Abstract Shuttle effect and sluggish redox kinetics of sulfur species still hinder the practical application lithium‐sulfur batteries (LSBs). Herein, a strategy integrating sub‐nano catalysts into metal‐organic framework (MOF) is proposed for developing efficient host to tackle these issues. The designed MOF (MOF‐TOC) endowed with TiO clusters (TOCs) in mesopores can act as an reaction chamber LSBs. Systematic electrochemical measurements calculations demonstrate that MOF‐TOC trap confine...
Solid-state batteries (SSBs) hold immense potential for improved energy density and safety compared to traditional batteries. However, existing solid-state electrolytes (SSEs) face challenges in meeting the complex operational requirements of SSBs. This study introduces a novel approach address this issue by developing metal-organic framework (MOF) with customized bilayer zwitterionic nanochannels (MOF-BZN) as high-performance SSEs. The BZN consist rigid anionic MOF channel chemically...
Metal–organic frameworks (MOFs) have attracted intensive study as solid electrolytes (SEs) in recent years. However, MOF particles work separately SEs and numerous interfaces hinder a high-efficiency ion transport, which lowers the performance of solid-state batteries (SSBs). Herein, continuous ion-conductive paths were constructed by cross-linked chains. Chains newly developed (Zr-BPDC-2SO3H) grown on bacterial cellulose (BC) nanofibers to provide transport network. The chains exhibit high...
Metal–organic frameworks (MOFs) have been attracting a great deal of attention as potential solid electrolytes (SEs). However, the interfacial compatibility MOF-based SEs caused by physical contact among MOF particles, polymer binder, and electrodes is not yet fully determined. Herein, bioinspired design strategy aiming to build ion transport pathways at interfaces was introduced. The MOF-to-MOF paths were built via in situ ring opening epoxide, akin protein molecules that across cell walls....
Co3O4/In2O3 nanocomposites were prepared via a microwave-hydrothermal method and directly used as photoanodes for the photoelectrocatalytic (PEC) process to reduce Cr(VI). The as-prepared composites show rod-like structure, which is composed of nanoparticles. PEC experiments indicated that after 120 min irradiation with 0.7 V bias voltage visible light, Cr(VI) reduction efficiency in aqueous solution was 100%, superior samples by other methods. Moreover, composite still had high catalytic...
Although solid-state batteries (SSBs) are high potential in achieving better safety and higher energy density, current electrolytes (SSEs) cannot fully satisfy the complicated requirements of SSBs. Herein, a covalent organic framework (COF) with multi-cationic molecular chains (COF-MCMC) was developed as an efficient SSE. The MCMCs chemically anchored on COF channels were generated by nano-confined copolymerization cationic ionic liquid monomers, which can function Li+ selective gates....

Metal–organic frameworks (MOFs) have shown potential for trapping and catalyzing lithium polysulfides (LiPSs) in lithium–sulfur batteries (LSBs), which is, however, challenging, because their catalytic metal centers are usually fully coordinated with ligands inactivated.
