Development of novel and green NiFe2O4/geopolymer nanocatalyst based on bentonite for synthesis of imidazole heterocycles by ultrasonic irradiations

Geopolymers as aluminosilicate inorganic polymers and eco-friendly building materials which can be used as substrate for different kinds of composite. In this research, according to the fabrication of geopolymer based on bentonite as a substrate and embedment of NiFe 2 O 4 nanoparticles in the construction of this polymer, the synthesis of a new magnetic nanocomposite (NiFe 2 O 4 /geopolymer) was investigated for the first time. In order to...
