Synthesis and characterization of a supported Pd complex on volcanic pumice laminates textured by cellulose for facilitating Suzuki–Miyaura cross-coupling reactions

Abstract

An efficient natural-based catalyst constructed of volcanic pumice, cellulose polymeric chains, and palladium nanoparticles is presented for Suzuki–Miyaura coupling reaction.

RETRACTED: Multi‐Stimuli Nanocomposite Therapeutic: Docetaxel Targeted Delivery and Synergies in Treatment of Human Breast Cancer Tumor

“…Previously, we have reported several magnetic systems in micro‐ and nanoscale for diverse functional applications. [ 17–24 ] To further expand upon this work, we utilized one of the most commonly employed polymers, polyvinyl alcohol (PVA), to encapsulate magnetic Fe 3 O 4 NPs by virtue of its extended hydrogen bonding and to provide a selective release medium for DXL. [ 25 ] Drug molecules, such as DXL, can be incorporated into a PVA gel when polymer chains are in a shrunk state at low temperatures, and subsequently released in a target tissue upon a PVA transition into a swollen gel at 37 °C.…”

Convenient conversion of hazardous nitrobenzene derivatives to aniline analogues by Ag nanoparticles, stabilized on a naturally magnetic pumice/chitosan substrate

“…29,30 In the case of the VP, the noticeable inherent magnetic property makes it more distinguished from other types of the porous materials applicable for the catalytic aims. 31 As discussed above, inherent magnetic property of the VP provides ultra-affluence in the separation as well as the purication processes. Hence, we decided to continue our previous studies on the VP by using that as an appropriate substrate for metal ion stabilization and further catalytic purposes.…”

Highly porous copper-supported magnetic nanocatalysts: made of volcanic pumice textured by cellulose and applied for the reduction of nitrobenzene derivatives

“…On the other hand, the rest of the hydroxyl functional groups of cellulose, which are free of hydrogen bonds with the hydroxyl functional groups of pumice, are suitable for chelation by cationic metals such as copper and palladium and can form heterogeneous catalytic composites from natural components; this is one of the most important properties of this composite. 28 The synthesized composite is notable even in terms of mechanical properties because it is a stable hybrid structure. 29,30 As mentioned earlier, the synthetic heterogeneous catalytic composite in this work is suitable for scaling up and industrial applications because of its high biocompatibility and because it is made from components found in abundance in nature.…”
