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
