| Abstract: | A
single-step organic-free process has been evolved to prepare phosphate-modified
titania, a nanomaterial, from titanium oxysulphate solution. The adsorption of
phosphate ions from aqueous solution onto titania has been studied by XRD, XPS,
and DRIFT which show strong adsorption of phosphate, as Ti-O-P on the surface
of titania. An increase in crystallinity and decrease in surface area are
observed with calcination temperature. XPS results reveal a pentavalent
oxidation state for P and the substitution of P for oxygen. The
phosphate-modified titania displays good thermal stability, an essential
property required for the application as catalyst and active support. |
