Bismuth(III) oxide - Wikipedia

WebBismuth is a brittle metal with a silvery white color. Its density is 9.7 g/cm 3, its melting point is 271°C, and the boiling point is 1564°C. Bismuth has a number of properties that are decisive for its various applications. It has a low toxicity for humans, and therefore is also called “green bismuth”. WebThe crystalline phase composition and surface structure of Bi2O3 photocatalysts were examined using SEM, XRD, UV-visible spectroscopy, and XPS. Optical characterizations have indicated that the Bi2O3 presents the photoabsorption properties shifting from UV light region into visible light which is approaching towards the edge of 470 nm.
