Iron cobalt oxides, such as typical FeCo2O4 and CoFe2O4, are two spinel structured transitional metal oxide materials with excellent electrochemical performance. As the electrodes, they have been widely applied in the current energy storage and conversion processes such as supercapacitors, Lithium-ion batteries and fuel cells. Based on synthesis approaches and controlled conditions, these two m...

Peroxymonosulfate (PMS) activation has gained increasing attention for its water remediation. In this work, carbon nanotube-supported FeCo2O4 nanoparticles (FeCo2O4/CNT) were prepared and showed tremendous potential as a catalyst PMS activation. The synergistic effect between CNT in FeCo2O4/CNT promotes better catalytic performance than individual or FeCo2O4. synthesized could reach 100% phenol...

We report the preparation and characterization of spinel-structured FeCo2O4 nanoparticles for the efficient and selective oxidation of sulfides. The as-prepared FeCo2O4 nanoparticles were characterized by powder X-ray diffraction (PXRD), energy-dispersive X-ray analysis (EDX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). According to TEM images, the size of the...

Peroxymonosulfate (PMS) activation by bimetallic Co/Fe oxides, especially spinel FeCo2O4, is a promising way in decontaminating organic pollutants wastewaters. However, it suffers from low efficiency and the intrinsic catalytic mechanisms are still poorly understood. Therefore, we applied lattice VOs (oxygen vacancies) adjustment strategy to construct octahedral Co(II)–enriched FeCo2O4 quantum ...

Os problemas ambientais das indústrias estão principalmente relacionados com a produção de elevadas vazões águas residuais carregadas compostos orgânicos recalcitrantes, não biodegradáveis. O aprofundamento no conhecimento novas tecnologias, como o foto-Fenton heterogêneo, e busca por novos materiais catalíticos são necessárias para se alcançar métodos tratamento mais eficientes. Nesse sentido,...
