A New Bismuth Potassium Nitrate Oxide, Bi 1.7 K 0.9 O 2 (NO 3 ) 2 : Synthesis, Structure, Thermal Behavior, and Photocatalytic Properties. -The title compound is hydrothermally synthesized from a mixture of Bi(NO3)3 and KNO3 in H2O (tube furnace, 350°C, 2 h). The new compound is characterized by powder XRD, SEM, FTIR, and UV/VIS spectroscopy. Bi1.7K0.9O2(NO3)2 crystallizes in the orthorhombic space group Immm with Z = 2. The structure is completely analogous to that suggested for beyerite, Bi2CaO2(CO3)2. At 440°C the compound transforms to another basic bismuth potassium nitrate, and at 520°C the intermediate oxide nitrate decomposes into a mixture of crystalline α-Bi2O3 and KNO3. Bi1.7K0.9O2(NO3)2 exhibits low photocatalytic activity for decomposition of rhodamine B and photooxidation of KI in neutral media under irradiation at 385-740 nm, and completely converts to Bi 5 O 7 I after reaction with KI in alkaline media. -(SHENAWI-KHALIL, S.; UVAROV*, V.; CHARKIN, D.
