A recyclable self-assembled composite catalyst consisting of Fe3O4-rose bengal-layered double hydroxides for highly efficient visible light photocatalysis in water.

The first case of a highly efficient layered double hydroxide (LDH) supported organic visible light photocatalyst is reported and it can catalyze various organic transformations with high efficiency in water under visible light irradiation.

Directed Aromatic C-H Activation/Acetoxylation Catalyzed by Pd Nanoparticles Supported on Graphene Oxide.

The first solid-supported directed aromatic C-H activation/acetoxylation has been successfully developed by using palladium nanoparticles supported on graphene oxide (PdNPs/GO) as a catalyst. The practicability of this method is demonstrated by simple preparation of catalyst, high catalytic efficiency, wide functional group tolerance, and easy scale up of the reaction. A hot filtration test and Hg(0) poisoning test indicate the heterogeneous nature of the catalytic active species.
