In　this　paper,　Pt　nanoparticles　are　deposited　on　nickel　foam　by　the　mild　displacement　reaction　occurring　at　room　temperature.　Thus　prepared　nickel　foam　supported　Pt　is　used　as　efficient　and　highly　flexible　counter　electrode　of　dye-sensitized　solar　cells　(DSSCs),　the　performance　of　which　can　be　enhanced　by　simply　prolonging　the　reaction　time.　The　results　denote　that　when　the　reaction　time　is　just　40　min,　the　nickel　foam　supported　Pt　has　exhibited　better　catalytic　activities　than　the　commonly　used　polyethylene　naphthalate　polymers　supported　Pt.　The　deposition　of　Pt　is　investigated　by　the　scanning　electron　microscopy,　X-ray　photoelectron　spectroscopy,　energy　dispersive　spectroscopy　and　UV-Vis　spectra,　and　the　catalytic　activities　of　fabricated　flexible　Pt　counter　electrode　are　verified　by　electrochemical　impedance　spectra　and　cyclic　voltammetry　curves.　The　approach　proposed　here　is　facile　and　can　be　used　for　the　large　scale　fabrication　of　efficient　flexible　counter　electrode　in　DSSCs.
