A nitrogen ligand, i.e. 1,3-di-(o-aminophenoxy)-2-propyl propargyl ether (DPPE), has been synthesized and characterized. Magnetic mesoporous silica composite (MNP@SiO2-SBA) was obtained via embedding magnetite nano-particles (MNPs) between SBA-15 channels. DPPE palladium dichloride (MNP@SiO2-SBA-DPPE-Pd(II)) then prepared click chemistry fully The Hiyama reaction conditions including solvent, a...

silica gel has been used for synthesis of biscoumarin derivatives starting from 4-hydroxycoumarin and aryl aldehydes. the reaction conditions are completely in agreement with green chemistry principles including sing water as media and a recyclable and safe catalyst. this method is also simple and inexpensive and leads to high yield of products in short reaction times.

Vertically oriented single-walled carbon nanotubes (SWNTs) attract considerable attention, because it is expected as an ideal field emitter that can realize lower threshold voltage and higher electric current than microtips of Si or metals. In this study, we aim that SWNTs are vertically oriented using mesoporous silica film as a guide of the growth for SWNTs. For the orientation, the catalyst ...

The selective hydrogenation of benzofurans in the presence a heterogeneous non-noble metal catalyst is reported. developed optimal catalytic material consists cobalt-cobalt oxide core–shell nanoparticles supported on silica, which has been prepared by immobilization and pyrolysis cobalt-DABCO-citric acid complex silica under argon at 800 °C. This novel allows for simple functionalized to 2,3-di...

The combination of first-row transition compounds or nanoparticles in with silica-based supports offers a great possibility for catalyst design. In particular iron, cobalt and nickel-based materials, rise attention due to their availability, low cost interesting reactivity, enabling transformations that are not possible noble metals. Different support strategies exist where mesoporous interest ...
