The crystal structure, morphology, size, and elemental composition of ZrO2 nanorods were determined using XRD, SEM, EDX analysis. The optical properties and photocatalysis were analyzed using UV-Vis spectroscopy. The investigation of XRD pattern indicates tetragonal (t-ZrO2) and monoclinic phases (m-ZrO2) for the annealing temperatures 500 and 900 ◦C respectively. SEM images depicts rod like morphology. UV-Vis spectra illustrates that the synthesized samples have wide band gap. t-ZrO2 photocatalyst degrades methylene blue dye with 80 % removal efficiency in 180 minutes.</p></abstract><kwd-group xml:lang="en"><kwd>zirconium oxide (ZrO2)</kwd><kwd>co-precipitation</kwd><kwd>photocatalysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mahy J.G., Lambert S.D., et al.
