Chemistry:Hydrous oxide

From HandWiki

Hydrous oxides are inorganic compounds of a metal, hydroxide, and weakly bound water. Some examples include:

  • Hydrous ferric oxide (HFO)[1]
  • Hydrous cupric oxide[2]
  • Hydrous thorium oxide (THO) and hydrous titanium oxide (TiHO) [3]
  • Hydrous aluminum oxide (HAO)[4]

Some of them, such as HFO and HAO, are precipitated in highly porous poorly crystalline or amorphous forms and therefore are good adsorbents used for example in water treatment.[5]

Some others are gels.

Hydrous oxide films may be used an various applications such as electrocatalysis, supercapacitors, and sensors.[6][7]

HFO and HAO may also result from oxidative weathering of rocks to produce iron an aluminum hydrous oxide clay soils.[8]
