2021年4月25日 · Self-activation-induced ZnO encapsulation of copper nanoparticles is first discovered. The optimal Cu + /Cu 0 ratio allows a remarkable improvement of the MSR activity. Cu 2O/ZnO synergistic sites significantly reduce the activation energy barrier of the rate-determining step.

2015年1月20日 · The optimized Cu2O/ZnO NRs array p-n heterostructures exhibited enhanced PEC performance, such as elevated photocurrent and photoconversion efficiency, as well as excellent sensing performance...

2014年1月1日 · In this work we report a novel two step electrochemical deposition method for the synthesis of ZnO/Cu 2 O heterojunctions. It is a simple, low-cost, non-toxic and -relative to the existing methods- low temperature fabrication procedure [11, 12]. In addition it can be easily scaled up and has a low energy footprint.

2023年5月31日 · Nanostructured Cu2O/ZnO heterojunction solar cell was fabricated by the electrodeposition of Cu2O into the ordered ZnO cavity-like nanopatterns. The formation of intercrossed interface between Cu2O and ZnO could increase the p-n heterojunction area effectively compared to the planar structure.

2023年3月1日 · Indium tin oxide, semiconductor nanomaterial ZnO, and Cu2O were first loaded on the surface of the optical fiber to form an optical fiber probe. Large-volume macroscopic spatial light is replaced by an optical fiber path, and remote light injection is implemented.

Vertically aligned Cu2O/ZnO hetero-nanorod arrays were synthesized on indium-doped tin oxide (ITO) glass substrates using a simple hydrothermal method followed by an electrodeposition process. Scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM) results show that Cu

2023年1月1日 · In order to improve the photocatalytic performance and deeply analyze the photocatalytic mechanism, the Cu2O nanocrystals with cubic, cuboctahedral and octahedral structures were combined with n-type ZnO to prepare Cu2O/ZnO heterojunction photocatalysts.

2023年2月21日 · Herein, an emerging Z-scheme photocatalyst composed of ZnO single crystal nanorods (SCNRs) assisted Cu 2 O ultrafine nanoparticles (Cu 2 O-UNPs) is successfully synthesized using a hydrothermal method in conjunction with a chemical reduction. The two parts of this heterostructure are chemically bonded one another to form a tight interface.

2018年3月12日 · This Cu@Cu 2 O/ZnO nanostructure exhibited significantly enhanced stability than that of regular Cu@Cu 2 O, which accounted for the remarkably enhanced photocatalytic H 2 evolution rate through water splitting, relative to pristine ZnO nanorods, over an extended wavelength range due to the plasmonic Cu core.

Zinc oxide (ZnO) nanorods are grown hierarchically on cuprous oxide (Cu2O) nanoneedles to form a Cu2O/ZnO hetero-nanobrush assembly. This increases the overall aspect ratio, which helps to enhance the field emission properties of the system.
