Product Overview 

Cerium (Ce) is one of the most abundant and cheap rare earth elements. Due to its unique 4f electronic structure, CE has been widely used in many fields such as alloy, fluorescence, magnetism and catalysis in recent years. Accordingly, its cerium oxide (light yellow powder) has also attracted great attention. The CeO2 crystal structure is cubic fluorite structure, in which the metal cation (Ce4+) is arranged according to the face-centered cubic lattice, while the anion (O2-) is located in the tetrahedron center. Ce elements usually contain two oxidation states, Ce4+ and Ce3+. When the temperature is very high or in a reducing environment, it can be reduced to CeO2-x (0<x¡ãC.5), resulting in the two valence states can be quickly and reversibly converted to each other, so oxygen vacancy defects are very easy to appear in the lattice of CeO2-x. Due to their inherent oxide defects and excellent REDOX properties and oxygen storage capacity, CeO2 nanoparticles are commonly used as heterogeneous catalysts or active oxide carriers of catalysts.

Mesoporous Ceria Nanoparticles (CeO¡ãCNPs) are nanomaterials with mesoporous structures with pore sizes between 2 and 6 nm. The mesoporous structure provides a large specific surface area and more active sites for various reactions.

Product Features

Mesoporous structure: mesoporous pores can not only be used as a material transport channel to promote the diffusion and release of drugs, catalysts or other active substances, but also improve the specific surface area of the material.

High specific surface area: Due to the presence of mesoporous structure, mesoporous cerium dioxide nanoparticles usually have a very high specific surface area, which helps to increase the contact area with the reactants, improve catalytic efficiency or drug loading.

Chemical stability: Cerium dioxide itself is a chemically stable material that can maintain its structure and properties under a variety of environmental conditions.

Biocompatibility: In the field of biomedicine, mesoporous cerium dioxide nanoparticles show good biocompatibility and are suitable for use as drug carriers.

Application Fields

In the field of catalysis: mesoporous cerium dioxide nanoparticles have a wide range of applications in the field of catalysis, such as catalytic reduction of nitrobenzene compounds, automotive exhaust purification. Its high specific surface area and mesoporous structure enable the catalytic reaction to be carried out efficiently on the surface of nanoparticles.

Biomedical field: As a drug carrier or bioimaging agent, mesoporous cerium dioxide nanoparticles also show great potential in the biomedical field. Its good biocompatibility and easy surface functionalization enable the drug to be more efficiently encapsulated and released to the target location.

Energy field: In energy storage and conversion equipment such as fuel cells and lithium-ion batteries, mesoporous cerium dioxide nanoparticles can also be used as electrode materials to improve the energy density and cycle stability of the equipment.

Environmental protection field: Using the catalytic performance of mesoporous cerium dioxide nanoparticles, it can be applied to environmental protection fields such as wastewater treatment and air purification to effectively remove harmful substances and improve environmental quality.

Sprayer breaks, but concept is great. Get different one.
Great and useful idea, but spray isn’t good. Even when it worked it didn’t release enough fluid, and it jammed and broke within two days. Luckily I swapped the spray head for one from another product, so I can still use the stand as it should have worked. Get a different kind, and you will love it if it works.

Sprayer gets stuck
Color: Black
It’s perfect having the spray bottle in the paper towel holder butttt the sprayer gets stuck already and it’s only been a month so I can’t constantly spray in one motion, sometimes you have to do fix it yourself bc it won’t pop back up on its own

Handy
Color: Black
This is such a neat piece for your kitchen. Of course it is convenient for paper towels but the added feature of having a spray bottle included is very convenient to keep your counters sparkling. I put in the stone polish and sealer. You could put windex for stove and fridge or water cleaner you wish. I highly recommend this and it is very affordable!

Waste of money 😒 not happy with this purchase at all
Color: Black
Ughhhh u get wat u pay for 😒 the spray bottle doesn’t click in and out it just sits there looking at u they had a foam down in the tube so I thought it was some type of cushion so u can push it down and it springs back up 🤔nope I took the cushion out and the bottle sank to the bottom of the darn tube 😵‍💫 been wanting one of these for a long time this just a lemon 🍋 for me Imma send it back I try a different brand see wat happens 🥹
