Abstract null null The membranes based on graphene oxide (GO) have shown vast perspectives in nanofiltration, while the swelling of GO membranes in water environment poses a critical challenge for practical applications. In this study, we report the simple fabrication of stable GO membranes in water environment through intercalating multiple “plug-ins”: the filter of β-cyclodextrin (β-CD) and the crosslinker of trimesoyl chloride (TMC), which can significantly enhance sieving effect and stabilit...

Abstract null null The low conductivity of nickel phosphate hinders its application as electrode for electrochemical energy storage applications, although its environmental and biological benign, as well as the low cost, are superior advantages compared with other transition metal based electrode materials. Herein, the “bottom-up” self-assembly of Ni-MOF amorphous nanospheres on MXene nanosheets, which provide rich nucleation sites for MOF growth, is achieved, and the MOF nanospheres are subsequ...

Metal–organic framework (MOF) membranes with an ultra-small pore size (<4 A) have shown great prospects in the highly selective separation of small gas molecules such as hydrogen, but their narrow channels may result in a low gas permeance. To improve the gas permeance of ultra-microporous MOF membranes, a stable covalent organic framework (COF) with large and uniform pores is doped to construct a binary COF/MOF all-nanoporous composite (ANC) membrane, equivalent to reducing the effective membra...

The calcium squarate with a rigid framework is found to exhibit volumetric negative thermal expansion (NTE) with the coefficient −9.51(5) × 10−6 K−1 and uniaxial zero thermal expansion (ZTE, −0.14(4) × 10−6 K−1) over a wide temperature. Detailed comparison of the long–range and local structure sheds light on the fact that the anomalous thermal expansion originates from the transverse vibration of the bridging squarate ligand, although it has been tightly bonded by five calcium ions. We believe t...

The construction of a porous carbon structure with a high specific surface area is conducive to enhanced electrocatalytic activity due to the accessibility of active sites and improvement of the mass transfer. Herein, we explored the possibility of using micelles of mesoporous silica (MCM-48) as the carbon source to generate porous carbon under the confinement of MCM-48 channels. The complexes formed by Co2+ and 4,4'-bipyridine were in situ incorporated into the micelles to derive Co-related act...

Abstract Precise control of the pore size and environment of metal–organic framework (MOF) is a necessary condition for achieving high performance of gas adsorption and separation. After nearly two decades of development, the synthesis of MOF materials has gradually evolved from exploration and trial to precise-design, including function-oriented microstructure design and optimization, pore size tailoring, and secondary building unit (SBU) modification. The unique pore environments of MOF materi...

Layered MoSe2 with a large interlayer has been regarded as an attractive host for larger-sized Na+/K+ ions. Nevertheless, serious volume effects and aggregation trends upon cycling are still great challenges for sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs). Herein, MoSe2/N,P-doped carbon nanospheres with double-shells of N-doped carbon and few-layered MoSe2 nanosheets (MoSe2/N,P–C@N–C⊂MoSe2) are synthesized through a tailored template of metal–organic networks. This core–double...

Metal–organic framework (MOF) membranes with sub-nanometer channels have great potential in molecule selective transport, but the scalable and facile fabrication of flexible and thin membranes from stable MOF structures is difficult, which is the key to realizing practical applications. In this work, stable and ultra-small MOF nanoparticles act as “ordered porous monomers” and are interfacially polymerized with organic monomers into ultra-thin and flexible membranes. An ∼150 nm thin MOF active l...

Abstract null null Rechargeable alkaline battery is a potential high-powered next-generation electrochemical energy storage equipment. However, the inferior energy density, compare with other electrochemical energy technologies, restrict its further practical applications. To address this, the rational design and optimization of electrode is of significance. Herein, we demonstrate the construction of high energy density NiCo/Bi alkaline battery by controllable MOF hydrolysis. Specifically, the h...
