3D hierarchical honeycomb structured MWCNTs coupled with CoMnAl–LDO: fabrication and application for ultrafast catalytic degradation of bisphenol A
2015
3D hierarchical honeycomb nano-structured o-MWCNTs coupled with CoMnAl-layer double oxides have been successfully fabricated and characterized as a heterogeneous catalyst for bisphenol A (BPA) degradation using potassium monopersulfate (PMS) as oxidant. The role of MWCNTs was investigated and discussed in terms of surface morphology, structure, composition and catalytic activity of the as-prepared nanohybrid by investigation of SEM, TEM, XRD, XPS, and Raman measurements, etc. The results showed that catalytic performance of the CNTs–LDO can be significantly enhanced with the increase of o-MWCNTs content in the hybrids, and MWCNTs provided orientation/confinement for nanohybrid formation and the defects generated by calcination might increase PMS activation for the production of sulfate radicals.
