From agricultural waste residue to wealth support: A magnetically N-heterocyclic carbene functionalized corn cob cellulose as a new stabilizer for Pd catalyst in Suzuki reaction.

Because of eco-friendliness, biodegradability and ease of modification, cellulose is deemed as alternative to unrenewable petroleum resources. Nonetheless, it is more indispensable to exploit corn cob cellulose produced from agricultural waste residue as supportive materials in green catalysis. In this study, a new magnetically benzimidazole functionalized cellulose/FeO derived from corn cob cellulose as a stabilizer agent (FeO@CL-NHC) was prepared, and palladium was immobilized on this stabilizer (FeO@CL-NHC-Pd).

Schiff base modified starch: A promising biosupport for palladium in Suzuki cross-coupling reactions.

Starch can be used in diverse fields because it is a readily available, non-toxic polysaccharide with adaptable functionality and biodegradability. In this study, taking the aforementioned characteristics into consideration, we designed a modified starch (Starch-SB), which serves as supporting material for palladium stabilization. This new air and moisture-stable robust palladium composite [Starch-SB-Pd(II)] was characterized by FT-IR, XRD, TGA, XPS, SEM, EDX, TEM, CP/MAS C NMR, and ICP-MS analytical techniques.
