  • Platinum Black Catalyst Platinum Nanopowders

    Customized Metal Platinum Black Catalyst Platinum Nanopowders Platinum is one of noble metals, it is one of the best catalyst and antioxidants, nano platinum ( Pt ) with small particles size, strong, safe, stable, reliable, environmentally friendly, non-toxic, tasteless, harmless, can be widely used in biomedical, Catalytic industry, cosmetic etc. 1. Platinum Nanopowders for biomedical  Hydrogen and nano-platinum have a synergistic effect that can be used in conjunction with the treatment of oxidant stress disorders; Studies have shown that platinum nano particle-mediated photo-thermal effect in the treatment of bone metastases in nude mice can be a good inhibition of bone tumor growth and osteolytic bone destruction; Lactic acid bio-sensor based on nano - platinum black modification for rapid detection, etc.  2. Platinum Nanopowders as catalyst  Nano platinum are widely applied in catalyst part, Nano-platinum powder has excellent bio-catalytic activity, it can be applied to polymer hydrogenation, reduction and synthesis. Nano platinum also can be used as fuel cell catalyst, due to its high cost, due to its high cost, now some use nano nickle to replace the platinum, and some are looking for ways to improve nano platinum efficiency as catalyst in fuel cells to save cost. Last year Chinese researches have developed a superfine platinum nanowire catalyst on the surface of the zigzag, greatly increasing the surface activity and specific surface area of the fuel cell catalyst, increasing its overall catalytic activity by more than 50 times. 3. Platinum Nanopowders for cosmetics Platinum nanoparticles , due to its strong oxidation resistance Platinum can effectively remove free radicals in the human body. Play the anti-aging effect and at the same time to achieve whitening bright. Platinum Nanopowders can also be used for food preservative, car exhaust purification, etc. Nano platinum do have a lot of amazing functions, we cannot list its amazing functions one by one though.  If you're interstsed in Platinum Nanopowders, please feel free to contact us as hwnano@xuzhounano.com. more

      Nano Colloidal Silver particles directly into the bacteria and the oxygen metabolism enzyme (-SH) binding, the unique mechanism of action of the bacteria suffocation and death, can kill most of the bacteria, fungi, molds, spores and other microorganisms in contact with it. The eight authoritative institutions in China have found that they have comprehensive antibacterial activity against drug-resistant pathogens such as E. coli, Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus pyogenes, Enterococcus faecalis, and anaerobes. Common bacteria such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and other G+ and G-borne pathogens on the surfaces of burns and wounds have bactericidal action; Chlamydia trachomatis, causing sexually transmitted diseases Neisseria gonorrhoeae also has a strong bactericidal effect.

      One antibiotic kills about six pathogens, while nanosilver kills hundreds of pathogenic microorganisms. Kill bacteria, fungi, trichomoniasis, trichoderma, chlamydia, gonococci, strong bactericidal effect, have the same killing effect on antibiotic resistant bacteria!

Photochromic material Ag/TiO2 nanoparticles
Photochromic material Ag/TiO2 nanoparticles

      Titanium dioxide material can selectively etch metal nanoparticles through electron transfer with metal Ag nanoparticles in the excited state, and change the optical absorption characteristics of the material, thus the Ag/Tio2 nanomaterials can change color under the light excitation of different wavelengths.       Experimental demonstration: 1) 500 ℃ heat treatment was carried out on the TIO2 thin film,it is helpful for photocatalytic deposition of Ag particles, and Ag/TIO2 thin film has the obvious photochromic phenomenon; 2) as the content increase of Ag particles deposited on TIO2 films, the photochromic rate of Ag/TIO2 films increases correspondingly, but the reaction rate of photochromic reaction is inhibited when the content of Ag particles exceeds a certain amount.       If you're interested in the material, please not hesitate to contact us , and we will make a tailor for matching your products.

Fe2O3 Iron(III) oxide, ferric oxide nano particles for sale

Fe2O3 Iron(III) oxide, ferric oxide nano particles for sale Iron(III) oxide, also named for ferric oxide, is the inorganic compound with the formula Fe2O3.  particle size 20-30nm, purity 99.8%, Price competitive especially in bulk       When the size of the Fe2O3 Iron(III) oxide is small to nanometer(1~100nm), the surface atomic number, specific surface area and surface energy of the iron oxide particles increase sharply with the decrease of the particle size, which shows the features of small size effect, quantum size effect, surface effect and macroscopic quantum tunneling effect. It has good optical properties, magnetic properties and catalytic properties etc, which has wide application in the fields of light absorption, medicine, magnetic media and catalysis.       Fe2O3 Iron(III) oxide is widely used as pigments and coatings, magnetic materials and magnetic recording materials, catalysts, sensitive materials etc. With the improvement of people's living standards, people pay more and more attention to medicine, cosmetics, food colorants used. Non-toxic colorant has become the focus of attention. Under the condition of strictly controlling the arsenic and metal content of nano-iron oxide, it is a good colorant. Ferric oxide nano particles can be used in the manufacture of cosmetic powder, if the used with pearl color, it can make the pearl pigment colored and add the charm of pearl powder. The transparent iron oxide is also used in medicinal gelatin capsules, jellies and certain beverages as a coloring agent.       In the application of light absorbing materials: the quantum size effect of the nanoparticles has a blue shift to the absorption of light at a certain wavelength and a broadening of the absorption band for light of various wavelengths. The UV absorption material of nanoparticles is created by use of these two characteristics.In general, the nanoparticle UV absorbing material is a film formed by dispersing the microparticles into a resin. The ability of this film to absorb ultraviolet light depends on the size of the nanoparticles and the amount and composition of the nanoparticles in the resin. Fe2O3 nano-particles of poly-resin film on the light below 600nm have a good absorption capacity, which can be used as semiconductor devices, ultraviolet filters.       Fe2O3 Iron(III) oxide with its excellent performance and wide range of uses has attracted people's attention. Its applications are fruitful in field of food, medicine, decorative materials, and ceramics. With the deepening of researches, new properties of nano iron oxide and its applications will also be increasing. There is no doubt that the application prospect of nanometer iron oxide will be very broad. by Jemma
