Amorphization engineering of Ni-cysteine coordination composition for urea electro-oxidation at large current density.

Unavoidable oxygen evolution reaction (OER) and the relatively high potential to form real active sites of Ni species severely decrease the efficiency of urea-assisted hydrogen generation facility. Herein, amorphization Ni-cysteine coordination (aNi-cys) is constructed as efficient urea electro-oxidation reaction (UOR) catalyst with highly capable of suppressing competitive OER and promoting the Ni to Ni in-situ electrochemical configuration through deliberately regulating the Ni/l-cysteine coordination environment. The abundant ligand atoms (N, S, and O) of l-cysteine considerably tuned the Ni electronic structure to the most suitable state while the amorphization thin lamellas increased the exposed active sites and befitting for the access of electrolyte to electrode surface, resulting improved UOR activity with a large peak current density of 263 mA cm, far exceeding crystalline Ni-cysteine coordination (cNi-cys) and long-term stability for 50 h working.

Semi-Ionic F Modified N-Doped Porous Carbon Implanted with Ruthenium Nanoclusters toward Highly Efficient pH-Universal Hydrogen Generation.

Developing high electroactivity ruthenium (Ru)-based electrocatalysts for pH-universal hydrogen evolution reaction (HER) is challenging due to the strong bonding strengths of key Ru─H/Ru─OH intermediates and sluggish water dissociation rates on active Ru sites.

Achieving Negatively Charged Pt Single Atoms on Amorphous Ni(OH) Nanosheets with Promoted Hydrogen Absorption in Hydrogen Evolution.

Single-atom (SA) catalysts with nearly 100% atom utilization have been widely employed in electrolysis for decades, due to the outperforming catalytic activity and selectivity. However, most of the reported SA catalysts are fixed through the strong bonding between the dispersed single metallic atoms with nonmetallic atoms of the substrates, which greatly limits the controllable regulation of electrocatalytic activity of SA catalysts. In this work, Pt-Ni bonded Pt SA catalyst with adjustable electronic states was successfully constructed through a controllable electrochemical reduction on the coordination unsaturated amorphous Ni(OH) nanosheet arrays.
