Facile fabrication of porous NiCo2O4 nanosheets with high adsorption performance toward Congo red

In this work, porous NiCo2O4 nanosheets have been fabricated by a facile hydrothermal method. The morphology as well as crystalline structure of products was tested by XRD, FTIR, N2 adsorption-desorption isotherms and TEM. The composite exhibited excellent adsorptive removal capacity toward Congo red (CR), and the maximum adsorption capacity was up to 961.5 mg/g. The best adsorption performance was achieved in the CR solution without adjusting...
