Solution processing of ruthenium (Ru+) doped ZnO nanoparticles on surface of calcium aluminum silicate beads were carried out under solvothermal conditions (T, 150oC; P, autogenous; duration, 4h). The reagent grade ZnO, ruthenium and calcium aluminum silicate beads (CASB) material were used as starting materials along with methanol as a solvent and thus obtained ruthenium doped ZnO coated calcium aluminum silicate beads were characterized by using X-ray diffraction, SEM, Fourier transform infrared spectroscopy and UV spectroscopy. Solar light mediated Photocatalytic degradation of organic dyes such as brilliant yellow, brilliant blue, rhodamine b and proclor red Mx-5B dye, two mixed dye (rhodamine b and proclor red Mx-5B) and three mixed dye (brilliant blue, brilliant yellow and rhodamine b ) were studied using solvothermal prepared Ru+ doped ZnO coated calcium aluminum silicate beads. The effect of various parameters such as initial dye concentration and Catalyst loading with time duration on photodegradation of organic dyes was investigated.
