Polyoxometalates (POMs) are a unique class of molecular metal oxides with tunable structure at the atomic level. They have demonstrated various potential applications in fields. In particular, POMs been widely used as catalysts, due to their facilely modified acid–base properties and redox through designing. Normally, can be utilized both homogeneous heterogeneous where former favors high activity, while latter benefits facile separation catalysts. Faced requirement for sustainable...
Polyoxometalate(POM)-based ionic hybrid nanospheres prepared by protonating and anion-exchanging amino-attached liquid cations with Keggin POM-anions have proven to be highly efficient heterogeneous catalysts for the epoxidation of alkenes H2O2, presenting advantages convenient recovery, steady reuse, simple preparation, flexible composition.
A succinct strategy was demonstrated for constructing a hydroxyl group and imidazolium-bifunctionalized ionic network via one-pot quaternization. Key to success lies in the rational design of multi-imidazole precursor hydroxyl-containing counterpart.

Efficient catalysts are needed to accelerate the conversion and suppress shuttling of polysulfides (LiPSs) promote further development lithium–sulfur (Li–S) batteries. Intermetallic niobium boride (NbB2) has indefinite potential due superior catalytic activity. Nonetheless, lack a rational understanding catalysis creates challenge for design catalysts.

Hydroxylation of benzene is a widely studied atom economical and environmental benign reaction for producing phenol, aiming to replace the existing three-step cumene process. Aerobic oxidation with O2 an ideal dream process, but are so inert that current systems either require expensive noble metal catalysts or wasteful sacrificial reducing agents; otherwise, phenol yields extremely low. Here we report dual-catalysis non-noble system by simultaneously using graphitic carbon nitride (C3N4)...
