| description | <p>In the recent years nanosize layered double hydroxide materials have been extensively prepared and studied for many future applications. In this contribution, Zn-Al-PAB layered double hydroxide (PAB=para amino benzoate) with wide range particle size and various shape is reported. Para amino benzoate acid is one of the sunscreen compounds. Zn-Al-PAB with particle size in the range of 100-200 nm and spherical shape can be prepared using reactants of zinc chloride, aluminium chloride and sodium para amino benzoate. Zn-Al-PAB that has larger particle size of 300-500 nm with cubic shape is obtained when zinc nitrate and aluminium nitrate are used. If zinc sulphate and aluminium sulphate are used, much larger particle size of 700-900 nm with turbine-like shape is yielded. During the nucleation process, chloride, nitrate and sulphate in the solution help control the shape and size of Zn-Al-PAB LDH. Hydration number of the anions is believed to be responsible for the growth of the Zn-Al-PAB LDH aggregate that will affect the size. Large hydration number of anion will set barrier for Zn-Al-PAB to grow bigger.</p> |
