BiS nanorod-stacked hollow microtubes self-assembled from bismuth-based metal-organic frameworks as advanced negative electrodes for hybrid supercapacitors.

Bismuth sulfide (Bi2S3) with a lamellar structure has emerged as a promising negative electrode material for supercapacitors (SCs) due to its high theoretical specific capacity. Meanwhile, the improvement of electrochemical properties strongly depends on the size, shape and morphologies of Bi2S3 nanomaterials. Herein, the hierarchical Bi2S3 nanorod-stacked hollow microtubes are self-assembled through a facile self-sacrificing template strategy from bismuth-based metal-organic framework microprisms.

Hierarchical core-shell SiO@PDA@BiOBr microspheres with enhanced visible-light-driven photocatalytic performance.

To explore catalysts combining highly accessible specific surface areas with low recombination of the photo-induced electron-hole pairs, a novel SiO@PDA@BiOBr composite photocatalyst with a hierarchical core-shell structure was prepared by a facile solvothermal method.

A hierarchical NiO/NiMn-layered double hydroxide nanosheet array on Ni foam for high performance supercapacitors.

A hierarchical NiO/NiMn-LDH nanosheet array on Ni foam was prepared via a facile two-step approach and exhibited a high specific capacitance (937 F g at 0.5 A g) and good cycling stability (91% retention after 1000 cycles at 5 A g). The improved electrochemical performance is benefited from the synergistic properties of hierarchical NiO/LDH nanosheet composites on a conductive substrate.

Enhanced photocatalytic performance of BiOBr/NH-MIL-125(Ti) composite for dye degradation under visible light.

A Naphthalenediimide-Based Metal-Organic Framework and Thin Film Exhibiting Photochromic and Electrochromic Properties.

A multifunctional metal-organic framework, NBU-3, has been explored as a 2D three-connected network based on a naphthalenediimide-based ligand.

NBU-3 is the first example of MOF materials containing both photochromic and electrochromic properties, which can be desirable for thin film devices.

Doubly interpenetrated chiral (10,3)-a network with charge-transfer-type guest inclusion.

A doubly interpenetrated metal-organic framework, [Zn(3)(TATB)(2)(H(2)O)(2)](n) (2), with chiral (10,3)-a topology, has been synthesized from an achiral, trigonal-planar ligand, 4,4',4″-s-triazine-2,4,6-triyltribenzoate (TATB).
