High-efficiency overall alkaline seawater splitting: using a nickel-iron sulfide nanosheet array as a bifunctional electrocatalyst

Jie Chen et al.

Summary: The use of nickel-iron sulfide nanosheet array on nickel foam as a bifunctional electrocatalyst demonstrates high-performance and cost-effective electrolysis of seawater for hydrogen production. It delivers a current density of 500 mA cm(-2) at overpotentials of 300 and 347 mV for the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) in alkaline seawater respectively. Moreover, it only requires a cell voltage of 1.85 V to drive 500 mA cm(-2) in a two-electrode electrolyzer, and shows strong stability for at least 50 hours of electrolysis in alkaline seawater, outperforming recently reported catalyst electrodes for seawater splitting.

Ligand Modulation of Active Sites to Promote Electrocatalytic Oxygen Evolution

Wenzhong Huang et al.

Summary: This study proposes a feasible ligand modulation strategy to boost the oxygen evolution reaction (OER) catalytic activity of cobalt-iron oxyhydroxide ((Fe,Co)OOH). By reducing the orbital overlap between the Fe/Co 3d and O 2p, the adsorption to oxygen-containing intermediates is weakened, which facilitates the O-2 desorption. The ligand-modulated (Fe,Co)OOH exhibits excellent OER performance with low overpotentials and high durability.

Synergetic Metal Defect and Surface Chemical Reconstruction into NiCo2S4/ZnS Heterojunction to Achieve Outstanding Oxygen Evolution Performance

Jing Sun et al.

Summary: Defect and interface engineering are effective strategies to improve the activity of metal sulfides, but the practical application is limited by low conductivity and volume fluctuation. By anchoring Zn-defective ZnS nanoparticles on the surface of NiCo2S4 nanosheets, the NiCo2S4/ZnS hybrids exhibit outstanding oxygen evolution performance with an ultra-low overpotential of 140 mV. The anchored ZnS nanoparticles inhibit volume expansion of NiCo2S4 nanosheets during cycling.
