2019年12月20日 · Herein we report a PtCu single atom alloy (SAA) catalyst with single Pt atom dispersed on Cu nanoclusters, which exhibits dramatically boosted catalytic performance (yield: 98.8%) towards...

2021年5月4日 · Herein, we report the synthesis of de-alloyed PtCu/C catalysts with high electrocatalytic performance and low Pt-loading, which can be prepared via a simple polyol method followed by an electrochemical de-alloying treatment for improving the ORR activity.

2011年10月18日 · Detailed STEM-EDX analyses further confirmed that Pt-Cu alloy exists as nanoparticles with a few nanometers in diameter and CuO with low crystallinity distributes on entire surface of the γ-Fe 2 O 3 support. The PROX activity showed different trends between high-Pt and high-Cu samples.

开始的时候能谱的缩写有很多，比如EDS，EDX，EDAX等，大家对此也都心照不宣，知道ED就是Energy Dispersive，后面因为X-ray Analysis和Spectrum这几个词的不同用法，导致了缩写的不同。

2021年3月1日 · PtCu alloy nanoframes are synthesised by a facile, scalable solvothermal strategy. The rhombohedral structure PtCu intermetallics (L 1 1 -PtCu) deliver only 15% attenuation after 30,000 potential cycles. In-situ heating experiment is conducted to observe the shape evolution during structural transformation.

2025年1月7日 · Coupled with simulated 4D-STEM data, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectrometry (EDX), and electron energy loss spectroscopy (EELS), this is a thorough study of the local structure–stability relationship of individual Pt–Cu nanoparticles.

2014年5月27日 · Cu@Pt–Ru core–shell supported electrocatalysts have been synthesized by a two-step process via a galvanic displacement reaction. XRD diffraction and EDX analysis, and cyclic voltammetry measurements revealed the presence of nanoparticles composed by a Cu-rich Pt–Cu core surrounded by a Pt-rich Pt–Ru shell.

Platinum deposited CuO nanostructure films were synthesized using the wet-chemical route and photochemical deposition methods. CuO nanostructure films were grown on copper foil as substrate via a...

In this work we have explored the experimental conditions to facilitate and enhance the insertion of Pt into the Cu 2−x Se nanocrystalline lattice, forming novel ternary phases that show a high degree of miscibility and compositional variability.

resultant carbon-supported CuNi@Pt-Cu core@shell nano-octahedra showed superior activity in electrochemical methanol oxidation reaction (MOR) compared with the commercial Pt/C catalysts and
