the influence of cu doped zro2 catalyst for the modification of the rate of a photoreaction and forming microorganism resistance

Pure and copper-doped zirconium oxide nanoparticles were synthesized using a co-precipitation processand investigated the effect of doping on photocatalytic and anti-microbial activities. the prepared samplesare pure tetragonal phase, as shown by the x-ray diffraction pattern, and the crystallite size decreasesas the dopant concentration increases. higher dopant concentrations resulted in needle-shapedmorphology, as seen in the sem image. the presence of zr, cu, and o in the sample is confirmed by edsanalysis. according to uv-vis analysis, when the cu content is increased, a more significant wavelengthabsorption band edge is formed, and the band gap reduces with the increase in dopant concentration.all samples have magnetic hysteresis loops with diamagnetic background effects, according to vsm tests.a prominent and influential peak at 485nm in the pl spectra suggests that zro2 nanoparticles emit bluelight. the produced nanoparticles were utilized as a photocatalyst to degrade methylene blue (mb) dye,and the results indicate that a high dopant concentration (0.08wt percent) outperforms pure and otherdopant concentrations. copper-doped zro2 has moderate anti-bacterial and anti-fungal activities.
