SÍNTESE DE NANOPARTÍCULAS MAGNÉTICAS DE CuFe2O4 POR TERMODECOMPOSIÇÃO DE 8-HIDROXIQUINOLINATOS, SUPORTADAS EM PASTILHAS DE VIDROS RECICLADOS E SUA APLICAÇÃO EM CATÁLISE

Abstract

In the present work, a new synthetic approach for the production of copper ferrite is presented through the thermodecomposition of copper II and iron III chelates, synthesized simultaneously with 8-Hydroxyquinoline. The chelates were previously labeled using techniques such as XRD, FTIR, FRX, SEM, EDS. Next, a detailed thermal study of the chelates was carried out, using TGA, DTG and DTA in oxygen and nitrogen atmospheres, with different heating rates. Subsequently, the chelate was sent to calcination at 1050 ºC, resulting in CuFe2O4 in powder form. Ferrite was proven by XRD, SEM, TEM, EDS, MAV. After characterization, the powder was supported on recycled glass tablets, which were tested by XRF, SEM, EDS and MAV. The tablets produced were evaluated as future prospects in describing reactions for the production of tetrazole and perimidine, which were characterized by NMR. Another aspect evaluated was the recyclability of the synthesized tablets, in addition to the study of their duality, since in the occurrence of perimidine the tablets simultaneously played the role of development and magnetic bar. This integrated approach enabled exploration of both the overview and catalytic potential of copper ferrite supported on recycled glass, contributing to a comprehensive understanding of the properties and applications of this material.
