Speedy photoelectric exchange of CdSe quantum dots/mesoporous titania composite system

Preparation and near-infrared absorption of nano-SnO2/SiO2 assemblies with doping and without doping

“…As we know, the mesoporous solids possess very high absorption ability to heat. In order to improve or modulate the thermal absorption ability of mesoporous solids, the assemblies of nano-particles with the mesoporous solids were designed [8][9][10][11]. The near-infrared absorption study of the assemblies of nano-particles with the mesoporous solids has been reported [12].…”

Titania–silver and alumina–silver composite nanoparticles: Novel, versatile synthesis, reaction mechanism and potential antimicrobial application

“…As an excellent adsorbent, TiO 2 also enjoys a vast range of potential applications in photocatalysis [4][5][6], photovoltaics [7,8] and water splitting [9], either in its pristine form or as a composite with a variety of nanoparticles. Noble metals including Au [19] and Ag [20,21], magnetic particles such as Ni [22] and ferrites [23], quantum dots [24], hydroxyapatites [25] and various oxides (e.g. alumina [26], zirconia [27], silica [28] and NiO [29]) have been successfully incorporated on titania particles, rods, wires or mesh-like structures.…”

Electrospun TiO2 nanorods assembly sensitized by CdS quantum dots: a low-cost photovoltaic material

“…[20][21][22] Among the semiconductor QDs sensitizing materials, CdS is a promising candidate for its band gap of 2.4 eV and flat band edge at À0.66 V (pH ¼ 7), rendering it able to absorb visible light and form a favourable band alignment with TiO 2 for efficient electron injection (Scheme 1). [23][24][25] To deposit CdS onto TiO 2 , successive ion layer adsorption and reaction (SILAR), sometimes also referred to as chemical bath deposition (CBD), is a facile method which is widely used in QD-sensitized solar cells. [26][27][28] Here we report a novel nanostructure of electrospun TiO 2 NRs@CdS by fabricating the TiO 2 electrode (as explained in detail below) followed by deposition of CdS QDs via SILAR.…”
