Copper Oxide Nanoparticles

Updated: 2026-07-15

Overview

Copper oxide nanoparticles (CuO NPs) are nanoscale particles of copper oxide, typically ranging from 1 to 100 nanometers in size. Their small size and high surface area-to-volume ratio impart unique physical, chemical, and biological properties. CuO NPs are synthesized through various methods, including chemical precipitation, sol-gel, and hydrothermal processes. These nanoparticles are valued for their antimicrobial, catalytic, and semiconducting properties, making them versatile in industrial and scientific applications. Due to their nanoscale dimensions, CuO NPs exhibit quantum effects and enhanced reactivity compared to bulk copper oxide. This has led to their widespread use in fields such as electronics, energy storage, and environmental remediation. The ability to functionalize their surface further expands their utility in specialized applications.

Physical and Chemical Properties

Copper oxide nanoparticles are characterized by their black or brown powder form, with a density of 6.31 g/cm³ and a high melting point of 1,326°C. They are insoluble in water but soluble in acids and ammonia, which allows for easy integration into various chemical processes. Their nanoscale size results in a large surface area, enhancing their reactivity and making them effective catalysts. The semiconducting properties of CuO NPs, with a bandgap of approximately 1.2 eV, make them suitable for electronic and optoelectronic applications. Additionally, their antimicrobial activity is attributed to the release of copper ions, which disrupt microbial cell membranes. These properties are highly dependent on particle size, shape, and surface chemistry, which can be tailored during synthesis.

Main Applications

CuO NPs are widely used in catalysis, where they serve as efficient catalysts for oxidation and reduction reactions. Their high surface area and reactivity make them ideal for environmental applications, such as the degradation of pollutants. In electronics, they are employed in sensors, transistors, and photovoltaic devices due to their semiconducting properties. The antimicrobial properties of CuO NPs are leveraged in coatings for medical devices, textiles, and packaging materials to prevent microbial growth. They are also explored for use in energy storage systems, such as batteries and supercapacitors, owing to their electrochemical activity. The versatility of CuO NPs continues to drive research into new applications, including drug delivery and cancer therapy.

Safety and Storage

Handling copper oxide nanoparticles requires caution due to potential health risks associated with inhalation or skin contact. Exposure can lead to respiratory irritation and other adverse effects. Proper personal protective equipment (PPE), including gloves, masks, and lab coats, should be used when working with CuO NPs. Adequate ventilation and engineering controls are essential to minimize airborne particles. Storage conditions should ensure the nanoparticles remain dry and stable, away from moisture and incompatible substances. Containers should be tightly sealed and labeled clearly. Disposal must comply with local regulations to prevent environmental contamination. Safety data sheets (SDS) provided by manufacturers should be consulted for specific handling and storage guidelines.

B2B Procurement Guide

When procuring copper oxide nanoparticles, B2B buyers should prioritize suppliers with a proven track record in nanoparticle production. Key factors to consider include particle size distribution, purity (typically 99% or higher), and surface functionalization, which can impact performance in specific applications. Certificates of analysis (CoA) should be requested to verify these parameters. Pricing varies based on quantity, purity, and particle size, with bulk purchases often offering cost advantages. Buyers should also evaluate the supplier's ability to provide customized solutions, such as tailored surface coatings or dispersions. Reliable suppliers will offer technical support and documentation to ensure safe and effective use of CuO NPs in industrial processes.
