Zirconium coated Carbon Nanotubes (Zr/CNT)

Zirconium coated Carbon Nanotubes– CNTs decorated with metal nanoparticles (NPs) like Silver nanoparticles, Gold nanoparticles, Nickel nanoparticles, copper nanoparticles, Magnesium nanoparticles, palladium nanoparticles, platinum nanoparticles, exhibit outstanding chemical activity due to their large active surface area and unique crystallographic surface structure.

Zirconium coated Carbon Nanotubes– Carbon nanotubes can be decorated with indirect and direct physicochemical and physical methods mainly with noble and transition metals. The fabricated nanocomposites possess a series of advantageous applications in the fields of fuel cells, solar cells, catalysis, drug delivery, chemo/biosensors, and hydrogen storage.

Applications

Catalysis and Chemical Reactions

Catalyst Supports: Zr-CNTs are explored as catalyst supports in a variety of chemical processes, including hydrogenation, dehydrogenation, oxidation, and reduction reactions. The high surface area of CNTs combined with the catalytic properties of zirconium makes them effective for improving the efficiency and selectivity of catalytic reactions. Zr-CNTs are particularly promising in processes such as carbon-carbon coupling reactions and hydrogen production.

Electrocatalysis: Zr-CNTs are being studied as electrocatalysts in energy conversion devices such as fuel cells and batteries. The high conductivity of CNTs and the catalytic properties of zirconium could make Zr-CNTs effective in improving the performance of electrochemical reactions such as oxygen reduction and hydrogen evolution.

 Energy Storage and Conversion

Supercapacitors: Zr-CNTs can be used in the development of supercapacitors, which are energy storage devices that offer high power density and rapid charge/discharge cycles. The combination of CNTs’ high surface area and zirconium’s stability and conductivity can enhance the performance of supercapacitors, particularly in high-energy applications such as electric vehicles and portable electronics.

Batteries: Zr-CNTs are also being explored for use in batteries, including lithium-ion and sodium-ion batteries. The titanium-coated CNTs provide enhanced electrical conductivity and mechanical strength, improving battery performance, capacity, and stability over time.

Hydrogen Storage: Due to the high hydrogen absorption capacity of zirconium, Zr-CNTs are being studied for use in hydrogen storage applications. The CNTs offer a high surface area for hydrogen absorption, while the zirconium coating can enhance hydrogen uptake and storage capacity, making the material suitable for use in fuel cell technology and clean energy applications.
