  • 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

Li-ion Battery Separator Coating Alumina Nanopowder alpha Al2O3 Nanoparticle 

Specification of Al2O3 nanopowder:

Phase and size: 

alpha: 100-200nm, 0.3um, 0.5um, 1um

gamma: 20-30nm

Purity: 99.7%-99.99%

Color: white



The nano alumina ceramic coating provides a skeleton for the flexible seperator, improves the wear resistance of the seperator, prevents lithium dendrite from piercing, reduces heat shrinkage, improves temperature resistance, and the pores are stable with temperature, which can effectively improve the safety performance of the battery.

The main requirements fo rnano alumina powder for seperator ceramic coating are:

(1) High chemical purity (99.5-99.99%);

(2) The particle size is superfine, the particle size distribution is narraw, the deposited pores are uniform, and the pore permeability is high;

(3) The particle shape is like spherical, the crystallinity is high, the specific surface area is small, the oil absorption rate is low, the coating process is effectively improved, and the coating is thin and uniform.
