Covalent Triazine Frameworks with Palladium Nanoclusters as Highly Efficient Heterogeneous Catalysts for Styrene Oxidation

Catalytic oxidation of styrene has attracted extensive attention in industries and academia. Benzaldehyde, one the derived valuable aromatic aldehyde products, been extensively applied perfume, pharmacy, dye industries. However, it is difficult to achieve a high yield by transforming into benzaldehyde with sustainable supply active catalysts. Furthermore, conventional catalyst species inevitably suffer permanent catalytic failure, which largely limits product yield. Covalent triazine frameworks (CTFs) have emerged as an excellent platform for heterogeneous catalysis due their regular pore channels large specific surface area. Herein, we report use CTF loaded Pd clusters (DCP-CTF@Pd-MC) heteropore structure oxidize benzaldehyde. The obtained DCP-CTF@Pd-MC stability easy recycle shows activity. striking performance, 95%, can be attributed anchoring more exposed sites. strong coordination pyridine nitrogen atoms enables better chemical stability, especially reactions. Moreover, well-provided transport accelerate mass transfer between reactants products.
