Common tungstates include sodium tungstate (Na2WO4•2H2O), calcium tungstate (CaWO4), cobalt tungstate (CoWO4) and cadmium tungstate (CdWO4), as well as bismuth tungstate. Physical properties and chemical properties, and widely used in chemical industry and optoelectronics and other fields.
Bismuth tungstate (Bi2O12W3), also known as bismuth tungsten oxide, is a photocatalytic material composed of three elements: tungsten, bismuth and oxygen. -] A covalent compound composed of Bismuth Tungstate or Bismuth Tungsten Oxide in English, the molecular formula is Bi2O12W3, the molecular weight is 1161.75, and the CAS number is 13595-87-4.
In terms of physical and chemical properties, bismuth tungstate (Bi2O12W3) is a green or white irritating crystalline powder with a purity of 99.9%, a melting point of 842°C, insoluble in water, and a narrow band gap (2.80eV). , high photochemical stability and strong oxidation ability. Note: Although this substance can exist stably at normal temperature and pressure, it should avoid contact with light, open flame and high temperature.
The preparation steps of bismuth tungstate (Bi2O12W3) catalytic material are as follows: first dissolve a certain amount of bismuth nitrate and sodium tungstate in water, then put the white precipitate into the reaction tank, and carry out hydrothermal reaction, and cool to At room temperature, finally dry and grind finely. The preparation steps of Bi2O12W3 nanomaterials are: first dissolve a certain amount of bismuth nitrate and sodium tungstate in water, then adjust the pH value with nitric acid and sodium hydroxide, then add an appropriate amount of cetyltrimethylammonium bromide, and then Transfer to reaction tank, carry out heating reaction, cool to room temperature, wash and dry.
Bismuth tungstate can be used as a photocatalytic material. In addition to catalyzing the decomposition of water to produce hydrogen and oxygen, it can also degrade organic pollutants.
