Summary: A highly active bi-functional electrocatalyst of Ni2P/FeP heterostructures is constructed and demonstrates the synergistic catalytic mechanism of Ni and Fe species for overall water splitting. Ni enhances the oxygen evolution reaction (OER) performance by promoting the formation of high-valence FeOOH phase, while Ni2P/Ni(OH)2 heterojunction is identified as the high active phase for hydrogen evolution reaction (HER). This study not only develops a near-commercial bifunctional electrocatalyst, but also provides insights into the catalytic mechanism of Ni and Fe.

Summary: Non-noble metal-based electrocatalysts have attracted extensive interest for their low cost, abundance, and high catalytic performance. In this study, an ultrafast thermal method was used to synthesize non-noble metal-based electrocatalysts for water splitting. Nickel oxide and molybdenum carbide on activated carbon felt (Ni-Mo@ACF) exhibited remarkable catalytic activity for hydrogen evolution reaction (HER), while NiFe alloy nanosheets on activated carbon felt (NiFe@ACF) showed excellent catalytic activity for oxygen evolution reaction (OER). Assembling Ni-Mo@ACF as the cathode and NiFe@ACF as the anode resulted in an overall water splitter with a low cell voltage of 1.60V and excellent durability for 36 hours.

Summary: This study reports the synthesis of low-cost and high-durability bifunctional electrocatalysts - nickel-iridium alloy derivative nanochain array electrodes (NiIrx NCs). The nanochains have a self-supported three-dimensional core-shell structure, composed of a metallic NiIrx core and a thin (5-10 nm) amorphous (hydr)oxide film as the shell. NiIrx NCs exhibit bifunctional properties, with higher oxygen evolution reaction (OER) current density and comparable hydrogen evolution reaction (HER) overpotential to 10 wt% Pt/C. Furthermore, NiIr1 NCs show excellent OER and OWS durability. This work provides a promising route for developing effective bifunctional electrocatalysts for overall water splitting (OWS) applications.
