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...

Methyl orange (MO) is a common anionic azo dye that serious harmful pollutant to the environmental aquatic systems, so it must be treated before can discharged. Photocatalysts are usually semiconducting solid oxides create an electron-hole pair by absorbing photons. These electron holes react with molecules on surface of particles. used in water purification, self-cleaning glasses, decompositio...

A green synthesis of Ag/AgCl with an exceptional SPR and photocatalysis property is greatly benefit to the environmental application especially pollutant removal. In this work, a novel plasmonic nanocatalyst using aqueous garlic extract (Allium Sativum L.) was successfully synthesized. The allicin organosulfur compounds in can act as reducing agents process. properties were characterized by sca...

Nano-peanut shell‑OSO3H nanoparticles were simply prepared and characterized by the scanning electron microscopy (SEM), transmission electron microscope (TEM), fourier transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDX), and thermal analysis techniques (TGA/DTG). The catalytic activity of nano-peanut shell‑OSO3H was studied in the synthesis of biological...

In the present study, we report greener, simple, cost effective, non-hazardous and ecofriendly synthesis of silver (Ag) nanoparticles from Alstonia scholaris (L.) R. Br. for first time. The using leaf stock acted as a reducing well capping agent simultaneously. bio-reduced were characterized ultra violet-visible spectroscopy (UV) exhibiting blue shift absorption peak in region 440 nm. newly syn...

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 ...
