The lattice parameters of takovite-like phases. (a) The a parameter plotted against x for a range of Ni–Al (open circles) and Ni–Fe (filled circles) LDH preparations reported in the literature. The data for Ni–Al LDH phases are from the following references: Brindley & Kikkawa (1979); Carteret et al. (2011); d'Espinose de la Caillerie et al. (1995); Hu & Noréus (2003); Indira et al. (1994); Jinesh et al. (2010); Johnson & Glasser (2003); Kovanda et al. (2009); Pérez-Ramírez et al. (2001); Prevot et al. (2009); Rives et al. (2003); Sato et al. (1988); Tsuji et al. (1993); Vieira et al. (2009); del Arco et al. (1999); Han et al. (2009). (b) The c′ parameter plotted against x for Ni—Al—CO3 (open circles) and Ni—Fe—CO3 (filled circles) LDH phases reported in the literature. The data are from: Brindley & Kikkawa (1979); Carteret et al. (2011); d'Espinose de la Caillerie et al. (1995); Jinesh et al. (2010); Johnson & Glasser (2003); Kovanda et al. (2009); Prevot et al. (2009); Rives et al. (2003); Sato et al. (1988); del Arco et al.
