Description |
Hydrolysis of ZnO in acidic pH provides a facile route for synthesis of layered double hydroxides
(LDH)bearingZn2+withCr3+andAl3+withouthavingcarbonateionintheinter-layer position.The
thermal decomposition of the prepared LDH show that with the increase of Cr3+ content in the
systemthereisanincreaseinthethermalstability ofthecompounds.IncaseofZn–CrLDHthereis
a non-mass loss transition around 420°C. Segregation of parent LDH structure to a bivalent oxide
and a spineltakesplacein both Zn–Cr and Zn–Al LDH only at temperatures above 550°C
