Abstract

Abstract Organic-swelled layered metal chalcogenides, e.g., titanometallates or silicotitanates, are intercalated with polymeric chalcogenide by plural treatments with hydrolyzable, electrically neutral polymeric chalcogenide precursor, e.g., tetraethylorthosilicate, to provide products of improved surface area.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 60 words
A method for intercalating an organic-swelled layered metal chalcogenide with a polymeric chalcogenide which comprises: (a) providing between the layers of the layered metal chalcogenide an electrically neutral, organic compound capable of conversion to said polymeric chalcogenide by hydrolysis; and converting said compound in the presence of water to the interspathic polymeric chalcogenide and (b) repeating (a) at least once.
Claim 2
Independent Claim 60 words
A method for intercalating an organic-swelled layered metal chalcogenide with a polymeric chalcogenide which comprises: (a) providing between the layers of the layered metal chalcogenide an electrically neutral, organic compound capable of conversion to said polymeric chalcogenide by hydrolysis; and converting said compound in the presence of water to the interspathic polymeric chalcogenide and (b) repeating (a) at least once.
Claim 3
Dependent Claim 10 words
The method of claim 1 wherein (a) is repeated twice.
Claim 4
Dependent Claim 12 words
The method of claim 1 wherein the product of (b) is calcined.
Claim 5
Dependent Claim 24 words
The method of claim 1 wherein said interspathic polymeric chalcogenide is an interspathic polymeric oxide and said layered metal chalcogenide is a layered oxide.
Claim 6
Dependent Claim 15 words
The method of claim 1 wherein said converting is effected by the addition of water.
Claim 7
Dependent Claim 13 words
The method of claim 1 wherein said interspathic polymeric oxide comprises polymeric silica.
