The distributions of Al 13 and Al m in PAC G with different basicity values possess the similar tendency (Table 1 and Fig. S1). And Al 13 content is the dominant aluminum species in the PAC G2.0 and PAC G2.0.It has been confirmed that the contents of Al 13 and Al m in PAC are positively correlated with the contents of Al b and Al a, respectively (Feng et al., 2006).
