Porous NiTiO3 nanorods have been successfully synthesized by an ethylene glycol-mediated route at room temperature followed calcination 600 °C in air. Characterisation results reveal that the obtained are 3 μm length and 400 nm diameter. They possess rough surfaces accumulation holes, which beneficial for adsorption thereby superior photocatalysis. The porous a noticeable optical absorbance visible range, indicating they light photoresponse. photocatalytic activity is evaluated degradation of nitrobenzene, highly toxic organic pollutant wastewaters. exhibit better under irradiation than nanoparticles commercial TiO2 (Degussa P25). enhancement attributed to texture, offers more active sites facilitates mass transport, special 1D structure favors separation photogenerated electron–hole pairs, confirmed surface photovoltage spectra.
