We report on a new approach for the synthesis of TiO2-pillared montmorillonite, where the pillars exhibit a high degree of crystallinity (nanocrystals) representing a mixture of anatase and rutile phases. The structures exhibit improved adsorption and photocatalytic activity as a result of hydrothermally activated intercalation of titanium polyhydroxo complexes (i.e., TiCl4 hydrolysis products)...

Anatase phase containing nano-crystallite TiO2 thin film is prepared by the peptization of modified Ti-isopropoxide sol using HNO3 as peptizing agent. The resulting sol is concentrated in a rotary evaporator bath. TiO2 film is deposited on ITO substrate by spin coating process. The compact film is annealed at 450 ̊C and 500 ̊C for optical studies. The subsequently it is modified as photo-anodes i...

The rational design of nanoheterostructured materials has attracted much attention because of its importance for developing highly efficient LIBs. Herein, we have demonstrated that internal Mo(6+) doped TiO2 nanocrystals in situ decorated with highly dispersed MoO3 clusters have been realized by a facile and rapid flame spray pyrolysis route for electrochemical energy storage. In such intriguin...

Based on a diblock-copolymer templated sol–gel synthesis, germanium nanocrystals (GeNCs) are introduced to tailor mesoporous titania (TiO2) films for obtaining more efficient anodes photovoltaic applications. After thermal annealing in air, the hybrid with different GeNC content investigated and compared undergoing an argon atmosphere annealing. The surface inner morphologies of TiO2/GeOx nanoc...

The Sn-modified TiO2 photocatalysts are prepared by low-temperature sol-gel processing based on organic titanium and tin precursors with varied Sn concentrations (from 0.1–20 mol .%). role of dopant as the promotor formation rutile crystalline phase is explained optimal concentration for preparation efficient titania photocatalyst determined. Up to 40 % increase in photocatalytic activity achie...

This communication describes a facile and mild chemical etching method for resizing of CdTe nanocrystals, which provides a possible approach for tailoring the size-dependent properties of the nanocrystals.
