Herein we have identified an optimal catalyst, Pd1Ag1.7, for the tandem reductive amination between nitroarenes and aldehydes (selectivity > 93%). Key to the success is the ability to control the compositions of the investigational Pd1-xAgx (x = 0-1) catalysts, as well as the clear composition dependent activity/selectivity trend observed in this study. This catalyst features a wide substrate s...

nanostructured ruo2 powders were synthesized via a hydrothermal method at 180 °c for 12 h using 1 and 2 m naoh aqueous solutions. the structure of the obtained nanomaterials was investigated by powder x-ray diffraction (pxrd) technique. the morphology the obtained materials were studied by field emission scanning electron microscope (fesem). the technique showed that with changing the reaction ...

   This procedure has developed the use of TiO2 nanoparticles as an environmentally friendly and highly efficient heterogenous nanocatalyst for the eco-safe, facile and one-pot three-component Biginelli synthesis of biologically active corresponding 3,4-dihydropyrimidin-2-(1H)-one/thione derivatives under solvent-free conditions. This eco-friendly protocol provi...

a series of copper and cobalt substituted nanospinel ferrites have been synthesized by the hydrothermal method. these compounds were characterized by ft-ir, xrd, edx, sem and vsm techniques. all of the synthesized nanospinel ferrites were found to be highly efficient and magnetically recoverable in the solvent-free synthesis of substituted 2,6-(2-hydroxybenzyl)-phenols (trisphenols). a wide ran...

Global warming persuades researchers to improve the effectiveness of renewable energy technologies, such as H2 production by methane steam reforming (MSR) an endothermic process. Herein, a nanocatalyst based on open-cell nickel foam 40 (pore per inch) with high thermal conductivity was prepared. The synthesized chemical stepwise synthesis approach, pre-treatment, pulsed electrocodeposition Ni-A...

<p>In this research, we have described a facile and user-friendly protocol for the formation of 2((1H-Indole-3yl)(Phenyl)methyl)malononitrile derivatives using recoverable efficient TiO2 nanocatalyst. This is simple incredibly synthesis novel derivatives. Nanoscale used as catalyst. Since TiO<sub>2 </sub>has more surface area easily binds with active site reactive molecule ini...
