“…These dimeric units form layers in the ab plane through the edge sharing of O4 and O6 of the CSO 3 – group. This layer is structurally related to the layers observed in [Bi 2 O 2 (OH)(NO 3 )] . The organic moiety connects the layers to form a dense three-dimensional CP (Figure ).…”

With the employment of high-throughput methods, the system Bi/4,8-disulfonyl-2,6-naphthalenedicarboxylic acid (HDSNDC)/HO/additive (HNO or NaOH) was systematically investigated under hydrothermal reaction conditions. The influence of the molar ratio of the starting materials, pH, and reaction temperature and time was investigated in more than 500 reactions. The product formation is highly sensitive toward small changes of the synthesis parameters, but six new bismuth sulfonatocarboxylates were reproducibly obtained starting from clear solutions of the reactants. All compounds were structurally characterized from single-crystal X-ray diffraction data. Fully deprotonated linker ions are found in [BiO(OH)(HO)(DSNDC)] (1), [Bi(OH)(DSNDC)] (2), [BiO(OH)(HO)(DSNDC)] (3), and [BiO(OH)(HO)(DSNDC)]·4HO (4), while the presence of larger amounts of acid or short reaction times leads to compounds with noncoordinating -COOH groups, [Bi(OH)(HO)(DSNDC)(HDSNDC)] (5) and [BiO(OH)(HO)(HDSNDC)]· xHO (6), respectively. The inorganic building units (IBUs) in all six structures differ substantially from each other; the IBUs found in 2 ({Bi(OH)}), 5 (BiO polyhedron), and 6 ({BiO(OH)} cluster) have been reported in the literature, while new IBUs are observed for 1 (chains of composition {BiO(OH)}), 3 ({BiO(OH)} cluster), and 4 ({BiO(OH)} cluster). Systematic variation of the reaction temperature and time indicated their distinct influence on product formation. Hence, in situ powder X-ray diffraction measurements at Deutsches Elektronen-Synchrotron, Hamburg, Germany, employing synchrotron radiation were carried out. In all studied in situ reactions, compound 6 is first observed and subsequently transformed to 1, 2, 4, and 5, depending on the reaction time and temperature as well as concentration of the starting materials.

“…Recently, two new Sillén-structure-related photocatalysts, Bi 2 O 2 [BO 2 (OH)] and Bi 2 O 2 (OH)(NO 3 ), have been reported by our group. Interestingly, they not only contain layered structures that are constructed by [Bi 2 O 2 ] 2+ /[Bi 2 O 2 (OH)] + layers and alternately interleaved BO 2 (OH) 2– /NO 3 – along the z -axis, but also crystallize in NCS polar crystal structures with monoclinic space group Cm and orthorhombic space group Cmc 2 1 . − The absence of a symmetric center in the local structure could induce a large spontaneous macroscopic polarization to promote the separation of photogenerated electron–hole pairs. , Particularly, Bi 2 O 2 (OH)(NO 3 ) (denoted as BON) was demonstrated to possess superior UV photocatalytic activity, exceeding P25 and some other benchmark photocatalysts, with the generation of • O 2 – and • OH as reactive species. Currently, investigations on BON are very absent, and there are only two other papers reported on BON.…”

Exploration for multiresponsive catalytic materials and synthesis of highly active exposing crystal facets are challenging subjects for catalysis research. In this work, well-defined Bi 2 O 2 (OH)(NO 3 ) nanosheets (BON-S) with a dominantly exposed {001} active facet were synthesized by a sodium-dodecylbenzenesulfonate-assisted (SDBS-assisted) soft-chemical route. BON-S presents far superior photocatalytic activity compared to bulk materials as well as a universal performance for degradation of contaminants and antibiotics under UV light. The profoundly enhanced photocatalytic activity basically stems from the largely shortened diffusion pathway of photogenerated electrons (e − ) and holes (h + ), favoring their migration from bulk to the surface of the catalyst under the internal electric field between [Bi 2 O 2 (OH)] + and NO 3 − layers along the [001] direction. The photocatalytic active species production rates of BON-S are determined to be 3.14 μmol L −1 min −1 for superoxide radicals ( • O 2 − ) and 0.03 μmol L −1 min −1 for hydroxyl radicals ( • OH). BON-S also shows an enhanced visible-light-responsive dye-sensitization degradation activity with Rhodamine B (RhB) as a sensitized medium to provide photoinduced e − . Moreover, for the first time we unearth that Bi 2 O 2 (OH)(NO 3 ) demonstrates an ultrasonic-assisted piezoelectric-catalytic performance for decomposition of methyl orange, bisphenol A, and tetracycline hydrochloride, and • OH dominates the piezoelectric-catalytic process with an evolution rate of 7.13 μmol L −1 h −1 , which far exceeds the photocatalytically induced one. This study may cast new inspiration on developing a new microstructure-design strategy for high photocatalytic/ dye-sensitization performance, and furnishes a novel piezoelectric-catalytic material for environmental applications.

“…Their corresponding XRD patterns and SEM images are displayed in Figure b,c–f, respectively. In brief, the addition of Bi(NO 3 ) 3 ·5H 2 O to a basic aqueous medium leads to its hydrolysis, and the XRD pattern collected on the step-I intermediate shows the formation of BiONO 3 -type phases. , Upon the subsequent addition of Pb(NO 3 ) 2 (step-II) under constant ultrasonication, the former phase has vanished and a new phase, PbBiO 2 NO 3 , is formed. Its crystal structure can be viewed as [PbBiO 2 ] + layers intergrown with single NO 3 – layers along the c -axis (Figure a) .…”

Room-Temperature Synthesis and Stable Na-ion Storage Performance of Two-Dimensional Mixed Lead–Bismuth Oxychloride

et al. 2021

Two-dimensional (2D) mixed-cationic Sillén-type heterostructures have garnered widespread interest in energy conversion and storage applications. However, the current synthesis strategies to prepare them demand a high temperature, longer reaction durations, toxic chemicals, and a complex reaction setup, which hinder their large-scale applications. Herein, we unveil a new rapid room-temperature chemical precipitation route to prepare 2D-PbBiO2Cl within ∼45 min. X-ray diffraction (XRD) and scanning electron microscopy (SEM) mechanistic studies show that its formation proceeds through topotactic ion exchange from an analogous PbBiO2NO3 intermediate. As an anode material in the sodium-ion battery (NIB), this 2D structure displays a stable sodium storage performance (∼240 mAh g–1 for 450 cycles at 100 mA g–1). Most importantly, the combined electrochemical and in operando XRD studies reveal a distinct (de)sodiation process of the 2D-PbBiO2Cl in comparison with the reported Na–(Pb/Bi) phase diagram, which is ascribed to the mixed chemical character of the electrochemically formed nanoscale Bi-rich (Pb/Bi) alloy. This study highlights the feasibility of room-temperature synthesis of 2D mixed-cationic Sillén-type phases and stabilization of their nanoscale alloys, which can potentially exhibit a distinct electrochemical behavior.
