Design and synthesis of Fe3O4@SiO2@KIT-6@DTZ-Pd0 as a new and efficient mesoporous magnetic catalyst in carbon–carbon cross-coupling reactions

Abstract

In this paper, a new type of mesoporous material based on KIT-6 has been introduced. In this aim, magnetic Fe3O4 nanoparticles and mesoporous silica KIT-6 have been combined to obtain mesoporous MNPs. The prepared magnetic mesoporous catalyst has been applied in different carbon–carbon cross-coupling reactions including Mizoroki–Heck, Suzuki–Miyaura, and Stille reactions. This magnetic mesoporous compound is characterized by various techniques including FT-IR, BET, VSM, SEM, XRD, and TGA.

Efficient and biocompatible new palladium-supported boehmite nanoparticles: synthesis, characterization and application in Suzuki–Miura and Mizoroki–Heck coupling reactions

“…35 The peaks in the areas of 39.75, 46.65, 67.85, 82.19 and 87.45 correspond with reection planes 111, 200, 220, 311 and 222 in the XRD pattern and well show that the palladium zero nanoparticles are stabilized on the boehmite substrate (JCPDS card 46-1043). [36][37][38][39][40][41] The presence of these peaks in the catalysts used in Heck and Suzuki reactions shows that the palladium in the sample has maintained its neutrality aer the catalytic activity. Calculating the size of nanoparticles using Scherer's formula shows that the size of nanoparticles is about 13 nm.…”

Palladium Nanoparticles Supported on Porous Silica Materials as Heterogeneous Catalysts of C−C Coupling and Cross‐Coupling Reactions

“…Ghorbani‐Choghamarani and Moradi synthesized a catalyst support by combining KIT‐6, SiO 2 , and magnetic Fe 3 O 4 [89] . Briefly, SiO 2 /Fe 3 O 4 particles were coated with KIT‐6, and then a treatment with diphenylthiocarbazone (DTZ) gave the required support material.…”

Green preparation and characterization of AGC-ZM-2022 as a novel mesoporous silica material using palmitic acid as a natural template

“…[11][12][13][14][15] The main applications of nanoporous materials in chemistry are their use in the manufacture of chemical sensors, and as a surface for the stabilization of chemical and biochemical catalysts. [16][17][18] The development of these materials in the future depends on the manufacture of engineered and controlled porous materials for the intended applications. Zeolites, 19 MOF, 20 microspheres, 21 nanoporous carbon, 14 and silica 22 are the most important nanoporous structures.…”
