Abstract:
Background: Catalysis has been widely applied in pharmaceutical companies in recent
years. This paper reports a useful new approach for the synthesis of pyranopyrazoles.
Objectives: One- pot synthesis of pyranopyrazoles using MgZrO3@Fe2O3@ZnO as a novelcore-
shell nanocatalyst which increases reaction rate, selectivity, ease of work-up and recyclability
of the supports. Method: The present study deals with the synthesis of MgZrO3@Fe2O3@ZnO
core-shell catalyst using the sol-gel method.
Results: The synthesized MgZrO3@Fe2O3@ZnO core-shell nanoparticles were analysed using
XRD, TEM and BET surface area. The nanocatalyst had an average particle size of 20 nm by
TEM images and BET Surface area of 58.93 m2/g.
Conclusion: Novel MgZrO3@Fe2O3@ZnO core-shell nanoparticles have been used as an efficient
and recoverable catalyst for one-pot synthesis of pyranopyrazoles.
