dc.description.abstract | Herein, we examine the application of mesoporous cobalt phosphide (meso-CoP) prepared by a hard-templating method as a novel non-precious electrocatalyst for the oxygen evolution reaction (OER). The obtained meso-CoP exhibits a relatively low overpotential (0.30 V at 10 mA cm−2), a decent Tafel slope (81 mV dec−1), and good long-term stability, performing better than its bulk counterpart and many state-of-the-art Co-based OER electrocatalysts. The high electrocatalytic performance of the meso-CoP toward OER is attributed to two key factors: (1) a large accessible active surface which endows the meso-CoP with numerous active sites for water oxidation; (2) a well-organized mesoporous structure which expedites the electron/ion transfer and mass transport, thereby significantly enhancing the OER kinetics. This work will provide guidance for designing inexpensive high-performance electrocatalysts with exquisite mesostructures for potential applications in commercial water-splitting technology. | |
