Three-Dimensional (3D) Ordered Macroporous Bimetallic (Mn,Fe) Selenide/Carbon Composite with Heterojunction Interface for High-Performance Sodium Ion Batteries

ACS Applied Materials & Interfaces (2023)

Jiuwu Wang Xianfeng Yang Caini Yang Yi Dai Siyao Chen

Transition-metal selenides have captured significant research attention as anode materials for sodium ion batteries (SIBs) due to their high theoretical specific capacities and excellent electronic conductivity. However, volumetric expansion and inferior cycle life still hinder their practical application. Herein, a three-dimensional (3D) ordered macroporous bimetallic (Mn,Fe) selenide modified by a carbon layer (denoted as 3DOM-MnFeSex@C) composite containing a heterojunction interface is fabricated through selenizing a 3D ordered macroporous Mn-based Prussian Blue analogue single crystal. The 3DOM-MnFeSex@C exhibits hierarchically porous architecture with enhanced mass-transfer efficiency; MnSe and FeSe2 particles are encapsulated into macroporous carbon framework, which can significantly promote the electronic conductivity and maintain the structural integrity. The density functional theory calculation indicates that the heterojunction interface between MnSe and FeSe2 has been successfully engineered so that Na+ can be readily adsorbed and rapidly converted, thus promoting the reaction kinetics and extending the cyclic life. As expected, the 3DOM-MnFeSex@C composite delivers excellent rate performance (277.6 mA h g-1 at 10 A g-1), and prolonged cycling life (191.6 mA h g-1 even after 1000 cycles at 2 A g-1) as a sodium storage anode. The sodium storage mechanism of the composite was further investigated by in situ X-ray diffraction and ex situ high-resolution transmission electron microscopy characterization techniques.

A new carbazolyl‐basedacylphosphine oxide photoinitiator with high performance and low migration

Journal of Polymer Science (2021)

Yinping Wu Rui Li Jiuwu Wang Yue Situ Hong Huang

Abstract In order to obtain a new photoinitiator with high efficiency, low migration, and high solubility in acrylate monomers, a new compound named 9‐allyl‐9 H ‐carbazol‐3‐yldipenylphosphine oxide (ALPO) was designed and synthesized. Compared to 9‐ethyl‐9 H ‐carbazol‐3‐yldipenylphosphine oxide, the double bond conversion (DC) and solubility of ALPO in acrylic monomers were greatly improved, and the migration rate was greatly reduced after replacing the ethyl group in the molecule with an allyl group. Compared with (2,4,6‐trimethylbenzoyl) diphenylphosphine oxide (TPO), which was widely used commercially, ALPO had a higher DC and lower migration rate. This means that ALPO may be able to replace TPO in the light curing field.

Electrochemical Charge/Discharge Cycling and Morphological Effects in Mno2/Panc Nanostructures for Supercapacitors

SSRN Electronic Journal (2022)

Xian Sun Jiuwu Wang Chenguang Huang Yinping Wu Yue Situ

The improvement of electrochemical properties of MnO 2 has been an attractive topic for a long time. Here, MnO 2 /polyacrylonitrile carbon (MnO 2 /PANC) nanostructures with well-modified morphology and crystal phase are required by chemical direct synthesis for high-energy asymmetric supercapacitors. The formation process of the different MnO 2 /PANC nanostructures is investigated in detail, and their application as supercapacitors materials. The cycling stability and specific capacitance performance of MnO 2 /PANC electrode are enhanced during electrochemical cycling and explored to be closely related to the internal morphologies and crystal form of the various MnO 2 /PANC nanostructures. Further, the resulting electrode exhibits the unique nanostructure, in which the defect regions is embedded and highly dispersed in the untrathin MnO 2 /PANC nanostructure; such unique core-shell nanostructure form during charge/discharge cycling, providing more structural defects, increased surface area and rich functional groups, and subsequently, enhanced electrochemical capacitance performance. Therefore, this work suggests a new concept for the development of manganese-based electrode materials with enhanced performance and may have broad application in high-energy storage devices.

Here, MnO 2 /polyacrylonitrile carbon (MnO 2 /PANC) nanostructures with well-modified morphology are required by chemical direct synthesis. The cycling stability and specific capacitance performance of MnO 2 /PANC electrode are enhanced during electrochemical cycling and explored to be closely related to the internal morphologies and crystal form of the various MnO 2 /PANC nanostructures. The Na + ion and PANC are forced to interact with increased active sites of the MnO 2 /PANC surface by cycling protocol. The resulting electrode exhibits the defective nanostructure, in which the Mn-O-C bond is introduced and comprehensive Mn valence accurred in the untrathin MnO 2 /PANC nanostructure; such unique core-shell nanostructure, providing more structural defects, increased surface area and rich functional groups, and subsequently, enhanced electrochemical capacitance performance. Therefore, this work suggests a new concept for the development of manganese-based electrode materials with enhanced performance and may have broad application in high-energy storage devices.
