  • 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

carbon nanotubes(CNTs)
carbon nanotubes(CNTs) for resisting chemical and biological weapons

      Scientists using carbon nanotubes(CNTs) and polymer film to develop new fabrics: can resist chemical and biological weapons       Scientists from Lawrence Livermore National Laboratory used carbon nanotubes and flexible polymer film to make synthesis of a breathable, lightweight fabric, wihch could help soldiers against the chemical and biological weapons.  A unique channel created by Carbon Nanotubes has achieved a good air permeability. Meanwhile, the density of the fabric, of which was only 5 nm pore diameter was quite high. It is understood that biological weaponsa such as viruses, usually it's bigger than 10 nm in size. In the experiment, the scientists confirmed that the new material is with the ability to repel dengue virus.  At the same time, to make the research results protects against chemical weapons also, scientists used some chemical-sensitive materials to improve carbon nanotubes, and ultimately achieved the goal.       Here sells purest and cheapest Carbon Nanotubes in the world. Carbon nanotubes is available with different purity grades and surface functionalization. Carbon Nanotubes is produced by Chemical Vapor Deposition (CVD) method by HW NANO and depending on the diameter one can obtain either single-walled Carbon Nanotubes(SWCNTs) ,double-walled carbon nanotubes (DWCNTs)or multi-walled Carbon Nanotubes (MWCNTs). Our current capacity for the production of MWCNTs far exceeds that of other suppliers.   Spec of carbon nanotubes:   1) SWCNT: diameter: 2nm, Length: short tube 1-2um and long tube 5-20um, purity: >91%,95%,99%   2) DWCNT: diameter: 2-5nm, Length: short tube 1-2um and long tube 5-20um, purity: >91%,95%,99%   3) MWCNT: diameter: 8-20nm,30-60nm,60-100nm, Length: short tube 1-2um and long tube 5-20um, purity: >99%   4) Low purity for the three ones above are all available.   5) Functionalized carbon nanotubes: COOH-CNTs, OH-CNTs, Amino-CNTs, Metal coated CNTs...   6) Dispersion: CNTs water dispersion, and CNTs oil dispersion.
