Hidroksida Berlapis Ganda ZnCrCI: Kesan Haba Terhadap Luas Perm.ukaan dan Keliangan

ZnCrCI layered double hydroxides, with Zn/Cr ratios (R) 3 and 4 were prepared by a coprecipitation method and heat treated samples were subsequently prepared. Their bulk structure was investigated by X-ray diffraction and surface area techniques. X-ray diffraction analysis showed that the layered d...
