  • 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 more

About a greener recipe -------copper nanowires

Indium tin oxide (ITO) is the most widely used transparent conductor in today’s consumer technology, featuring in solar cells, touch screens and LED displays.

However, alternatives are being sought due to the high cost and finite supply of indium. Films made from silver or copper nanowires are promising candidates, exhibiting high conductivity and optical transparency in addition to being flexible.

Copper nanowires are typically synthesised by the reduction of Cu2+ in solution to its metal form using the highly toxic and dangerously unstable compound, hydrazine. These copper nano wires can then be incorporated into an ink for the roll-to-roll printing of transparent conductors.

Recently sugar has been used to reduce Cu2+ in solution yielding extremely high aspect ratio copper nanowires via a non-toxic route, though their inherent length and flexibility leads to entanglement and agglomeration, precluding their use in liquid inks.

Copper nanowires are attractive as copper is 100 times cheaper than silver and 1000 times more abundant,this economic synthesis is a big step towards their widespread use in the transparent conductor industry
