In essence, nano copper oxide refers to copper (II) oxide particles that are engineered at the nanoscale, which typically range between 1 and 100 nanometers. At this scale, materials often exhibit different physical, chemical, and optical properties as compared to their bulk counterparts. For copper oxide, this means enhanced conductivity, higher surface area, increased reactivity, and improved antimicrobial effects.
The nanoparticles typically appear as black or brownish powders. They are synthesized using methods such as sol-gel processing, thermal decomposition, hydrothermal synthesis, and green synthesis using plant extracts. That way, researchers and manufacturers can control particle size, morphology, and purity. These characteristics are crucial factors that determine the performance of nano copper oxide in different applications.
The nano copper oxide market is poised to register robust growth in the coming years. The market was valued at USD 360.56 million in 2024. It is projected to grow to USD 838.85 million by 2034, registering a CAGR of 8.8% during 2025–2034.
Nano copper oxide exhibits a range of unique properties that make it applicable across various sectors. Here’s a deeper look into these properties:
High Surface Area-to-Volume Ratio
At the nanoscale, copper oxide particles have a significantly increased surface area compared to their volume. The high surface area allows more atoms or molecules to be exposed and interact with their surroundings. This makes the material more reactive and efficient in surface-driven processes.
Enhanced Electrical Conductivity
Copper is known for its excellent electrical conductivity. This property is often retained and improved at the nanoscale. Nano copper oxide can be used in printed circuits, conductive coatings, and microelectronic components owing to its ability to efficiently transfer electric charge.
Semiconducting Behavior
Nano copper oxide is a p-type semiconductor, which means it has more holes as compared to electrons. This makes it suitable for various semiconductor applications such as gas sensors, thin film solar cells, and optoelectronic devices. The narrow bandgap of nano copper oxide enables it to absorb and respond to a wide range of wavelengths.
Thermal and Chemical Stability
Nano copper oxide is relatively stable at high temperatures and can withstand chemical environments. These properties are crucial for industrial catalytic reactions, sensor fabrication, and battery manufacturing. Their ability to maintain structural integrity under these conditions makes them a reliable choice for high-performance materials.
Strong Antimicrobial Activity
Another key feature of nano copper oxide is its broad-spectrum antimicrobial effectiveness. These nanoparticles can disrupt microbial cell membranes, generate reactive oxygen species (ROS), and interfere with protein functions, ultimately killing or neutralizing harmful bacteria, fungi, and even viruses.
Here’s a look at some of the most common applications of nano copper oxide:
