Study on the preparation and photocatalytic oxidation properties of TiO₂/nano-Fe⁰ photocatalysts

Abstract

TiO2/nano-Fe0 composite photocatalysts were prepared via a liquid phase reduction deposition method using anatase nano-TiO2 as a deposition substrate.

Synthesis and photocatalytic properties of three dimensional laminated structure anatase TiO2/nano-Fe0 with exposed (001) facets

“…28,57 In the curve of both the nano-Fe 0 and 3D-TiO 2 /nano-Fe 0 , the characteristic peak at the 2q of 44.64 belonged to a-Fe (110) crystal was observed, suggesting that in the 3D-TiO 2 /nano-Fe 0 composite the nano-Fe 0 keeps its original properties. 53 The crystallite sizes of the 3D-TiO 2 /nano-Fe 0 , 3D-TiO 2 , nano-Fe 0 and nano-TiO 2 were obtained by both SEM images analysis ( Fig. 3 and 4) and Scherrer formula calculation, obtaining average values of 3.5 mm, 3 mm, 80 nm and 10 nm, respectively.…”
