2024年2月10日 · These Au-steered undercoordinated Cu sites facilitate CO binding, enabling selective electroreduction of CO into n-propanol with a high Faradaic efficiency of 48% in a flow cell. This work provides new insight into the regulation of the oxide-derived catalysts reconstruction with a secondary metal component.

2017年12月20日 · Here, graphene-coated Cu is employed to investigate the facet-dependent anticorrosion of metals. It is demonstrated that as-grown graphene can protect Cu(111) surface from oxidation in humid air lasting for more than 2.5 years, in sharp contrast with the accelerated oxidation of graphene-coated Cu(100) surface.

Copper is a chemical element. It has the symbol Cu (from Latin cuprum), and the atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color.

2025年2月3日 · Here we propose an innovative two-step synthesis strategy for preparing high-efficiency nanocrystalline Cu electrocatalysts with abundant distorted nanotwins (DNTs). We start by producing cuprous...

The University of Colorado Boulder (CU Boulder, [9] CU, or Colorado) is a public research university in Boulder, Colorado, United States. Founded in 1876, five months before Colorado became a state, it is the flagship university of the University of Colorado system.

銅 （英語： Copper），是最早發現的 化學元素， 化學符號 为 Cu （源于 拉丁語： Cuprum[3]）， 原子序數 为29， 原子量 為 63.546 u。 純銅是柔軟的 金屬，表面剛切開時為紅橙色帶金屬光澤、 延展性 好、 導熱性 和 導電性 高，因此在 電纜 、 電氣 和 電子元件 是最常用的材料，也可用作建築材料，以及組成眾多種 合金，例如用於珠寶的 紋銀，用於製作船用五金和硬幣的 白銅 以及用於 應變片 和 熱電偶 的 康銅。 銅合金 機械性能優異， 電阻率 很低，其中最重 …

5 天之前 · In this work, we demonstrate a facile synthetic strategy for Cu SACs utilizing the nano-constrained environment of TOK. Cu precursors were introduced into the nano-constrained environment by milling, followed by calcination to facilitate the formation of Cu SAC through anchoring to the Si-OH within the silica wall.

2025年2月1日 · Among the catalysts studied for electrocatalytic CO 2 RR, Cu-based catalysts show the best catalytic performance for multicarbon products and are thus regarded as the most promising class of catalysts for CO 2 catalysis.

2024年11月14日 · Annealing can significantly reduce the residual stress of nanotwinned Cu, which has been attributed to the decrease in the geometric necessity dislocation density. 110-oriented nanotwinned Cu had drastic recrystallization, while 111-oriented nanotwinned Cu and non-oriented nanotwinned Cu had only slight recrystallization.

2024年5月1日 · Copper nanoparticles such Cu(PO 4) 2, CuS, CuI, CuO, CuCO 3, and Cu 2 O are anti-cancer (Laha et al., 2014, Laha et al., 2012). Each copper-based nanoparticle has distinct characteristics and uses. Despite little investigation, Cu(PO 4) 2 nanoparticles may be useful in catalysis, luminescence, and ion exchange (Naciri et al., 2019).
