Synthesis of Cu@CF@SBA15: A Versatile catalysts for (i) reduction of dyes, trifluralin, Synthesis of (ii) DHPMs by Biginelli reaction and (iii) 1,2,3-triazole derivatives by ‘Click reaction’

•Synthesis of magnetically separable Cu nanoparticle loaded CoFe2O4@SBA15 catalysts.•Reduction of various synthetic dyes, trifluralin.•Synthesis of DHPMs via Biginelli reaction pathway in solventless condition.•Synthesis of 1,2,3-triazole derivatives by ‘Click reaction’ in aqueous medium.

Herein, we are reporting a facile route to synthesize magnetically separable Cu nanoparticle loaded CoFe2O4@SBA15 catalysts, which exhibits high catalytic activity towards (i) reduction of various synthetic dyes, trifluralin, (ii) synthesis of DHPMs via Biginelli reaction pathway in solventless condition and (iii) 1,2,3-triazole derivatives by ‘Click reaction’ in aqueous medium. To the best of our knowledge, this is the first time one single catalyst is reported which shows its high activity for these three important reactions.
