NiAl layered double hydroxides (LDHs) are promising bifunctional catalysts comprising tunable redox and Lewis acidic sites. However, most studies of LDH employ alkali hydroxide carbonate precipitants which may contaminate the final catalyst leach into reaction media. Here, we report an alkali-free route to prepare NixAl LDHs with a composition range x = 1.7 4.1 using (NH4)2CO3 NH4OH as precipit...

Layered double hydroxides (LDH) are interesting materials due to their high absorption and catalytic properties. Their applications in environment, agriculture pharmaceutical fields becoming widely important. The interlayer intralayer cation ordering on layered of Mg:Al 2:1 Zn:Al studied by means different models at Density Functional Theory level. LDH is for monitoring the synthesis these soli...
