ZnAlLa-CO3 layered double hydroxides （LDHs） with different Zn/Al/La molar ratios were prepared by the constant pH coprecipi- tation method. The synthetic materials were characterized by X-ray diffraction （XRD）, Fourier transform infrared spectroscopy （FTIR）, scan- ning electron microscopy （SEM）, Bru...
