Results show that a ternary CuO/Cu2O/Cu composite was obtained when a single Cu-MOF was calcined in air. The Cu and Cu2O in the product decreased as the melamine in the raw material increased....

2014年8月29日 · Single crystal copper oxide nanoplatelets with a high percentage of {001} facets were synthesized by a facile hydrothermal approach. The as-prepared materials were characterized by X-ray...

2013年12月18日 · Reduction of CuO nanowires results in the formation of a unique hierarchical hybrid nanostructure, in which the parent oxide phase (CuO) works as the skeleton while the lower oxide (Cu 2 O) resulting from the reduction reaction forms as partially embedded nanoparticles that decorate the skeleton of the parent oxide.

2021年2月4日 · In this contribution, we report on a new family of free-standing 2-dimensional Cu (II) oxide electrocatalysts for the CO2RR under neutral pH conditions. Owing to their 2D nature, Cu (II)O...

2023年3月27日 · 日前， 北京科技大学数理学院的王荣明教授和刘焕明教授课题组在 Rare Metals 上发表了题为“ Synthesis of FeOOH scaly hollow tubes based on Cu2O wire templates toward high-efficiency oxygen evolution reaction”的研究文章，利用Cu2O线作为模板制备出FeOOH纳米鳞片组成的微纳米中空管并以其 ...

2024年12月22日 · The CuO/Cu 2 O crystallizes as a porous structure with various small particles. Furthermore, the selected area electron diffraction (SAED) arrangement shown in the inset of Figure 2a consists of clearly defined concentric circles that indicate the sample's polycrystallinity.

... selected area electron diffraction (SAED) pattern (Fig. 5a) shows the number of rings which signifies the very small size of grains and polycrystalline nature of the Cu 2 O nanoparticles....

These copper oxide phases were identified by selected-area electron dif- fraction (SAED) and a nanobeam diffraction technique using an FEI Titan 80-300 Cubed TEM. The presence of cubic-phase Cu...

2008年10月1日 · 摘要 在环境条件下，不使用任何表面活性剂，通过γ-辐照还原反应合成了具有凹面的单晶微米级Cu2O立方体。 选区电子衍射 (SAED) 研究表明这些立方体是单晶。

2022年9月1日 · Benefiting from high electrical conductivity, plentiful active sites, high intrinsic activity per active site, and fast rate for ionic and electronic transfer, these disorders nanoneedles structured S-Cu2 O-CuO demonstrate outstanding OER performance needing an overpotential of 450 mV to attain a high geometric activity (1000 mA cm −2) in 1 M KOH.
