Zinc/ Zinc Oxide Core Shell Nanoparticles (Zn/ ZnO, 99.9%, APS: 80-100nm)

Zinc/ Zinc Oxide Core-Shell Nanoparticles

Zinc/zinc Oxide Core-Shell Nanoparticles are a unique class of core-shell nano materials where the core consists of zinc (Zn) and the shell is made of zinc oxide. These nanoparticles combine the beneficial properties of both ZnO making them versatile for a wide range of applications in areas like electronics, photocatalysis, sensing, and biomedicine.

Structure and Composition:

Core: Zn/ZnO

Zinc/zinc Oxide Core-Shell Nanoparticles is a widely used metal known for its conductivity, biocompatibility, and low toxicity. In the core-shell structure, the Zn core provides electronic properties that are important for charge transport and photoelectric applications.

Zinc itself is highly reactive in certain conditions and is prone to oxidation when exposed to air, which is why the Zinc shell plays a crucial role in enhancing the durability and chemical stability of the nanoparticles.

Shell:

Zinc/zinc Oxide Core-Shell Nanoparticles is a wide-bandgap semiconductor (≈ 3.3 eV) with numerous advantageous properties, including photocatalytic activity, antibacterial properties, high thermal stability, and UV absorption. When used as a shell material, imparts these beneficial features to the nanoparticles, enhancing their surface reactivity, photostability, and chemical resilience.

The Zinc shell also acts as a protective barrier for the Zn core, preventing oxidation and preserving the electrical properties of the core while providing functionalization sites for further modifications.

Properties:

The Zinc/zinc Oxide Core-Shell Nanoparticles imparts a combination of metallic and semiconducting properties, offering unique characteristics that can be fine-tuned for specific applications:

Photocatalytic Properties:

The Zinc shell exhibits photocatalytic activity, particularly under UV light, due to its wide bandgap and the ability to generate electron-hole pairs. This makes zinc core-shell nanoparticles ideal for applications such as water purification, air treatment, and solar energy conversion.
