Hydrous oxide

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

Some of them (eg HFO, HAO) are precipitated in highly porous poorly crystaline or amorphous forms and therefore good adsorbents used eg in water treatment, [5] see also Ferrihydrite.

Some others are gels.

Various hydrous oxide films may be used an various applications such as electrocatalysis, supercapacitors, sensors, etc.[6] [7]

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