Abstract

Hydrotalcite-like compounds (HTLC) with different cationic ratios (Mg/AI) and charge-balancing inter layer anions were prepared and characterized. The surface areas of HTLCs were found to increase with increasing Mg/AI ratio. Pure HTLCs were obtained when the Mg/AI ratio was below 7. Water adsorption properties of HTLCs show that they are microporous. BET surface areas with water and nitrogen are dependent on the Mg/AI ratio of HTLC. Tungstatepillared HTLC (synthesized from Mg/AI=7) was prepared and characterized, resulting in higher gallery height and surface area.
