Layered metal oxides containing interlayer oxides and their synthesis
摘要:
A layered product comprises a layered metal oxide and pillars of an oxide of at least one element selected from Groups IB, IIB, IIIA, IIIB, IVA, IVB, VA, VB, VIA, VIIA and VIIIA of the Periodic Table of the Elements separating the layers of the metal oxide. Each layer of the metal oxide has the general formula[M.sub.x .quadrature..sub.y Z.sub.2-(x+y) O.sub.4 ].sup.q-wherein M is at least one metal of valence n wherein n is an integer between 0 and 7, .quadrature. represents a vacancy site, Z is a tetravalent metal, and whereinq=4y-x(n-4)O
