The increase in demand for Pd and its low abundance pose a significant threat to future availability, rendering research into more sustainable Pd-based technologies essential. Herein, we report scavenging mechanically robust hybrid gel beads composed of agarose, polymer gelator (PG), an active low-molecular-weight (LMWG) based on 1,3:2,4-dibenzylidenesorbitol (DBS), DBS-CONHNH2 . robustness the PG ability LMWG reduce Pd(II) situ generate naked Pd(0) nanoparticles (PdNPs) combine within these give them potential as practical catalysts Suzuki-Miyaura cross-coupling reactions. optimized demonstrate good reusability, green metrics, most importantly sustain stirring, improving reaction times energy consumption compared previous examples. In contrast reports, leaching palladium from next-generation is almost completely eliminated. Additionally, first time, detailed investigation Pd-loaded explains precisely how are formed without stabilizing ligand. Further, catalytic investigations that catalysis occurs beads. Hence, can essentially be considered "nonligated" heterogeneous PdNP catalysts. Given challenges developing ligand-free, stable catalysts, may have development easily used systems perform chemical reactions "kit" form.
