Lattice Matching Growth of Conductive Hierarchical Porous MOF/LDH Heteronanotube Arrays for Highly Efficient Water Oxidation

Adv. Mater. 2021, 33, 2006351 DOI: 10.1002/adma.202006351 According to new synchrotron X-ray powder diffraction data,[1] the chemical composition and crystal structure of Co-LDH (JCPDS Card 48-0083[2]) needs to be corrected in the published article. Its composition, thought to be Co(CO3)0.5(OH)·0.11H2O, should be corrected to Co6(CO3)2(OH)·8H2O. Further, the space group should be corrected to hexagonal P-62m with unit cell parameters of a = b = 10.3236(4) Å, and c = 3.12244(15) Å; and the related crystal planes (100), (110), (021), (002), (300) and (311) should be corrected to (010), ( 1 ¯ 20 ), ( 1 ¯ 30 ), (001), (011) and ( 1 ¯ 31 ). The reflections observed for the crystalline components of the reported material, as shown in Figure 2a (and in Figure S2–S4, Supporting Information) of the published article, may correspond to Co-LDH and consequently also to isostructural CoNiFe-LDH and cMOF/LDH-48.
