| Abstract: Laurionite-type Pb(OH)I nanorods and rhombic PbI2/TEA hybrid were synthesized by one-step, room temperature, solid-state reaction of lead acetate and potassium iodide in the presence of ethanolamine, diethanolamine and triethanolamine (TEA). The chemical composition, structure and morphology features of products were investigated by XRD, IR, TG, SEM and elemental analyses respectively. The experimental results indicated that ethanolamine, diethanolamine and triethanolamine (TEA) play two important roles during the formation of products. On the one hand, they act as reactants, leading to the formation of Pb(OH)I and PbI2/TEA, on the other hand, they act as soft templates, which induce products to form rods and rhombic structures. |
