High-purity H2 production accompanied with a precise decarbonization opens an avenue to approach carbon-neutral society. Metal-organic framework nanosheet membranes provide great opportunities for accurate and fast /CO2 separation, CO2 leakage through the membrane interlayer galleries decided ultimate separation accuracy. Here we introduce low dose amino side groups into Zn2 (benzimidazolate)4 conformation. Physisorbed served as linkers, gently regulated stabilized spacing. These evoked synergistic effect of adsorption-assisted molecular sieving steric hinderance, whilst exquisitely preserving apertures high-speed transport. The optimized set new record ultrathin in (mixture factor: 1158, permeance: 1417 gas permeation unit). This strategy provides effective way customize desirable ability.

Efficient propyne/propylene separation to obtain polymer-grade propylene is a crucial and challenging process in industrial production, but it has not yet been realized the covalent organic framework (COF) field. Addressing this challenge, we synthesize two three-dimensional COF adsorbents via [8 + 4] construction approach based on an octatopic aldehyde monomer. Upon using continuous rotation electron diffraction technique structural simulation, both COFs are successfully determined as rare flu topology. Various characterization techniques prove that exhibit high crystallinity, porosity, good stability. Attributed their interconnected micropores nonpolar pore environment, these can efficiently remove trace amounts of propyne from (1/99, 0.1/99.9, v/v) mixture high-purity (>99.99%), validated by dynamic breakthrough experiments. This work paves new avenue for highly efficient adsorbents.

Sustainable and energy-efficient molecular separation requires membranes with high permeability selectivity. Among various membranes, the mixed matrix (MMMs) prepared from two-dimensional MXene materials well-defined nanochannels are expected to be used for precise of molecules. However, stacking a large number 2D nanosheets creates gas mass transfer barriers, resulting in significant reduction permeability. To solve this issue, herein, high-performance self-supporting Pebax/CMC@MXene MMM was by combination branched carboxymethyl cellulose (CMC) CO2 natural flue gas. Gas experimental results show that as-prepared MMMs can significantly improve permeance When loading CMC@MXene filler fixed at 1.5 mg/mL, found 521 GPU, CO2/N2 selectivity calculated 40.1. Meanwhile, measured 444 CO2/CH4 40.4. In addition, resulted possesses excellent thermal stability long-term durability; after 60 h test, its performance has no obvious change.
