What is Aerogel?
• Is essentially the solid framework of a gel
• A class of porous, solid materials that exhibit extreme material properties

density Very good thermal
insulator High specific
surface area Lowest dielectric
constant

Introducing Metal Aerogels!• Inorganic cousins of
the more common Silica Aerogel
• Until very recently, Metal Aerogels did not exist!

What are its properties?
High specific surface area (100-500m2/g)
Electrically conductive!
Enhanced catalytic activity
Surprisingly capable thermal insulator
