Rare Metals, EarlyView.ABSTRACT Precise control of chemical ordering in bimetallic nanocatalysts offers a route to decouple activity and selectivity in acetylene hydrogenation, but direct atomic‐scale evidence linking surface order to catalytic performance is scarce. Here, we tune Pd‐Cu nanoalloys from chemically disordered to highly ordered states by composition control and

Rare Metals, EarlyView.ABSTRACT As a core component in the electrochemical water splitting system, the cathode catalyst is capable of boosting the kinetics of the hydrogen evolution reaction (HER), while the scarcity and expenditure of current noble metal‐based electrocatalysts seriously restrict the large‐scale commercial development of hydrogen manufacturing devices. Here,

符合独立五元环规则的C100（417）Cl28形成机理的密度泛函理论研究 [PDF]
, 2018 实验上捕获到C100（417）Cl28,但其形成机理仍不清楚。本文采用密度泛函理论（DFT）方法研究了生成C100（417）Cl28的反应机理,考虑了可能的经Stone-Wales（SW）转化、直接氯化和来自于骨架转变等反应路径。结果表明:C100（417）Cl28形成的最主要来源是通过C102（603）骨架转变,即经历氯化、C2失去和SW转变而来。该结果能很好解释实验结果,对富勒烯氯化物的合成提供了理论依据。国家自然科学基金(21573182)资助项目~

Rare Metals, EarlyView.ABSTRACT Photocatalytic hydrogen production from water splitting is a promising strategy for sustainable and clean energy generation. However, the design of low‐cost, highly active photocatalysts remains a critical challenge. In this study, covalent organic frameworks (COFs) were loaded onto the surface of Cd0.9Cu0.1S to fabricate COF/Cd0.9Cu0.1S ...

Rare Metals, EarlyView.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser
