Heterogeneous catalysis is significantly enhanced by the use of highly porous polymers with specific functionalities, such as basic groups, which accelerate reaction rates. Polymers of intrinsic microporosity (PIMs) provide a unique platform for catalytic reactions owing to their high surface areas and customizable pore structures. We herein report a series of Tröger's base polymers (TB-PIMs) with enhanced basicity, achieved through the incorporation of nitrogen-containing groups into their repeat units, such as triazine and triphenylamine.

The NASICON-type NaV(PO) (NVP) is recognized as a potential cathode material for Na-ion batteries (SIBs). Nevertheless, its inherent small electronic conductivity induces limited cycling stability and rate performance. Carbon coating, particularly N-doped carbon, has been identified as an effective strategy to address these challenges.

ConspectusFor chemical reactions with complex pathways, it is extremely difficult to adjust the catalytic performance. The previous strategies on this issue mainly focused on modifying the fine structures of the catalysts, including optimization of the geometric/electronic structure of the metal nanoparticles (NPs), regulation of the chemical composition/morphology of the supports, and/or adjustment of the metal-support interactions to modulate the reaction kinetics on the catalyst surface. Although significant advances have been achieved, the catalytic performance is still unsatisfactory.

NaV(PO), based on multi-electron reactions between V/V/V, is a promising cathode material for SIBs. However, its practical application is hampered by the inferior conductivity, large barrier of V/V, and stepwise phase transition. Herein, these issues are addressed by constructing a medium-entropy material (NaVTiAlCrMnNi(PO), ME-NVP) with strong ME─O bond and highly occupied Na2 sites.

Alkaline phosphatase (ALP) is a nonspecific phosphatase, and its interaction with substrates mainly depends on the recognition of phosphate groups on the substrate. Previous enzymatic research has focused mainly on the enzymatic reaction kinetics of the inorganic small molecule p-nitrophenol phosphate (pNPP) as a substrate, but its interaction with biomacromolecule substrates has not been reported. In current scientific research, ALP is often used for molecular cloning, such as removing the 5' termini of nucleic acids.
