Layered double hydroxides (LDHs) synthesized by conventional methods are usually hexagonal platelet morphology. Using chitosan as template for synthesis of Ni-Al-CO3 LDHs, the LDH particles are curved in the a direction, deviating from the flat platelets. The crystallite growth in a and c directions is both inhibited. Especially in the c direction, the stacking thickness of LDH sheets decreases to half of the thickness of sample synthesized by conventional method.
