The whence and whither of the metal-organic framework gel. The sequential sol-gel self-assembly and the nonclassical gel-crystal transformation of the UiO-66(Zr) gel are disclosed. The unprecedented intermediate materials during the overall evolutionary processes are prepared “frame-by-frame”. Abstract Metal-organic framework (MOF) gel, an emerging...

This review gives an overview about recent developments in the formation of polymer-based biohybrid nanostructures (PBBNs) via polymerization-induced self-assembly (PISA). PISA outperforms traditional self-assembly techniques regarding efficiency, versatility, simplicity, reproducibility, and nanoparticle yields. Different biohybrid nanostructure architectures...

This paper reports an efficient process for the fabrication of 3D-printed solid polymer electrolytes (SPEs) using photopolymerization-induced microphase separation, enabling control over material nanostructure. The resulting nanoscale bicontinuous structures impart high modulus and high ionic conductivity to SPEs, while 3D printing enables on-demand...

In this work, hollow UiO-66 sphere with biomimetic ion channels based quasi-solid-state electrolytes is prepared. The system is inspired by K+/Na+ ion channels in cell membranes, where biomimetic ion channels formed by the open Zr4+ site can spontaneously bind anions, leaving Li+ as the only mobile species. Meanwhile, the hollow structures can incorporate...

In ideal conditions, the continuous intermediate reactions in oxygen evolution reaction (OER) require active sites with high, moderate, and low Fe/Ni ratios, as well as gradient spatial distribution of them. Here, activating FeS2@NiS2 core–shell structure results in a shell of FexNi1-xOOH with gradient Fe/Ni ratios, thus realizing cascade OER with superior...

Development of highly-catalytic and long-term stable Fe–N–C catalyst using a controllable and efficient N–C coating strategy. The correlation between the thickness of N–C coatings and electrochemical performance is investigated. The stability improvement mechanism of N–C coating is identified to reduce carbon corrosion and iron leaching. Abstract...

Acidity/alkalinity functionalized MOFs into dimethyl carbonate catalysis are first introduced, and the Lewis acidic Pd-NO2-UiO-66 exhibits excellent catalytic performance. In addition to affecting the interaction of Pd(II) and support, the NO2 group has a dominant role in the chemisorption of MN and CO for generating the intermediates COOCH3 *, leading...
