1. Enhancing Moisture and Electrochemical Stability of the Li5.5PS4.5Cl1.5 Electrolyte by Oxygen Doping
Linfeng Peng, Shaoqing Chen, Chuang Yu, Chaochao Wei, Cong Liao, Zhongkai Wu, Hsing-Lin Wang, Shijie Cheng, Jia Xie ACS Appl Mater Interfaces. 2022 Jan 26;14(3):4179-4185. doi: 10.1021/acsami.1c21561. Epub 2022 Jan 17.
Chlorine-rich argyrodite-type solid electrolyte Li5.5PS4.5Cl1.5 has been a promising choice for solid-state batteries (SSBs) because of its ultrafast Li-ion conduction. However, the poor air/moisture stability and low electrochemical stability with pristine high-voltage cathodes hinder their applications. Herein, O-substituted Li5.5PS4.5-xOxCl1.5 (x = 0, 0.075, 0.175, and 0.25) solid electrolytes are successfully synthesized. Among them, Li5.5PS4.425O0.075Cl1.5 delivers high ionic conductivity, improved moisture resistance, and enhanced electrochemical stability in higher voltage windows. SSBs using Li5.5PS4.425O0.075Cl1.5 show higher capacities and superior cyclability than those using Li5.5PS4.5Cl1.5 combined with a pristine LiNi0.8Mn0.1Co0.1O2 cathode when operated at a high end-of-charge voltage of 4.5 V (vs Li+/Li0). Moreover, the batteries exhibit outstanding performance in a wide temperature range. This work provides a strategy to modify the inherent drawbacks of sulfide electrolytes, promoting their practical applications.
2. Coupling of solid-solution and heterojunction in a 2D-1D core-shell-like BiOCl0.5I0.5/Bi5O7I hierarchy for promoting full-spectrum photocatalysis and molecular oxygen activation
Hongwei Huang, Chao Zeng, Ke Xiao, Yihe Zhang J Colloid Interface Sci. 2017 Oct 15;504:257-267. doi: 10.1016/j.jcis.2017.05.048. Epub 2017 May 18.
We herein describe the coupling of solid-solution and heterojunction in a 2D-1D BiOCl0.5I0.5/Bi5O7I hierarchical architecture for optimizing photoabsorption, energy band levels and charge separation, thereby promoting the photo-oxidation and molecular oxygen activation performance. BiOCl0.5I0.5/Bi5O7I shows a core-shell-like structure with BiOCl0.5I0.5 thin nanoflakes (~3 to 8 layers) homogeneously vertical coating on the surface of Bi5O7I strips. The photo-responsive range of BiOCl0.5I0.5/Bi5O7I can be orderly tuned from 450nm to 650nm by increasing the BiOCl0.5I0.5 content. Regardless of visible light (λ>420nm) or UV light (365nm) irradiation, BiOCl0.5I0.5/Bi5O7I casts highly promoted photocatalytic activity in decomposing methyl orange (MO) compared to the BiOCl0.5I0.5 and Bi5O7I. This enhancement on full-spectrum photoreactivity is attributable to the facilitated charge separation derived from BiOCl0.5I0.5/Bi5O7I heterojunction with intimate interfacial interaction, which is approved by transient photocurrent response under visible and UV-vis light. To probe the photocatalytic mechanism, active species trapping tests are performed over BiOCl0.5I0.5, Bi5O7I and BiOCl0.5I0.5/Bi5O7I, which reveal superoxide radical (O2-) and hole (h+) take dominant roles in photo-oxidation reaction. BiOCl0.5I0.5/Bi5O7I was also found possessing a stronger ability in molecular oxygen activation with a O2- production rate of 2.22×10-7molL-1h-1, which far outperforms Bi5O7I (1.35×10-7molL-1h-1) and BiOCl0.5I0.5 (1.54×10-7molL-1h-1). It further corroborates the efficient band charge transfer between BiOCl0.5I0.5 and Bi5O7I. This work may furnish a new concept on smart design of high-performance photocatalytic materials via manipulating multiple strategies.
3. Synthesis and Reduction of Heteroleptic Bis(cyclopentadienyl) Uranium(III) Complexes
Justin C Wedal, Joseph W Ziller, Filipp Furche, William J Evans Inorg Chem. 2022 May 16;61(19):7365-7376. doi: 10.1021/acs.inorgchem.2c00322. Epub 2022 May 3.
Heteroleptic U(III) complexes supported by bis(cyclopentadienyl) frameworks have been synthesized to examine their suitability as precursors to U(II) complexes. The newly synthesized (C5Me5)2U(OC6H2tBu2-2,6-Me-4), (C5Me5)2U(OC6H2Ad2-2,6-tBu-4) (Ad = 1-adamantyl), (C5Me5)2U(C5H5), and (C5Me5)2U(C5Me4H) are compared with (C5Me5)2U[N(SiMe3)2], (C5Me5)2U[CH(SiMe3)2], and (C5Me5)U[N(SiMe3)2]2. An improved synthesis of (C5Me5)2U(μ-Ph)2BPh2 was developed, which was used to synthesize (C5Me5)2U(C5Me4H). Since the X-ray crystal structure of (C5Me5)2U(OC6H2tBu2-2,6-Me-4) contained two very different molecules in the asymmetric unit with 115.7(5)° and 166.0(5)° U-O-Cipso angles, the (C5Me4H)2U(OC6H2tBu2-2,6-Me-4) and (C5Me5)2Ce(OC6H2tBu2-2,6-Me-4) analogues were synthesized and characterized by X-ray diffraction for comparison. Electrochemical studies in THF with a 100 mM [nBu4N][BPh4] supporting electrolyte showed U(IV)/U(III) and U(III)/U(II) redox couples for all the heteroleptic complexes except (C5Me5)2U(C5H5). Chemical reduction of all heteroleptic compounds formed dark blue solutions characteristic of U(II) when reacted with KC8 at -78 °C, but none formed isolable U(II) complexes. The targeted U(II) complexes, [(C5Me5)2U(OC6H2tBu2-2,6-Me-4)]1-, {(C5Me5)2U[CH(SiMe3)2]}1-, [(C5Me5)2U(C5H5)]1-, and [(C5Me5)2U(C5Me4H)]1-, were analyzed by density functional theory, and a 5f36d1 electron configuration was found to be the ground state in each case.
