Nano-sphere silica sulfuric acid: novel and efficient catalyst in the one-pot multi-component synthesis

Abstract

In this report, synthesis, characterization and application of nano-sphere silica sulfuric acid as a novel and heterogeneous catalyst for the synthesis of β-acetamido ketone derivatives at room temperature are described. The catalyst has been identified using various techniques (XRD, SEM, TEM, EDX, TGA, FT-IR), and results show that it has a spherical shape and its particle size is between 60 and 90 nm.
