Abstract: Nanotechnology is a facilitating technology that deals with nanometre sized particles in several fields of science such as Chemistry, Physics,Biotechnology and also in Material science. A heterogeneous, versatile multi metal oxide ZnO-MgO–ZrO2 nano catalyst was prepared by chemical co-precipitation method. The synthesized multimetaloxide nanoparticles were characterized by several analytical techniques such as UV, FT-IR spectroscopy, XRD (X ray Diffraction Studies) and SEM (scanning electron microscope). The UV−visible absorption spectrum showed a characteristic optical absorption peak of ZnO-MgO–ZrO2 nano catalyst at 260 nm. The X-ray diffraction pattern suggested the formation and crystallinity of ZnO-MgO–ZrO2 NPs. Spherical ZnO-MgO–ZrO2 NPs synthesized with an average particle size of 26 nm were confirmed by scanning electron microscopy. Photo catalytic degradation was also investigated with crystal violet dye under UV-irradiation source
