Synopsis

Layered double hydroxides (LDHs) have a layered structure with a host layer of octahedrally coupled metal cations and a guest layer (interlayer) of anions, which have recently been actively explored for their anion exchange capabilities. In this study, we used an anion exchange method to synthesize a LDH based on zinc and chrome ZnCr-CO3 (Zn0.6 Cr0.4(OH)2(CO3)0.2.nH2O) with different anions to deal with the exchange whereas the use of infrared spectroscopy and X-ray diffraction was essential to characterise, confirm the stability into LDH interlayers and the success of the anion exchange.
