The befitting capping capabilities of AsO4(3-) provide a stable Cu2O nanocatalyst from a galvanic reaction between a Cu(II) precursor salt and As(0) nanoparticles. This stable Cu2O hydrosol appears to be a suitable catalyst for the one-electron transfer reversible redox reaction between Eosin Y and NaBH4. The progress of the reaction relates to three different kinetic stages. In the presence of...

a simple and efficient method for the synthesis of quinolines and polycyclic quinolines using li+ modified nanoporous na+-montmorillonite is described. this new nanocatalyst proceeds via friedlander annulation under solvent-free conditions. it describes our observations about a trend of catalytic activity of lithium cation in nanoporous na+-montmorillonite. in this study, several types of 1,3-d...

Sulfuric acid functionalized magnetic nanocatalyst (SAMNC) has been prepared as an efficientacidic and applied in the one-pot preparation of 2,3-dihydroquinazolin-4 (1H) -one derivatives.This catalyst has been characterized by FT-IR, SEM, and VSM. According to the obtainedresults, including time, yield and recyclability, SAMNC could be considered as an efficient catalystfor organic transformati...

In this study, a novel and environmentally benign o-phenylendiamine stabilized on silica-coated Fe3O4 magnetic nanocatalyst (Fe3O4@SiO2@propyltriethoxysilane@o-phenylendiamine-SO3H/HCl) as a hybrid magnetic organometallic nanocatalyst has been synthesized. After that, the structure of this new catalyst was compl...

The rational design of highly efficient PtNi@ZIF-8 nanocatalyst and the understanding hydrogen generation process for selective complete decomposition hydrazine borane (HB) are disclosed.

n-propylsulfamic acid supported onto magnetic fe3o4 nanoparticles (mnps-psa) was investigated as an efficient and magnetically recoverable catalyst for the one-pot synthesis of substituted coumarins from the reaction of coumarin with variety aromatic aldehydes in high to excellent yield at room temperature under solvent-free conditions. the magnetic nanocatalyst can be readily recovered easily ...
