Zinc Oxide/ Titanium Oxide Core Shell Nanoparticles (ZnO/TiO2, 99.9%, APS: 80-100nm, Metal Oxide Core)

Zinc Oxide/ Titanium Oxide Core-Shell Nanoparticles

Applications

Environmental Remediation:

Photocatalytic Degradation of Pollutants: The combined photocatalytic properties of ZnO and TiO₂ make ZnO/TiO₂ core-shell nanoparticles highly effective in the degradation of organic pollutants, dyes, pesticides, and industrial waste in water and air. These nanoparticles can be used in water treatment plants, air purification systems, and environmental cleanup applications to remove toxic chemicals and harmful microorganisms.

Self-Cleaning Surfaces: Due to TiO₂’s ability to break down organic contaminants under UV light, ZnO/TiO₂ nanoparticles can be used to create self-cleaning surfaces in applications such as windows, tiles, building materials, and textiles. These surfaces degrade dirt and organic materials, reducing the need for frequent cleaning.

Energy Applications:

Solar Energy Harvesting: The ZnO/TiO₂ core-shell structure can enhance the performance of photovoltaic cells by improving the light absorption properties of the composite. TiO₂ can improve charge separation, while ZnO enhances charge transport and electron mobility. This makes ZnO/TiO₂ nanoparticles ideal for use in solar cells and photodetectors.

Solar-Driven Hydrogen Production: ZnO/TiO₂ nanoparticles are also explored for solar-driven water splitting for hydrogen generation. When exposed to solar light, the photocatalytic properties of the nanoparticles enable them to split water molecules into hydrogen and oxygen, a promising method for producing clean energy.

Biomedical Applications:

Antimicrobial and Antibacterial Agents: ZnO/TiO₂ nanoparticles are highly effective for antimicrobial applications, especially in wound healing and medical device coatings. The generation of reactive oxygen species (ROS) under UV light makes them effective against a wide range of bacteria, viruses, and fungi. These nanoparticles are also used in bandages, surgical tools, and catheters to prevent infections.

Photodynamic Therapy: The photocatalytic properties of ZnO/TiO₂ core-shell nanoparticles can be harnessed in photodynamic therapy (PDT), where light is used to activate the nanoparticles, generating ROS that can target and destroy cancer cells or bacteria. PDT is a promising treatment for localized infections or tumors.

Cosmetics and UV Protection:

ZnO/TiO₂ core-shell nanoparticles are widely used in cosmetic formulations such as sunscreens, where they provide effective UV protection. The TiO₂ shell blocks harmful UV radiation, while the ZnO core adds antioxidant and anti-inflammatory properties, making the composite ideal for skincare products.
