Question

What are nanocatalysts? Discuss the efficiency of metal nano particle in heterogeneous catalysis?​

Answer 1

Answer:

Nanomaterial-based catalysts are usually heterogeneous catalysts broken up into metal nanoparticles in order to enhance the catalytic process. Metal nanoparticles have high surface area, which can increase catalytic activity. Nanoparticle catalysts can be easily separated and recycled.

Answer 2

Nanocatalysts are the catalyst that has nanoparticles. It has a combination of both heterogeneous and homogeneous catalytic systems. Mostly the nanocatalyst is used in fuel, medicines, etc..

The efficiency of metal nanoparticles in heterogeneous catalysts is as follows:

• Various factors like particle size, shape, chemical composition, etc. affect the efficiency catalytic properties of the metal catalyst.
• The nanocatalysts which have different phases as reactants, are heterogeneous catalysts.
• It has high recoverability and hence is environment friendly.
