Heterogenized palladium chitosan complexes as potential catalysts in oxidation reactions: study of the structure

Catalytic palladium nanoparticles supported on nanoscale MOFs: a highly active catalyst for Suzuki–Miyaura cross-coupling reaction

“…This confirms the bridging mode of the carboxylate group in the compound. The vibration frequency of PdeO bond was reported in the region of 400e650 cm À1 , 35 however, no absorption peaks within this region are observed for Pd-ScBTC NMOFs (see the insetted figure in Fig. 6), implying that ScBTC NMOFs act as solid solvent to support and disperse Pd NPs via electrostatic interaction rather than the direct PdeO covalent bonding.…”

Highly porous chitosan microspheres supported palladium catalyst for coupling reactions in organic and aqueous solutions

“…Chitosan is an inexpensive biodegradable and biocompatible biopolymer comprising of glucosamine and N-acetyl glucosamine from the alkaline deacetylation of natural chitin, which is the second most abundant polysaccharide in nature and is generally obtained from crustacean shells, produced in the order of 10 11 metric tons annually [7,8]. Chitosan has been fabricated into various forms such as flakes, gel beads and fibers, but these forms have relatively low specific surface area [9,10].…”

Complete dechlorination of pentachlorophenol using palladized bacterial cellulose in a rotating catalyst contact reactor

“…Hydrodechlorination of chlorophenols using supported palladium has been reported profusely in the literature [14][15][16][17][18][19]. Various types of support materials such as carbon, chitin, chitosan, amino acids, alumina, silica, zeolites, and metal oxides such as TiO 2 , MgO, ZrO 2 have been used for the immobilization of palladium [14,18,20]. Some of the commercially available immobilized palladium catalysts are: Pd/C and Pdalumina.…”
