  • 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

Nanomaterials are an increasingly important product of nanotechnologies. normally defined as being smaller than 100nm in one dimension at least. We offer inorganic nanopowders, nanoparticles, dispersions, and surface-functionalized nanoparticles

Nanomaterials are coming into healthcare, electronics, cosmetics, ceramic industry, textile industry , environmental protection, engineering industry, functional materials and other areas. Their physical and chemical properties often differ from  those of bulk materials.

Descriptions of nanomaterials ought to include the average particle size, allowing for clumping and a description of the particle number size distribution, COA, SEM, TEM.etc. Detailed assessments may include the following:

1. Physical properties of nanomaterials:

Size, shape, specific surface area, and ratio of width and height

Particle size distribution

Structure, including crystal structure and any crystal defects

How well they dissolve

2. Chemical properties of nanomaterials:

Molecular structure

Composition, including purity, and known impurities or additives

Whether it is held in a solid, liquid or gas

Surface chemistry

Attraction to water molecules or oils and fats
