Gold supported iron oxide–hydroxide derived from iron
2009.4.15 In this investigation, an attempt has been made to prepare iron oxide–hydroxide (FeOOH) from iron ore tailings, which is considered as waste material in iron ore industry. It is used as a support for nano-gold particles to study its performance
Iron(II) hydroxide or ferrous hydroxide is an inorganic compound with the formula Fe(OH)2. It is produced when iron(II) salts, from a compound such as iron(II) sulfate, are treated with hydroxide ions. Iron(II) hydroxide is a white solid, but even traces of oxygen impart a greenish tinge. The air-oxidised solid is sometimes known as "green rust".
Iron(III) oxide-hydroxide or ferric oxyhydroxide is the chemical compound of iron, oxygen, and hydrogen with formula FeO(OH). The compound is often encountered as one of its hydrates, FeO(OH)nH 2O [rust]. The monohydrate FeO(OH)H 2O is often referred to as iron(III) hydroxide Fe(OH) 3, hydrated iron oxide, yellow iron oxide, or Pigment Yellow 42.
