LAYERED TITANIC ACID,LAMELLAR TITANIC ACID,LAMELLAR TITANIUM OXIDE AND METHOD FOR PRODUCING LAMELLAR TITANIC ACID |
摘要 |
A layered titanic acid, characterized in that it is produced by a method comprising subjecting a layered titanate represented by a general formula: A<sb>x</sb>M<sb>y </sb>□<sb> z</sb>Ti<sb>2−(y+z)</sb>O<sb>4</sb>, wherein A and M represent metals having a valence of 1 to 3 and being different from each other, □ represents a defect to be occupied by titanium, x is a positive and real number satisfying 0 < x < 1.0, y and z are positive and real numbers satisfying 0 < y + z < 1.0, to an acid treatment, to thereby substitute hydrogen ions or hydronium ions for 40 to 99 % of A and/or M ions; a lamellar titanic acid, characterized in that it is produced by a method comprising reacting the layered titanic acid with a basic compound, to thereby delaminate the layered titanic acid; and a lamellar titanium oxide, characterized in that it is produced by a method comprising subjecting the lamellar titanic acid to a heat treatment or the like.
