Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Research progress in hot deformation behavior of high entropy alloys

Cailiao gongcheng
The high entropy alloy overturns the traditional design idea that one or two elements are the main elements, and its design concept of multi-element and high mixing entropy endows it with excellent properties such as high strength, high toughness ...
