摘要：

In this research, a novel core-shell nanostructured magnetic Ti-silica (Mag@MCM-41/TiO2) is synthesized, characterized and its catalytic application is investigated in the production of 1-(alpha-aminoalkyl)-2-naphthols. The Mag@MCM-41/TiO2 was prepared via surfactant directed hydrolysis and co-condensation of tetramethoxysilane (TMOS) around Mag@SiO2 NPs followed by treatment with tetrabutylorthotitanate (Ti((OBu)-Bu-t)(4)). The Mag@MCM-41/TiO2 catalyst was characterized using VSM, FTIR, EDX, SEM, TEM and PXRD. The Mag@MCM-41/TiO2 was applied as an efficient catalyst in the synthesis of 1-(alpha-aminoalkyl)-2-naphthols under ultrasonic conditions at 50 degrees C. This nanocatalyst was recovered and reused for several times under applied conditions. (C) 2019 Elsevier Ltd. All rights reserved.
