy nanomaterials have been reported. [1,[10][11][12] For example, Tang et al [1] synthesized binaryP tPd NWs with screwlike surfacethrough electrochemical deposition method, and different compositionsa nd morphologies PtPd alloys were obtained by regulating the upper potential limit. The PtPd NWs not only reducet he amount of Pt, but also boost their electrochemical performance to methanol and ethylene glycol oxidation.…”

“…To date, al arge number of excellent achievements on Ptbased NWs have been reported. [1,9,15,16] In addition, precise design and control the composition and size of Pt-based NWs could dramatically decrease the amount of Pt and increase the utilization of Pt reactive sites. Binary and ternary alloy nanomaterials generated by combining Pt with Pd and Au have been reporteda sa node catalysts for DAFCs.…”

“…[21] In addition, the bifunctional mechanism, electronic and synergistic effects between different metals in Pt-based nanomaterials could enhance electrocatalytic performance and stability for methanoloxidation. [22,23] The methodsf or preparing nanomaterials mainlyi nclude chemicalr eduction method, [24] template approach, [25] solvothermal( hydrothermal)m ethod, [26] electrochemical deposition, [1] and electrospinning, [23] etc. Amongt hem, the template methodi saversatile strategy to preparen anocatalysts with variouss tructural morphologies.…”
