  • 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

Hongwu International Group Ltd,  has set up a specific laboratory to perform testing on nanopowders. The equipment available allows  to perform a complete characterization of nanoparticles and nano-composite materials, in order to guarantee and certify the quality of the raw materials used.

Hongw International Group Ltd provides R&D, customized, production and selling of nano materials,include: elements nanopowders, Sic whisker/powder, nano oxides, nanowires, carbon nanotubes, graphene and so on.

Testing types on nanopowders

XRD Analysis:

Composition of nanomaterial being tested (including degree of purity, known impurities or additives)
Crystalline phase
Crystallite size 

Basic morphology 
Particle size distribution-in dry form
TEM Analysis:
Representative Electron Microscopy (TEM) picture(s)
Particle size distribution – in dry form

SSA analysis: specific surface area of the test is ultra-fine powder material, in particular nano-powders of the most important properties, is important for evaluating the physical properties of their activity, adsorption, catalytic and other properties.

HW NANO materials, With more than 8 years production experience,continuous reform and innovation,now we have a mature production line, special for Sic whisker/powder, precious metal powders, silver nanowires, carbon nanotubes, nano metal alloy powders. Powders with high quality, resonable price, popular sell to all over the world.
