Extended Data Fig. 4: Photographs of cation-exchange intercalation in other 2DACs.
From: A cation-exchange approach to tunable magnetic intercalation superlattices

a, LiMoSe2 and CoxMoSe2 soaked in water. b, LiMoTe2 and CoxMoTe2 soaked in water. c, LiWS2 and CoxWS2 soaked in water. d, LiWSe2 and CoxWSe2 soaked in water. e, LiWTe2 and CoxWTe2 soaked in water. f, LiIn2Se3 and CoxIn2Se3 soaked in water. g, LiSnSe2 and CoxSnSe2 soaked in water. h, LiBi2Se3 and CoxBi2Se3 soaked in water. Li-intercalated materials react strongly with water, causing significant hydrogen bubble formation and rapid exfoliation. In contrast, Co-exchanged materials remain stable in water, indicating their distinct chemical reactivities and visually confirming the successful replacement of Li+ with Co2+.
