Layered double hydroxides (LDH) comprise an unusual class of layered materials with positively charged layers and charge balancing anions located in the interlayer region. This is unusual in solid state chemistry: many more families of materials have negatively charged layers and cations in the interlayer spaces (e.g. kaolinite, Al2Si2O5(OH)4).
