【 摘 要 】

In this paper, we describe a general process for the synthesis of highly crystalline Znâ€�?�Niâ€�?�Al hydrotalcitelike materials. The structure and thermal decomposition of the prepared samples are studied by XRD, FTâ€�?�IR, TGâ€�?�DSC, SEM, TEM and N₂ adsorption/desorption. The morphology of large-sized, porous and hexagonal platelike Znâ€�?�Niâ€�?�Al hydrotalcite is affected by calcination temperature. BET specific surface area and pore volume are observed to increase with increase of the calcination temperature up to 700°C followed by a further decrease with increasing temperature.
