Title : Maximizing catalytic efficiency: Nano palladium integration with hetero calixarenes for future solutions
Abstract:
This study explores the innovative integration of mesomodified hydroxycalix[4]pyrrole derivatives (OHCP) with palladium nanoparticles (PdNPs) to develop a highly efficient nanocatalyst for future catalytic solutions. The OHCP-PdNPs demonstrated exceptional performance in C–C coupling reactions, with stability and pH effects playing a pivotal role in optimizing their catalytic efficiency. The electron-rich hydrazide functional group and the unique four-pyrrole unit structure of the OHCP ligand enabled effective reduction and encapsulation of metal ions, surpassing the capabilities of conventional hydrazine. This led to a robust web-like coating effect around the PdNPs, enhancing their stability in water and air. The encapsulation process significantly improved the activity and selectivity of the PdNPs, facilitating cost-effective production of stable and versatile nanocatalysts. Our findings underline the transformative potential of OHCP-encapsulated PdNPs in advancing efficient catalytic processes, offering sustainable and scalable solutions for future applications in nanotechnology and green chemistry.
