Photocatalytic activity of poly(3-hexylthiophene)/titanium dioxide composites for degrading methyl orange

Highly efficient photocatalytic degradation of methylene blue by P2ABSA-modified TiO2 nanocomposite due to the photosensitization synergetic effect of TiO2 and P2ABSA

“…7b, the kinetics plots show an apparent rst-order linear form (Àln(C/C 0 ) ¼ k app t). 32 The activities of TiO 2 and the modied photocatalysts were evaluated by comparing the apparent rst-order rate constants (k app ) listed in Table 1. TiO 2 and P/T(2/1) nanocomposites exhibited apparent rate constants of 0.0021 min À1 and 0.0138 min À1 , respectively, showing that P/T(2/1) enhanced the photocatalytic activity.…”

Study on stability of poly(3-hexylthiophene)/titanium dioxide composites as a visible light photocatalyst

“…Conjugated polymer/TiO 2 photocatalysts hold great promise for solar chemical conversion processes by combining the advantages from both the conjugated polymer and the inorganic semiconductor, overcoming the serious drawbacks of fast charge recombination and the limited visible light absorption of inorganic semiconductor. Polythiophenes [8][9][10], polypyrroles [11][12][13], polyanilines [14][15][16][17] and their derivates [18][19][20][21][22][23] have been widely incorporated with TiO 2 , resulting in conjugated polymer/TiO 2 photocatalysts with not only efficient visible light activity but also improved ultraviolet light activity by extending the response spectrum of TiO 2 to visible light region and facilitating the separation of photogenerated carriers.…”

“…With higher charge carrier mobility, dissolubility and processability, long-term stability and broad and strong absorption in visible region [28], poly(3-hexylthiophene) (P3HT) has been reported as the effective sensitizer of TiO 2 [9,10,20]. In present study, poly (3-hexylthiophene)/titanium dioxide (P3HT/TiO 2 ) composites, as a representative of conjugated polymer/TiO 2 photocatalysts, were prepared and through comparative analysis of the physical and chemical structure of the composites before and after the photocatalytic reaction, the stability of the composites was systematically evaluated.…”

Conjugated Polymer/Nanocrystal Nanocomposites for Renewable Energy Applications in Photovoltaics and Photocatalysis

“…In the past decade, several kinds of conducting polymers, including polyaniline (PANI), P3HT, polypyrrole (PPy), PEDOT, and others, have been used in the preparation of photocatalysts based on polymer/semiconductor nanocrystal nanocomposites. With suitable energy levels, conducting polymers can sensitize semiconductor nanocrystals to improve the light harvesting efficiency as well as promote effective charge separation to increase the carrier utilization efficiency.…”
