| Abstract: | The nanopowders of Mg-Al carbonate layered double hydroxides (MgAl-LDH) were prepared via coprecipitation process. ZnO nanoparticles were homogeneously coated on the ceramic MgAl-LDH surface. After calcination at 500 ℃ for 4 h, X-ray diffraction and scanning electron microscopy were employed to investigate the crystal structure and morphology, respectively. It was demonstrated that ZnO nanoparticles were successfully prepared on ceramic MgAl-LDH support. The obtained nano-ZnO photocatalyst showed a high pho-tocatalytic degradation of malachite green. The enhanced photocatalytic property can be attributed to both high photocatalytic activity of ZnO and good adsorption behavior of ceramic MgAl-LDH, in which the aky structure of MgAl-LDH plays an important role. |
