“…Although the catalyst showed the satisfactory reactivity, it was difficult to recover. Thus, Pd catalysts anchored on heterogeneous solid support materials such as MCM-41 [ 29 ], alumina [ 30 ], silica [ 31 ], carbon nanotubes [ 32 ], microporous polymers [ 33 ], SBA-15 [ 34 ], or some dendrimers [ 35 ] were preferred to develop a ligandless and recyclable catalyst system. However, to the best of our knowledge, only a few of supported Pd catalysts were used in mechanochemically assisted coupling reactions because of the low mechanical strength of the catalysts, the active component of which is easy to leach and deactivate under HSBM conditions.…”

In this paper, the synthesis of a cheap, reusable and ligand-free Pd catalyst supported on MgAl layered double hydroxides (Pd/MgAl-LDHs) by co-precipitation and reduction methods is described. The catalyst was used in Heck reactions under high-speed ball milling (HSBM) conditions at room temperature. The effects of milling-ball size, milling-ball filling degree, reaction time, rotation speed and grinding auxiliary category, which would influence the yields of mechanochemical Heck reactions, were investigated in detail. The characterization results of XRD, ICP–MS and XPS suggest that Pd/MgAl-LDHs have excellent textural properties with zero-valence Pd on its layers. The reaction results indicate that the catalyst could be utilized in HSBM systems to afford a wide range of Heck coupling products in satisfactory yields. Furthermore, this catalyst could be easily recovered and reused for at least ﬁve times without signiﬁcant loss of catalytic activity.

Supported metal nanoparticles hold great promise in heterogeneous catalysis as active and reusable catalysts for various organic transformations. Preparation methods of metal nanoparticles with excellent control over size, shape, and morphology on supports has significantly advanced to improve the performances of the resulting catalysts. Here, we aim to discuss the development of supported metal nanoparticles on mesoporous silica SBA‐15 in the presence of immobilized ionic liquids mostly based on examples from the previously reported results. This review highlights the preparation methods for size‐controlled syntheses and the immobilization of metal nanoparticles on solid supports, especially SBA‐15 by various techniques.

“…[9,10] Among various materials, mesoporous materials may be excellent candidates due to their unique architecture. [15][16][17][18][19][20] Liquid-liquid biphasic catalysis has been widely studied, provided that the catalyst and the reaction product are in two different liquid phases at the end of the transformation. [11][12][13][14] More specifically, recent research indicates that template-containing mesoporous silica is an interesting composite for various applications.…”

An efficient and reusable pH-responsive mesoporous silica nanocomposite shuttle-supported palladium catalyst was synthesized, which efficiently promotes the Sonogashira reaction in water-based biphasic systems. This catalyst of shell-embedded palladium nanoparticles is highly dispersed in organic phase in a pH range from 9 to 10 just like a homogeneous catalyst, and can be separated and reused like a heterogeneous one by adjusting the pH value of the aqueous medium. In addition, Sonogashira reactions can be performed without a copper co-catalyst.
