In this study, we present the fabrication and characterization of a porous membrane based on a polyurea network synthesized via sol-gel polymerization, employing polyethylene glycol (PEG) as a porogen. Then, Pd nanoparticles were loaded through wet impregnation and in situ reduction techniques. This approach enables control over pore size and distribution, which is critical for subsequent catalytic applications.
The metal-loaded membranes will be utilized for catalytic applications, particularly in selective hydrogenation reactions such as the phenol-to-cyclohexanone reaction. Future work will focus on evaluating performance, with an emphasis on activity, selectivity, and reusability in both batch and flow-through modes.
This work demonstrates a versatile platform for the design of functional porous membranes with embedded catalytic sites, which can be tailored for advanced applications in green chemistry and energy-related processes.
