•Novel FeP nanorods electrocatalyst was successfully synthesized via a hard template strategy.•The FeP nanorods exhibit excellent activity towards hydrogen evolution reaction.•The catalyst shows superior stability during operation in acid conditions.
Herein for the first time we report a novel approach to prepare well-controlled iron phosphide nanorods (FeP NRs) via low-temperature phosphidation of Fe salt with a porous anodic aluminum oxide (AAO) template. The as prepared FeP NRs exhibit high catalytic activity toward hydrogen evolution reaction (HER) in acidic solutions, showing an onset potential of ∼45 mV, a Tafel slope of 55 mV/dec and nearly 100% Faradaic yield (FY) with good stability. Additionally, the catalyst can deliver current density of 2 and 10 mA/cm2 for HER with low overpotentials of 67 and 120 mV, respectively. Up to date the FeP NRs should be the inexpensive electrocatalyst while offering high activity toward HER, thus holding a great promise for practical applications for water electrolysis in large scale production.
