Calcined and organo-modified Zn-Al layered double hydroxides (LDHs) were studied as adsorbents and photocatalysts for removal of cationic dye, as namely methylene blue (MB). Zn-Al LDHs with a cationic ratio of 2:4 were obtained by the coprecipitation method. As-synthesized samples were calcined at different temperatures and the phase transformations were investigated by XRD, TG/DTG, and UV-vis-...

Layered double hydroxide (LDH) is an anionic clay material known to be effective as a catalyst for the photodegradation of dye organic pollutants. Zn/Al LDH was synthesized by coprecipitation then impregnated with metal oxides and calcined at 300oC form Zn/Al-TiO2 Zn/Al-ZnO catalysts congo red (CR). The characterization after preparation using SEM UV-DRS while that have been used in 5 regenerat...

in this research a cu-zn-al alloy is produced by melting the raw materials in an electric resistance furnace and then pouring it into a steel mould. the optimum way to achieve the final analysis in the hypo-eutectoid range is determined and the influence of the alloying element, ti on the grain size and the shape memory properties of the samples are investigated. solution treatment (done at 850...
