Advanced oxidation processes (AOPs) have demonstrated an effective wastewater treatment method. But the application of AOPs using nanomaterials as catalysts is challenged with a series of problems, including limited mass transfer, surface fouling, poor stability, and difficult recycling. Recently, metal-organic frameworks (MOFs) with high tunability and ultrahigh porosity are emerging as excellent precursors for the delicate design of the structure/composition of catalysts and many MOF-derived catalysts with distinct physicochemical characteristics have shown optimized performance in various AOPs.

Copper-based MOF (Cu-PABA) was selected to immobilize laccase (Lac) at optimum pH because of its favorable acid resistance. Cu-PABA@Lac biocomposites were synthesized in situ by the one-step method under moderate conditions (water environment and normal temperature and pressure). Cu-PABA@Lac had great potential to maintain stability due to the protection of the Cu-PABA shell and reasonable conformational changes.

A stereoselective synthesis of (E)-vinyl sulfones has been developed via electrochemical oxidative N-S bond cleavage of aromatic sulfonylhydrazides, followed by cross-coupling reactions with cinnamic acids to form the C-S bond. The protocol proceeded smoothly to afford (E)-vinyl sulfones in good yields with wide substrate scope under metal-free and halogen-free conditions.
