dc.description.abstractZn/Cr layered zinc hydroxide materials with different molar ratios of Cr/Zn have been synthesized through the coprecipitation method at pH of 9.0e9.5. At high Cr/Zn molar ratios of 0.5/1e1/3, the ma-terials possess some layered structure with carbonate anions between the interlayer galleries. The cat-alysts present uniform particle sizes and quite high surface area. An isomorphous substitution of Zn 2þ by Cr 3þ in the brucite-like sheets makes the layered Cr-doped zinc hydroxides acting as catalysts for efficient oxidation of rhodamine B with H2O2solution. The experimental results indicated that the intra-lattice Cr 3þ ions are more active than Cr2O3 components in the oxidative removal of rhodamine B. The degradation efficiency is dependent on the intra lattice Cr 3þ contents and reaction variables. The Cr/Zn LDH gave a high decolorization (99%) of rhodamine B at near neutral pH and room temperature.en_US
