| Popis: | Hollow mesoporous silica yolk-shell nanocomposite with a magnetic core has been synthesized and functionalized with 1-methyl-(3-trimethoxysilylpropyl) imidazoliumchloride ionic-liquid. Moreover, WO42- nanoparticles were incorporated into the yolk-shell nanoparticles to prepare pyrazole coumarin in short reaction times and high yield in EtOH/H2O at 70 °C. The mosoporous silica yolk-shell with high surface area, nontoxic, and the outer and inner void layer shows excellent resistance after use in seven cycles. |
