چکیده
|
In this work, metal nanoparticles (fe) doped tio2 nanocomposites as a photocatalyst in an efficient environment for decolorizing dyes have been used as water pollutants. the metal nanoparticles uniformly dispersed in the tio2 matrix have been synthesized successfully by a co-precipitation process using titanium isopropoxide (ttip) and metallic nitrates as precursors and characterized with various techniques (xrd, ftir). the results indicated that the nanocomposite samples obtained by this method had the nanocrystalline pure anatase titanium dioxide phase structure that contains metal nanoparticles and good photocatalyst properties. the results showed that the titanium dioxide matrix was well stabilized and provided a suitable substrate for the placement of metal nanoparticles. the decolorization of methylene blue dye as a water pollutant was investigated in uv light and nanoparticles. the nanocomposite synthesized at ph = 6 and 120 minutes and 0.01 g of adsorbent using methylene blue dye showed photocatalytic properties

Abstract
|
In this work, metal nanoparticles (Fe) doped TiO2 nanocomposites as a photocatalyst in an efficient environment for decolorizing dyes have been used as water pollutants. The metal nanoparticles uniformly dispersed in the TiO2 matrix have been synthesized successfully by a co-precipitation process using titanium isopropoxide (TTIP) and metallic nitrates as precursors and characterized with various techniques (XRD, FTIR). The results indicated that the nanocomposite samples obtained by this method had the nanocrystalline pure anatase titanium dioxide phase structure that contains metal nanoparticles and good photocatalyst properties. The results showed that the titanium dioxide matrix was well stabilized and provided a suitable substrate for the placement of metal nanoparticles. The decolorization of methylene blue dye as a water pollutant was investigated in UV light and nanoparticles. The nanocomposite synthesized at pH = 6 and 120 minutes and 0.01 g of adsorbent using methylene blue dye showed photocatalytic properties
