摘要: Abstract A porous ceramic was coated with vertically aligned multi-walled carbon nanotubes (MWCNTs) by spray pyrolysis. Titanium dioxide (TiO2) nanoparticles were then onto this densely MWCNT. The presence of TiO2/MWCNT interfacial arrays confirmed X-ray diffraction (XRD), scanning electron microscope–energy dispersive analysis (SEM–EDAX) and transmission microscope (TEM). This is a novel report in which water loaded most dreadful enterohemorrhagic pathogenic strain Escherichia coli O157:H7 filtered through filter analysed. Bacterial removal performance found to be significantly lower control i.e. plain (P
