ZIF‐Derived Co@Fe‐P Electrocatalyst With Core‐Shell Structure for Efficient Oxygen Evolution Reaction

Carbon Energy, EarlyView.
Fabrication of core‐shell Co@Fe‐P electrocatalyst for efficient oxygen evolution reaction. ABSTRACT Rational design of non‐noble electrocatalysts with high performance for oxygen evolution reaction (OER) still remains a challenge. In this study, a ZIF‐derived electrocatalyst (Co@Fe‐P) with a core‐shell structure is designed by using Co‐compounds as the

A picogram and nanometer scale photonic crystal opto-mechanical cavity [PDF]

, 2008
We describe the design, fabrication, and measurement of a cavity opto-mechanical system consisting of two nanobeams of silicon nitride in the near-field of each other, forming a so-called "zipper" cavity.

A “Two‐Pronged” Strategy Boosting the Activity and Stability of Nickel–Iron Catalysts Toward Anion Exchange Membrane Water Electrolysis

Carbon Energy, EarlyView.
A “two‐pronged” strategy has been developed to construct a substrate‐strengthened, organophosphorus‐protected nickel‐iron electrode for efficient and robust OER electrocatalysis. Owing to the reinforced catalyst–substrate interaction and minimized active site loss by organophosphorus protection, the integrated electrode serves as an robust and ...

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.

Enhancing the d–Electrocatalytic Activity of MXene Through Defect Engineering

Carbon Energy, EarlyView.
Applications of MXene. ABSTRACT Due to their versatile and tunable surface and bulk chemistry, MXenes have great potential as electrocatalysts for batteries and supercapacitors. When compared with other electrocatalytic processes, in electrocatalytic reactions, MXenes could improve ion diffusion and charge transfer by either providing functional groups
