A Review on Nanoporous Metals

Abstract

Porous metals are materials that have excellent functional and structural properties. They are lightweight materials with properties such as low bulk density, high surface area, low thermal conductivity, good penetrability, energy management use, noise attenuation, vibration suppression etc. Nanomaterials are a subset of porous materials which have large porosities of 0.4 nm and above and have pore diameters of 1-100nm. Nanoporous metals have high surface to volume ratio, with a high surface area and large porosity and ordered uniform pore structure. The applications that nanoporous materials can be used for are catalysis, separation and sensing, drug delivery, etc. They are used for sensing glucose in a diabetics blood, catalysis of oil into hydrocarbons, encapsulating drugs and allowing for a slow controlled release of the drug and many more applications that have the ability to
