In addition, they conduct a theoretical investigation on the notable impacts of GO defects and oxygencontaining functional groups on the efficacy of its adsorption of organic dyes. A one-step hydrothermal method created new NiFe2O4/MWCNTs hybrids with varying MWCNT content. These hybrids are magnetically recyclable and were used to examine the photocatalytic activity of NiFe2O4/MWCNTs hybrids by Zhu, H-Y. et al.
