The　preparation　of　palladium　(Pd)　from　a　water-and　air-stable　room-temperature　ionic　liquid,　1-ethyl-3-methylimidazolium　trifluoromethanesulfonate　([emim]OTf),　was　investigated.　Cyclic　voltammetry　was　applied　in　examining　the　electrochemical　behavior　of　Pd　(II)　chloride　and　in　identifying　the　current　density　for　the　electrodeposition　of　Pd.　The　optimum　parameters　of　Pd　electrodeposition　were　obtained　through　single-factor　experiments.　Surface　morphology　and　elemental　composition　of　final　products　were　probed　by　scanning　electron　microscopy　and　energy-disperse　spectrometer　analyses.　The　deposition　of　crystalline　Pd　metals　was　confirmed　by　X-ray　diffraction　(XRD).　Results　demonstrated　that　1-ethyl-3-methylimidazolium　trifluoromethanesulfonate　was　a　potential　electrolytic　medium　for　electrodepositing　high-purity　Pd　at　room　temperature.
