Abstract:
Abstract A new N^C^N palladium pincer complex (C10) containing ligand (L4), was synthesised from [PdCl2(CH3CN)2] and fully characterised by spectroscopic and analytical techniques. Its catalytic activity in hydrogenation of CO2 to formate studied. Its nanoparticle nature (N^C^N-Pd/NPs) was established using UV-vis spectroscopy and high-resolution microscopic techniques such as HR-TEM. Catalytic hydrogenation of CO2 performed in the presence of THF/H2O solvent mixture and KOH resulted in a TON of 533 and 1.6 mmol formate yield. Though C10 could hydrogenate CO2 to formate it was forming nanoparticles during the hydrogenation process. Since nanoparticles were visibly formed during the reaction using C10, this complex was purposely reduced to form N^C^N pincer ligand supported Pd nanoparticles (N^C^N-Pd/NPs), which exhibited excellent CO2 hydrogenation performance in comparison to C10. Hydrogenation of CO2 to formate with N^C^N-Pd/NPs produced the highest TON of 937 with 2.81 mmol formate. Additionally, N^C^N-Pd/NPs were robust and could be reused four times without reducing catalytic activity
