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.

TG-DSC结果表明磁性CoAl水滑石有两个过程，在220℃以下的第一个失重过程是由于物理吸附水的移除造成的，在220℃至402℃之间的主要失重过程是由于材料脱除结构水，碳酸根离子和部分羟基造成，并伴随着层板结构的塌陷。N_2 adsorption-desorption测试分析了磁性钴铝水滑石的比表面积、孔径等信息。
