Ionic Liquid-Controlled Growth of NiCo 2 S 4 3D Hierarchical Hollow Nanoarrow Arrays on Ni Foam for Superior Performance Binder Free Hybrid Supercapacitors. SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2019; 15:e1804318.

Abstract
A significant development in the design of a NiCo2 S4 3D hierarchical hollow nanoarrow arrays (HNA)-based supercapacitor binder free electrode assembled by 1D hollow nanoneedles and 2D nanosheets on a Ni foam collector through controlling ionic liquid 1-octyl-3-methylimidazolium chloride ([OMIm]Cl) concentration is reported. The unique NiCo2 S4 -HNA electrode acquires high specific capacity (1297 C g-1 at 1 A g-1 , 2.59 C cm-2 at 2 mA cm-2 ), excellent rate capability (maintaining 73.0% at 20 A g-1 ), and long operational life (maintaining 92.4% after 10 000 cycles at 5 A g-1 ), which are superior to those for 1D hollow nanoneedle arrays (HNN) and 2D porous nanoflake arrays (PNF). The outstanding electrochemical performance is attributed to the novel 3D structure with large specific surface, hollow cores, high porosity as well as stable architecture. In addition, a hybrid supercapacitor applying 3D NiCo2 S4 -HNA as the positive electrode and active carbon as the negative electrode exhibits a high energy density of 42.5 Wh kg-1 at a power density of 2684.2 W kg-1 in an operating voltage of 1.6 V. Robust cycling stability is also expressed with 84.9% retention after repeating 10 000 cycles at 5 A g-1 , implying their great potential in superior-performance supercapacitors.

Abstract
Hexagonal (h-WO3) mesocrystals with biconical morphology were prepared by a straightforward ionic liquid-assisted hydrothermal route and investigated as anodic materials for lithium-ion batteries. Compared to the alternatives, the biconical tungsten trioxide mesocrystal exhibited excellent lithium insertion with good cyclability and rate capability, making it a promising candidate as the anode material for high-performance lithium-ion batteries.

Abstract
Libethenite Cu2PO4OH nanocrystals with different morphologies were prepared by an ionic liquid-assisted hydrothermal route, and were further investigated as photocatalysts under visible-light irradiation. The Cu2PO4OH elongated truncated bipyramids exposing {100} facets exhibit superior photocatalytic activity compared to other particles, which can be attributed to the presence of 100% Cu5c atoms on {100} facets. It is highly expect this research can provide a useful fundamental understanding of shape-dependent photocatalytic performance of copper hydroxyphosphate.
