Latest Advances in 2D Metal-Organic Frameworks: From Synthesis to OER

Efficient oxygen evolution reaction (OER) electrocatalysts are crucial for water splitting and metal-air batteries. Two-dimensional (2D) metal-organic frameworks (MOFs) have become a new class of efficient OER electrocatalysts due to their abundant coordinatively unsaturated metal nodes, large specific surface area, and tunable structures. Moreover, due to inheriting the original microstructure of MOFs and possessing stronger … Read more

FeCoP Sub-Nanosheets for Electrocatalytic Water Splitting

The use of renewable energy for water electrolysis can achieve a green hydrogen production industry chain. However, finding efficient electrocatalysts remains a challenge for green hydrogen production. Here, we constructed sub-nanoscale FeCoP nanosheets with an average thickness of 0.9 nanometers through ultrasonic cavitation-driven two-dimensional self-assembly, followed by phosphorization treatment. Benefiting from rich active sites, enhanced … Read more

Interface Engineering of Iron-Tin-Cobalt Sulfide/Oxide Heterostructure Catalysts for Synergistic Water Splitting

To achieve large-scale hydrogen production through water electrolysis, it is crucial to develop non-precious metal catalysts for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). Here, we prepared a tin, iron, and cobalt-based sulfide/oxide heterostructure catalyst (FeSnCo0.2SxOy/NF) on nickel foam using a solvothermal method. FeSnCo0.2SxOy/NF outperforms IrO2||Pt/C electrolyzers at a current density of … Read more
