A facile synthesis of CdSe quantum dots-decorated anatase TiO2 with exposed {0 0 1} facets and its superior photocatalytic activity

Retorting Photocorrosion and Enhanced Charge Carrier Separation at CdSe Nanocapsules by Chemically Synthesized TiO2 Shell for Photocatalytic Hydrogen Fuel Generation

“…The similar broad features of Se3d spectrum were highlighted in recent reports . The peak broadening may be due to several reasons including Se oxidation or Se 2− anionic species interaction with Ti−O lattice (Ti−O−Se).…”

Photo-reduction of bromate in drinking water by metallic Ag and reduced graphene oxide (RGO) jointly modified BiVO4 under visible light irradiation

“…Larger photocurrent indicated a higher electrons and holes separation efficiency (Wang et al, 2016). As illustrated in Fig.…”

“…The PL emission intensity is an indicative of electron-hole separation efficiency, which is often used to explore the charge carrier trapping, migration and transfer (Wang et al, 2016). As seen in Fig.…”

In situ fabrication of a direct Z-scheme photocatalyst by immobilizing CdS quantum dots in the channels of graphene-hybridized and supported mesoporous titanium nanocrystals for high photocatalytic performance under visible light

“…[4][5][6][7] Due to these benets, QDsensitized solar catalysts (QDSSCs) have attracted widespread attention. A plethora of architectures for QDSSCs employing inorganic QDs, such as CdS, 8 CdSe, 9 PbS, 10 InP, 11 PbSe, 12 and InAs, 13 adsorbed onto wide-bandgap semiconducting oxides like ZnO, TiO 2 , and SnO 2 , have hitherto been proposed, and their applicability to visible-light harvesting has been investigated. Among QD materials, CdS has been one of the most representative materials as a stable and efficient photoabsorber because its optical bandgap can be readily tuned from 0.3 to 1.6 eV and its response in the near-infrared region makes CdS QDs suitable for a wide range of applications.…”
