A new bismuth potassium nitrate oxide, Bi1.7K0.9O2(NO3)2: Synthesis, structure, thermal behavior, and photocatalytic properties

Layered Bismuth Oxyfluoride Nitrates Revealing Large Second-Harmonic Generation and Photocatalytic Properties

“…IR spectra exhibited Bi–O or Bi–F, and N–O vibrations in the title materials. While the peaks occurring at 415–558 cm –1 can be assigned to Bi–O/F vibrations, those occurring at 812–874 cm –1 and 1311–1384 cm –1 are due to the peaks for N–O bending and stretching vibrations, respectively, for nitrates. − …”

A new anhydrous bismuth potassium nitrate, K3Bi2(NO3)9: Synthesis, structure characterization and thermal decomposition

“…We presented here a part of the results obtained under the ongoing experimental study aimed at a development of new Bi-based photocatalysts with using Bi(NO 3 ) 3 ·5H 2 O as source of bismuth. Other new phases discovered in reaction products obtained in due course of this study were reported in [13,15,16]. We believe that that detailed information about structure, morphology, chemical composition and thermal stability of the newly found K 3 Bi 2 (NO 3 ) 9 phase would be of interest for diverse sections of research community.…”

“…XRD patterns from 5 • to 90 • 2Â were recorded at room temperature using CuK␣ radiation ( = 0.15418 nm) with following measurement conditions: step scan mode with a step size 0.02 • 2Â and counting time of 1 s per step for preliminary study and 12 s per step for structural refinement. TOPAS-v.3 [17] software was used for structure refinement.…”

Pb6O5(NO3)2: A Nonlinear Optical Oxynitrate Structurally Based on Lead Oxide Framework

“…7,8 In this respect, nitrate is of particular interest being, on the one hand, an isoelectronic analogue of borate, 5 and on the other hand, a crystal chemical analogue of halides. 9 In addition, nitrates do not cause coloring, contrary to halides (particularly in lead oxyiodides), which is important for optical transparency. Recent findings of NLO materials among fluoride and oxide halides of lead 4,5 prompted us to study lead oxide nitrates starting from the binary lead oxide−lead nitrate system.…”

“…In possession of a stereochemically active lone pair and high polarizability, the divalent lead cation contributes to a multitude of high-performance materials ranging from ferroelectrics (e.g., PZT) to nonlinear optical materials. The chemistry of the latter is particularly versatile ranging from hydroxide nitrates , to recently reported fluoride/oxide halides − and halide borates. , In this respect, nitrate is of particular interest being, on the one hand, an isoelectronic analogue of borate, and on the other hand, a crystal chemical analogue of halides . In addition, nitrates do not cause coloring, contrary to halides (particularly in lead oxyiodides), which is important for optical transparency.…”
