“…These results are also in the good agreement with Zhu et al [55]. They observed that the degradation behavior of RhB under Vis illumination in the presence of Pt/CdS-TiO 2 nanotube arrays was remarkably improved when disodium ethylenediaminetetraacetate (EDTA, 2 mM), the hole scavenger, was added.…”

“…Because CdS suffers from photocorrosion, it is very often used to sensitize wide band gap semiconductors, transferring electrons under visible light illumination to their conduction band (compare Fig. 3), and their combination is still a very active topic in photocatalysis and photoelectrochemistry, especially in combination with TiO 2 nanowires and nanotubes [34,35]. For better charge extraction, CdS has also been combined with graphene or rGO [36][37][38][39], ZnO [40,41], and recently with numerous other semiconductors such as Nb 2 O 5 [42], Cu 2 S [43], Bi 2 S 3 (forming a type I heterojunction) [44], γ-TaON [45], and other II-VI semiconductors such as ZnSe [46] or CdTe [47].…”

Combining different light-absorbing materials for the formation of semiconductor heterojunctions is a very effective strategy for preparing highly active photocatalyst and photoelectrochemical systems. Moreover, the combination of solid state semiconductors with polymers or molecular absorbers expands the possible combinations of materials to alter light absorption and optimize charge carrier separation. In this chapter, different strategies to prepare such composites are presented, highlighting the necessity of intimate interfacial contact for optimum charge carrier transfer. Moreover, the most recent developments and improvements in the formation of heterojunctions and composite photocatalyst systems based on semiconductor solids are presented.

“…The integration of adsorption and photocatalytic treatment mitigates many problems associated with the wastewater industry. This hybrid process can address the limitations of each method when operated separately, which enhances the total removal efficiency of the entire process (Danwittayakul et al 2015, Villa et al 2015, Zhu et al 2015. In 1972, Fujishima and Honda discovered photocatalytic water splitting on a TiO 2 electrode under ultraviolet light (Hashimoto et al 2005;McCullagh et al 2007.…”

AbstractFor the past 40 years, titanium dioxide (TiO2) nanomaterials have attracted immense attention because of their potential applications in the photodegradation of organic pollutants, photocatalytic water splitting for H2 generation, and dye-sensitized solar cells. Despite the fact that the potential applications of TiO2 nanoparticles are ubiquitous, they are not problem free, examples include a large interfacial area that causes slow charge carrier transport, a wide optical band gap that leads to limited applications using solar light, and single-phase and nanoscales features that induce fast recombination of photo-reduced carriers. Therefore, this review highlights the development associated with the adsorption photocatalysis hybrid system for treating wastewater. The immobilization of TiO2 photocatalysts in metal oxide, carbon, and ceramic materials to form TiO2 hybrid systems could prevent the problem of particle recovery, adsorption capacity, and the separation process. Such hybrid systems require significant effort of optimizing the specific surface area-to-volume ratio of the supported photocatalysts with its photocatalytic activities.
