2019年11月4日 · Here, by using correlated scanning fluorescence X-ray microscopy and environmental transmission electron microscopy at atmospheric pressure, in operando, we directly observe that the (110) facet of...

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.

2018年7月2日 · Here, using surface photovoltage microscopy, we demonstrate that the photogenerated charges can be separated effectively in a high-symmetry Cu 2 O photocatalyst particle by asymmetric light...

2019年2月1日 · UV–vis absorption spectra exhibit peaks with characteristic wavelengths of Cu 2 O. SEM and TEM reveal particles with a cubic morphology at 15 mM CuCl 2, with an average particle size of 100 nm. Cu 2 O particles are also grown in an octahedral shape at 16 mM of CuCl 2, having an average particle size of 150 nm. Finally, truncated octahedral ...

2018年4月30日 · Here we developed an easy and environment friendly synthesis protocol for nanoparticles of both types of copper oxide and investigated in detail their structural, optical and electronic property. Synthesized materials were characterized using X-ray diffraction, SEM, TEM, FTIR-spectroscopy and UV–Vis reflectance measurements.

2020年7月13日 · Here, using liquid cell transmission electron microscopy, we show the formation of cubic copper oxide particles from copper sulfate solutions during direct electrochemical synthesis and their...

Cu 2 O microcrystals with well-formed facets were synthesized by a simple hydrothermal method. The surface stabilities and photocatalytic properties of Cu 2 O microcrystals were systematically investigated. Cu 2 O {100} and {110} facets gradually disappear and transform into nanosheets during the photodegradation of methyl orange (MO) dye.

2025年1月21日 · Synthesis of rhombic-dodecahedral Cu2O particles on a quantitatively relevant scale has been achieved. The goal of the work was understanding the effect of each step of the synthesis process with the aim of being able to drive it.

2017年6月26日 · Scavenger results suggest that photogenerated electrons and holes experience a large barrier at the {100} faces of cubes preventing charge migration to the particle surfaces, leading to the photocatalytic inactivity of Cu 2 O cubes.

2016年11月28日 · Single Cu 2 O superstructure particle exhibits an outstanding surface-enhanced Raman spectroscopy performance with the limit of detection as low as 10 −9 mol L −1 and metal comparable enhancement factor (8 × 10 5) due to the synergetic effect of vacancies defect-facilitated charge-transfer process and copper vacancies defect-induced ...
