Tailoring Intermediate Adsorption Through d‐band Mismatch Strategy of Heterojunction to Achieve Industrial Overall Water Splitting

Advanced Science, EarlyView.
This paper demonstrates the fabrication of a Ni3Mo/Ni3N junction to investigate d‐band engineering and elucidate the specific roles of Ni3Mo and Ni3N active sites in improving catalytic activity. Through integrated spectroscopic characterization and first‐principles modeling, for the first time, a d‐band mismatch mechanism has been proposed to ...

Hydroxyl Self‐Trapping Strategy Enables Electrocatalysis at Ampere‐Level Current Densities: Kinetics‐Driven Lattice Oxygen Activation for Cl−‐Rich Alkaline Water Electrooxidation

Carbon Energy, EarlyView.
This study designs a CrOx‐engineered Ni‐based catalyst enabling efficient and stable seawater electrolysis. The catalyst utilizes a dynamic interfacial barrier that selectively adsorbs OH− to repel Cl− corrosion while activating lattice oxygen‐mediated pathways.

Hydroprocessing of synthetic kerosene over a non‐sulphided Ni/Al2O3 catalyst: Impact of alcohols and ketones on alkene conversion

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...
