Abstract：

Micron-porous　metal　wires　have　attracted　great　attention　because　of　their　important　application　for　fiber-shaped　biosensor,　energy　and　catalysis　devices.　Herein,　we　report　a　novel　direct-flame　approach　for　in-situ　sculpturing　micron-porous　structures　on　the　surfaces　of　Ag　wire　precursors.　The　heat　and　H2–CO–O2　mixed　gas　generated　by　the　flame　of　ethanol　ascribe　to　the　fast　creation　of　micron-pores　on　the　Ag　wires.　This　process　is　simple,　green　and　cost-effective,　avoiding　the　use　of　sacrificial　materials　or　templates　required　by　conventional　techniques.　The　obtained　micron-porous　Ag　wire　(MPAW)　is　useable　as　a　high　performance　self-supported　microelectrode　for　fiber-shaped　electrochemical　supercapacitors.　Moreover,　the　MPAW　is　applicable　as　a　highly　active　and　reusable　microprobe　for　surface-enhanced　Raman　scattering.　©　2019　Elsevier　B.V.
