  • 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

Application: 

Vanadium dioxide Nanoparticles is a good phase change material, which can be doped with tungsten to prepare intelligent photochromic film materials.

Vanadium dioxide Nanoparticles is a oxide near 68 ℃ with phase change. It can be imagined that if the nano VO2 powder material with the function of phase change is compounded into the base material and supplemented with other fillers, a composite intelligent temperature control coating based on nanom VO2 can be made. When the surface of the object is coated with this coating, when the internal temperature is low, infrared light can enter the interior; When the temperature rises to the critical phase transition temperature, the phase transition occurs. At this time, the infrared light transmittance decreases and the internal temperature gradually decreases.When the temperature drops to a certain temperature, the nano VO2 will undergo an inverse phase transition and the infrared light transmittance will increase, so as to realize intelligent temperature control.

Nano vanadium dioxide film and ultrafine powder can be widely used in electrical and optical switching devices, solar control materials, optical disc dielectric materials, coatings, thermistors and other fields due to their unique phase change characteristics.
