                                                    Nano Gold Au Particles used as Nano gold catalyst

Spec: 20-30nm, 99.95% 


Application for nano gold particles:

The maximum application of nano gold powder that is the nano-gold catalyst. Supported gold nanoparticles catalyst for water gas shift reaction, various reaction system hydrogenation of unsaturated hydrocarbons and certain types of liquid-phase oxidation reaction of alcohols have a good catalyst.

1. When gold nanoparticles deposited on the metal oxide or by co-precipitation manner when the load is high catalytic activity, especially in the low-temperature catalytic oxidation of CO in the process of CO2, which catalyzes the capacity and efficiency is much higher than other precious metals.

2. Load nano-gold particles can catalyze propylene as PO, epoxidation reaction can be completed in just one step, and in addition to the water does not produce other byproducts.

3. A distinctive feature of the gold catalyst is partially hydrogenated very selective hydrogenation reaction of unsaturated hydrocarbons have an important impact.

4. In addition to the activated carbon, but to Al2O3 and TiO2 as the carrier also make gold nanoparticles have high activity and selectivity.

5. On the water - gas shift reaction, the catalytic activity of Au / Fe2O3 and Au / ZrO2 is high, and the higher the degree of crystallinity of the carrier, the higher the catalytic activity.
