The stability of electrocatalysts during the hydrogen evolution reaction (HER) is vital for efficient production of hydrogen energy. Herein, we demonstrate that silver nanowire aerogel-based support (AABS) could facilitate the construction of HER catalysts with extraordinary long-term stability. A full nanostructure catalyst of nickel phosphide based formed on AABS (Ni 2 P−Ni 5 P 4 @ AABS) was prepared to achieve an overpotential of 687 mV (without iR compensation) for HER at the current density of 1 A cm −2 in 0.5 M H 2 SO 4 . Excitingly, the stable HER performance was kept for 42 days during the long-term stability (i−t) test at high current density (0.5−1 A cm −2 ). The excellent HER performance of the Ni 2 P−Ni 5 P 4 @AABS catalyst is attributed to rapid electron transport pathways, numerous more accessible active sites, and support induced enhanced catalytic activity. The support effect was highlighted by a proposed phenomenological two-channel model for electron transport, which provides fresh insights into the design strategy for energy storage and delivery.
