Pyrolysis of functional cellulose by ionothermal method to synthesis of mesoporous triazine carbon for supporting of Pd and its application.

A mesoporous triazine-based carbon (MTC) supported Pd nanoparticles was synthesized and found to be a retrievable and efficient heterogeneous catalyst for Heck cross-coupling reaction between various aryl halides and alkenes. The MTC-supported Pd catalyst is synthesized by ionothermal methodology followed by high temperature pyrolysis of functional cellulose (Cell-CN) and trimerization of nitrile groups in the presence of ZnCl2. A combination of different analysis such as FT-IR, Raman, XRD, FE-SEM, HRTEM, N2 adsorption-desorption isotherm and TGA confirm the successfully preparation of catalyst. The presence of ZnCl2 and also nitrile groups during pyrolysis process is proved to create a mesoporous structure with high specific surface area (1216.8 m2 g-1) which achieved from BET analysis. This heterogeneous catalyst represents a high stability and catalytic activity towards Heck cross-coupling reaction in optimized reaction condition.
