Obtaining a Hybrid Electrode based on Imidazonium Ion- terminated and Metallic Nano-clusters for Battery Electrode use

In the present work, we focused on the grafting of thin film positively charged based on ionic liquids (LIs) on a glassy carbon electrode (GC), then functionalized with metal nanoparticles (Pt or Pd). The SEM obtained images confirm the modified electrode. Interestingly, the catalytic performances of hydrogen evolution reaction (HER) are improved for both prepared electrodes (GC/LI/Pt, GC/LI/Pd), especially the latest one containing palladium. It seems that the ionic layer presence displays an increase catalytic, which is probably due to the synergistic effect existence between the grafted ionic layer and the metallic nanoparticles.
