- Description
- We report on the synthesis of mesoporous graphitic C₃N₄ (MGCN-6) with 3D porous structure and Ia3d symmetry and controllable surface properties through a simple polymerization of an environmentally benign and non-toxic guanidine hydrochloride as a C and N precursor using KIT-6 with variable pore sizes as templates for Suzuki coupling reaction. The pore diameters (3.1-4.2 nm), specific surface areas (207-303 m2 g-1), and the specific pore volumes (0.58-0.71 cm3 g-1) of the MGCN-6 materials are finely controlled by varying the pore size of the templates used. The nano cavities of MGCN-6 with the highest specific surface area and a free amine groups are effectively utilized to chelate with Pd(OAC)₂ and applied the prepared catalysts for Suzuki coupling reaction between aryl halides with phenylboronic acid derivatives under very mild and sustainable reaction conditions. The Pd(OAC)₂/MGCN-6 is found to be very active and stable and exhibits an excellent reactivity and selectivity for all of substrates regardless of aryl halides with electron-withdrawing and electron donating groups at room temperature. The activity of the Pd(OAC)₂/MGCN-6 is much higher than that of non-porous bulk graphitic carbon nitride and 2D mesoporous carbon nitride.
