Electrospun nanofibers of TiO2/CdS heteroarchitectures with enhanced photocatalytic activity by visible light

Enhanced photocatalytic and photoelectrochemical properties of TiO2 nanorod arrays sensitized with CdS nanoplates

“…Moreover, the absorption edges display a slight red shift. This could result from increased particle size and broadened distribution of CdS NPLs [27][28][29]. As absorption of visible light is essential to photocatalytic activity, the sensitization of the NRAs may be expected to enhance photocatalytic activity.…”

Thermal decomposition approach for the synthesis of CdS–TiO2 nanocomposites and their catalytic activity towards degradation of rhodamine B and reduction of Cr(VI)

“…16 (a)). The photocatalytic degradation of rhodamine B by different photocatalysts under visible light irradiation follows first-order kinetics with respect to the concentration of rhodamine B [55]; the plot of À ln(C t /C 0 ) versus time yields a straight line with slope k (Fig. 16(b)) where C t and C 0 are the rhodamine B concentrations at time t¼ t and t¼ 0, respectively and k is the rate constant.…”

Direct in situ activation of Ag0 nanoparticles in synthesis of Ag/TiO2 and its photoactivity

“…The intensity of the PL spectra of the parent TiO 2 catalysts decreased considerably with the addition of Ag, reflecting the enhanced charge pair separation that led to the increased photoactivity of the catalysts (Fig. 5) [51]. However, sometimes this phenomenon seems to be incompatible, wherein further addition of Ag 0 may act as a recombination center that is detrimental to the photocatalytic activity [40].…”
