Abstract:
We report here robust electrocatalysts from metal doped W18O49 nanofibers (NFs) for high-efficiency hydrogen evolution. By tuning Pd dosages, the optimal 5 at% Pd doped W18O49 NFs yield an onset overpotential of only 65 mV and exchange current densities up to 2.36 × 10-3 mA cm-2. Moreover, the resultant electrocatalyst is relatively stable during persistent operation.
