Title:
PRODUCTION OF LAMINAR COMPOUND HAVING INTERLAMINAR CROSSLINKED STRUCTURE
Document Type and Number:
Japanese Patent JP3146351
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for efficiently producing a laminar compd. useful for a highly functional photocatalyst by enlarging the interlaminar distance of the laminar compd. and carrying out interlaminar modification.
SOLUTION: A laminar perovskite type compd. represented by formula K[Ca2 Nan-3NbnO3n+1] [where (n) is an integer of 3-6 and Nb may be substd. at a ratio of ≤10 atom % with at least one kind of a metal selected from among Ni, V, Cu, Cr and W] is treated by a proton exchange, then, long chain alkylamine is intercalated and the resultant compd. is allowed to react with tetraalkoxysilane and fired at 400-600°C in an atmosphere of an oxygen-contg. gas to produce the objective laminar compd. having an interlaminar crosslinked structure.
