چکیده انگلیسی
Moreover, X-ray analysis showed that Mn3O4 and Co3O4 nanoparticles were formed in tetragonal and cubic symmetry respectively. The SEM image revealed that a dominate morphology of product has cubic nanowires shape with an average diameter in range 38-43â¯nm. Furthermore, we observed that influence of temperature was very important in the nanowire formation process. Electrochemical hydrogen evolution reaction (HER) of synthetic composite was evaluated and the over potential of HER was calculated about 110â¯mV with low Tafel slope equal to 42â¯mVâ¯decâ1, which was comparable with amounts reported transition metal dichalcogenides with satisfying durability.
