Immobilizing biogenically synthesized palladium nanoparticles on cellulose support as a green and sustainable dip catalyst for cross-coupling reaction

Green Synthesis of Pd Nanoparticles for Sustainable and Environmentally Benign Processes

“…In 2020, Patil and co-workers reported the preparation of a Pd@cellulose fiber from a waste banana pseudostem [109]. Pd nanoparticles, that were biogenically prepared from a banana pseudostem extract, were immobilized on cellulose fibers from waste banana pseudostem.…”

Novel cellulose supported 1,2-bis(4-aminophenylthio)ethane Ni(ii) complex (NiII(BAPTE)(NO3)2-Cell) as an efficient nanocatalyst for the synthesis of spirooxindole derivatives

“…4,5 Homogeneous catalysts have better performance than heterogeneous catalysts due to their better dispersion and co-phase with the reaction mixture, but the problem with their use is that it is difficult and almost impossible to separate them from the reaction medium and reuse them. [6][7][8][9][10] Immobilizing homogeneous catalysts on various supports, such as carbon, 11 silica, 12,13 metal oxide, 14,15 polymer, [16][17][18] and nanocomposites, [19][20][21] is one of the efficient ways to overcome this problem. Carbon-based materials, due to their unique properties such as light weight, many varieties of forms, doping capability with hetero atoms, low-cost and ease of processability, are suitable supports for heterogeneous catalysts.…”

Highly dispersed palladium nanoparticles supported on graphitic carbon nitride for selective hydrogenation of nitro compounds and Ullmann coupling reaction

“…[ 6 ] To prevent the aggregation of nanoparticles, several methods were generally used such as capping the NPs with different capping agents [ 7 ] or immobilizing the NPs on solid supports. [ 8 ] Generally, metal oxide, [ 9 ] porous compound, [ 10 ] carbon black, [ 11 ] polymer, [ 12 ] cellulose, [ 13 ] metal organic framework (MOF), [ 14 ] and 2D graphene [ 15 ] are extremely used as a support for metal nanoparticles. The presence of heteroatom's in graphene such as nitrogen as electron donor [ 16 ] or boron as electron acceptor [ 17 ] can further modify catalytic property of the 2D graphene.…”
