Delaminated sodium nonatitanate and a method for producing delaminated sodium nonatitanate

摘要

A hydrothermal synthesis method of making a delaminated titanate is disclosed. The delaminated titanate has a unique structure or morphology. The delaminated titanate is first formed by forming at a low temperature a layered sodium nonatitanate (SNT), which may be referred to as layered sodium titanate. The layered SNT has a unique morphology. The layered SNT is then synthesized into a delaminated titanate having a unique morphology.

主权项

1. A hydrothermal synthesis method, comprising:
mixing sodium hydroxide and a titanium compound to form a slurry; heating the slurry to form a layered sodium titanate having between about 15% and 30% vacancy in the titanium sites; adding an acid to the layered sodium titanate to form a layered acid titanate; and adding a hydroxide of an alkyl ammonium or alkyl phosphonium to the layered acid titanate to form a delaminated titanate consisting of titanate layers; wherein each layer of the layered sodium titanate has an aspect ratio of between 1:5 and 1:15.
