Due to serious global warming and environmental issues, the demand for clean and sustainable energy storage devices is significantly increased. Often accompanied by rapid growth of portable electronic vehicles and devices, massive electromagnetic wave pollution becomes unavoidable. To mitigate the above two issues, this mini-review summaries preparation methods and recent developments of MXene/polyaniline-based composites for their applications in electrochemical devices and electromagnetic interference shielding. Based on excellent synergistic effects between single compounds and designed hierarchical structures, MXene/polyaniline-based composites usually exhibit enhanced physical and chemical properties, showing great potentials in sustainable electrochemical properties and electromagnetic wave protections for human health as well as normal operation of precise electronic devices.

A novel microporous MOF ZJU-16 exhibited high thermal and chemical stability and moderately high selective separation of C₂H₂/CH₄ and CO₂/CH₄.

A methoxy-decorated novel metal–organic framework (MOF), Cu₂(DTPD) (ZJU-12, H₄DTPD = 5,5′-(2,6-dimethoxynaphthalene-1,5-diyl)diisophthalic acid) with optimized pore space and open metal sites, was solvothermally synthesized and structurally characterized. The activated ZJU-12a displays a moderately high BET (Brunauer–Emmett–Teller) surface area of 2316 m² g⁻¹. Due to the pore size of the crystal being consistent with the molecular size and kinetic diameters of C₂H₂ and CO₂, ZJU-12a exhibits a high C₂H₂ storage capacity of 244 cm³ g⁻¹ and CO₂ capture capacity of 134 cm³ g⁻¹ at room temperature.
