The Al-incorporated three-dimensionally ordered macroporous lithium manganese oxide LiAIMnO4dilute hydrochloric acid treatment.The results show that the macroporous diameter and porous wall thickness are240nm and 52nm or so,respectively,and the XRD patterns of samples belong to the pure spinel phase.The Li+aluminum and manganese only has 0.45% and 0.23%,respectively,owing to the substitution of aluminum for theoretical value of HAlMnO4.Meanwhile,the uptake speed of Li+is obviously speeded up,and there is a quite high selectivity for Li+in the solution containing K+,Na+,Ca2+and Mg2+.
