TG-DSC results revealed that the decomposition of magnetic CoAl HTLcs proceeded in two stages. The first large endothermic effect below 220℃involves the loss of physically absorbed and interlayer water and the second endothermal effect, between 220℃and 402℃, corresponds to the decomposition of the hydroxide layers and the removal of anions in the brucite-like layers. The S_ and pore diameter information of magnetic CoAl HTLcs were tested by N_2 adsorption-desorption analysis.
