Abstract
A series of Cu,Cr-layered double hydroxides of Cu/Cr ratio equal 2 has been synthesized by co-precipitation at a constant pH, using different preparative conditions. The investigated synthesis parameters included: ageing time, speed of reactants addition, temperature of co-precipitation and pH of synthesis. The dominant product of the synthesis was the nitrate form of Cu,Cr-LDH, containing ca. 10 mol% of carbonate. Modifications of experimental conditions affected chiefly the samples crystallinity. The most obvious effects were associated with changing of pH of the co-precipitation, the most acidic conditions providing a material of the best crystallinity. At the medium synthesis temperature (55degreesC), a slow addition of the reactants and a long ageing were favourable, but a significant shortening of the ageing time caused only minor deterioration of the sample crystallinity. The latter finding is of practical importance for an upscaling of the process.
