2020年4月1日 · Herein, we reveal such atomistic mechanisms of Cu 2 O growth during the oxidation process by real-time atomic imaging in an aberration-corrected environmental transmission electron microscope (AC-ETEM). We directly visualize the atomistic process of sequential bonding between Cu and O atoms onto the growing oxide surface.

2020年7月15日 · Cuprous oxide (Cu2O) nanoparticles are synthesized by aqueous precipitation method for the production of low-cost conductive ink, which is suitable for a printed, electronic application. The major drawback of copper ink, such as rapid oxidation overcomes by the formation of Cu2O ink.

2017年8月21日 · Using environmental transmission electron microscopy, here we report observations of the in-place formation of Cu 2 O/Cu interfaces via the oxidation of Cu, and subsequently probe the atomic...

2024年12月20日 · Graphitic carbon nitride (g-C 3 N 4), an emerging n-type two-dimensional semiconductor, has been identified as an ideal material for modifying Cu 2 O due to...

The high-resolution transmission electron microscope (HRTEM) image of CuO-Cu 2 O in Fig. 4b shows the presence of two different interplanar distances of 0.25 and 0.24 nm, corre- sponding to the...

X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FESEM), and high-resolution transmission electron microscopy (HRTEM) techniques were employed to characterize the samples. We elucidate the important parameters (including poly (vinyl pyrrolidone) (PVP) concentration, reaction time, and reaction temperature ...

2016年10月17日 · In this work, we report a facile method that involved a repeated double-potential pulse chronoamperometric (r-DPPC) deposition and a subsequent thermal oxidation to prepare the Cu 2 O/CuO...

2025年1月20日 · Cu2O作为一种本征p型半导体，具有~2.1 eV的直接带隙，因此被广泛用于可见光催化领域，但是其自身严重的光腐蚀和有限的二氧化碳捕获能力极大地制约了其在光电催化中的应用。 金属有机框架（MOFs）具有结构明确、大比表面积、结构可控等特点，将MOF整合到半导体中，构建Cu2O@MOF复合催化材料平台，不仅可以提高Cu2O材料的催化活性，并且可以提升Cu2O材料催化稳定性，但其光生电子空穴符合严重的问题仍旧无法得到有效解决，导致催化 …

In contrast, clear lattice fringe arrangements can be observed in the outer regions of the HRTEM images, indicating the crystalline features of the decorated Cu2O layer.

Cuprous oxide (Cu2O) is a highly efficient p-type semiconductor, which has an appropriate band gap and favorable energy band positions, making it ideal to be considered as a...
