Facile preparation of nickel-poor layered double hydroxides from mechanochemically pretreated gibbsite with a variety of interlamellar anions and their use as catalyst precursors for CO2 hydrogenation

Synthesis of NiFe layered double hydroxides with varied layer charge densities: the templating effect of dioctyl sulfosuccinate

“…17,18 LDHs with x values smaller than 0.20 or larger than 0.33 have scarcely been reported. Examples are M 2+ Al-LDHs (M 2+ = Mg, Ni, Co, Zn, and Cu) with x > 0.33 [19][20][21][22][23][24][25][26] and MgAlcarbonate-, 10 -nitrate-, 27 -benzoate-, 28 -terephthalate-, 28 and -deoxycholate-LDHs, 29 MgGa-carbonate-LDH, 11,30 MgFe-chloride-, 31 and -carbonate-LDHs, 32 NiAl-carbonate-LDH, 33 and NiFe-carbonate-LDH with x < 0.20. 33 The study on the extended x has been limited and the successful preparation of a single phase LDH with x < 0.20 or x > 0.33 has not been reported so far.…”
