Focusing on layered compounds at the core of materials intercalation chemistry, this reference comprehensively explores clays and other classes of materials exhibiting the ability to pillar, or establish permanent intracrystalline porosity within layers. It offers an authoritative presentation of their fundamental properties as well as summaries of cutting-edge research results. Outlines modern usages of clays and other layered materials, including catalytic and photocatalytic applications. With chapters that explain basic concepts first before delving into more scientifically complex topics, the Handbook of Layered Materials
