Volume 6, Issue 1, pp. 1-108, Serial No. 18 , January 2018, , Pages 62-69

Abstract
  ZrOCl2.8H2O@nano SiO2 has been synthesized for the first time via a simple procedure and characterized by SEM (scanning electron microscopy), FT-IR, and EDX (energy-dispersive X-ray) techniques. The efficiency of the prepared nanostructure has been explored for the synthesis of benzimidazoles via the ...  Read More
