In this work, electrocatalytic hydrogen evolution reaction (HER) was investigated at new prepared layered double hydroxides (LDH) in acidic solution. NiAl/carbon black (CB) LDH was monitored using x-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM). The substitution of nickel ions with palladium ones was recorded using Energy dispersive X–ray spectroscopy (EDX) .Moreover, the NiAl-LDH/CB and palladium substituted LDH were examined for the HER at different times of substitution. The modified NiAl-LDH/CB/Pd/GCE represented low overpotential of -0.55 V vs Ag/AgCl, Tafel slope of 125 mV/dec, charge transfer coefficient of 0.47, exchange current of 2.56 µA, as well as excellent long-term stability. Moreover, the substitution effect of palladium ions on the modification of prepared LDH GCE was satisfactorily studied for the HER in 0.5 mol L-1 H2SO4 using electrochemical impedance spectroscopy.}, keywords = {Hydrogen evolution reaction,Layered double hydroxides,Carbon black,Pd substitution}, url = {https://hfe.irost.ir/article_284.html}, eprint = {https://hfe.irost.ir/article_284_c63de9a1209d99fd437f2cf64a50edf2.pdf} }
