ABSTRACT
In this chapter we present an overview of what we regard as the most significant areas of recent activity in layered double hydroxide chemistry, using documents known to us through mid-2002, with occasional later examples. While we have attempted to give credit to the initiators in each area, we make no claims to ascribing priority (itself an uncertain matter in a fast-moving field) and will no doubt have overlooked many seminal papers; for this we can only ask our colleagues for their understanding. The division into sections and subsections is, we hope, self-explanatory. Significant results can of course have implications in more than one area, and we have therefore attempted to reduce duplication by cross-referencing.
