Visibly clear : A family of visible‐light‐responsive MCr–layered double hydroxides (LDHs; M=Cu, Ni, Zn) were synthesized. These show remarkable photocatalytic activity with visible‐light irradiation. Experimental and computational studies revealed that the visible‐light response of MCrNO 3 –LDHs originates from a d–d transition in the orderly dispersed CrO 6 octahedra in the hydrotalcite layer.
