Abstract

Anhydrous basic bismuth nitrate Bi₆(NO₃)₂O₇(OH)₂ was shown to be produced by reacting bismuth nitrate with aqueous ammonia under microwave-assisted hydrothermal treatment as a result of hydrolysis. The composition of the basic nitrate was verified by titration, CHNS analyses, DTG, and IR spectroscopy. Photocatalytic tests showed that Bi₆(NO₃)₂O₇(OH)₂ has a photocatalytic activity, but its properties are interior to those of α-Bi₂O₃.
