文摘

Two types of Pd layers were electrodeposited on Ti2AlC. Analysis by SEM and AFM showed 3D islands of Pd on sample (2). Hydrogen evolution was studied on all samples by polarization and EIS measurements. Overvoltage for the HER on sample (2) was the lowest: −50 mV at −50 mA cm−2. Specific jo on sample (2) was −35.83 mA mg−1 with Pd loading of 0.0254 mg cm−2.
