Delaminated sodium nonatitanate and a method for producing delaminated sodium nonatitanate

DWPI Title: Hydrothermal synthesis of delaminated titanate with titanate layers for e.g. photocatalysis involves mixing sodium hydroxide and titanium compound to form slurry, heating, adding acid to form layered acid titanate, and adding hydroxide
Abstract: 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.
Use: Hydrothermal synthesis of delaminated titanate containing titanate layers for photocatalysis and ion-exchange.
Advantage: The delaminated titanate has unique morphology, with improved surface area for applications, such as photocatalysis and ion-exchange.
Novelty: A delaminated titanate containing titanate layers is hydrothermally synthesized by mixing sodium hydroxide and titanium compound to form slurry, heating slurry to form layered sodium titanate having 15-30% vacancy in the titanium sites, adding acid to layered sodium titanate to form layered acid titanate, and adding hydroxide of alkyl ammonium or alkyl phosphonium to layered acid titanate to form, where each layer of layered sodium titanate has aspect ratio of 1:5-1:15.
