Herein, the synthesis, characterization and photocatalytic application of a novel hybrid polyoxometalate, which can absorb light in the visible region, are reported. This hybrid material was synthesized by attaching a monovacant polyoxometalate, (SiW11O39), through a (3-aminopropyl)triethoxysilane linker to the anthracene. The hybridization with anthracene drastically decreased the band gap of ...

An excellent ternary composite photocatalyst consisting of silver orthophosphate (Ag3PO4), attapulgite (ATP), and TiO2 was synthesized, in which heterojunction was formed between dissimilar semiconductors to promote the separation of photo-generated charges. The ATP/TiO2/Ag3PO4 composite was characterized by SEM, XRD, and UV-vis diffuse reflectance spectroscopy. The co-deposition of Ag3PO4 and ...

Abstract. Titania (TiO2) is one of the most unique catalysts, crucially important in photo-green chemistry. The mesoporous TiO2 has large surface area, uniform pore size and open frameworks for the transfer of mass and charges. TiO2 has photocatalytic activity which can degrade both organic and inorganic compounds. The band gap energy of TiO2 can be modified by doping various metal oxides to ma...

It is known that TiO2 exhibits good photocatalytic properties which could be used in various commercial applications such as water and air purification or photo-induced biodegradation of microbes. TiO2 occurs in nature in the form of three crystal polymorphs: anatase, brookite and rutile. For photocatalytic applications only anatase and rutile are of interest, however anatase shows greater phot...

A novel heterostructure was first synthesized by directly depositing photocatalytic inert ZnO2 onto facet {201} of brookite nanorods. The heterostructure thus obtained was found to show a superior photocatalytic activity under UV-light irradiation. The exceptional photocatalytic performance was due to the band-structure match between ZnO2 and brookite as well as synergic charge accumulation by ...

In this work, growth and assembly of the micro polyhedral zinc oxide was performed using airbubble assisted Triton X100, as a templating agent. In absence of air bubbling in the reactionsystem the nano plate zinc oxide was synthesized. The prepared samples were characterized by Xraydiffraction (XRD), field emission scanning electron microscopy (FE-SEM) and UV-Visspectrop...

To investigate the effect of Gd doping on photocatalytic activity of BiFeO3 (BFO), Gd-doped BFO nanoparticles containing different Gd doping contents (Bi(1-x)GdxFeO3, x = 0.00, 0.01, 0.03, 0.05) were synthesized using a facile sol-gel route. The obtained products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectra,...

The facet-engineered surface and interface design for photocatalytic materials has been proven as a versatile approach to enhance their photocatalytic performance. This review article encompasses some recent advances in the facet engineering that has been performed to control the surface of mono-component semiconductor systems and to design the surface and interface structures of multi-componen...

This review provides a background, fundamental and advanced application of titania nanoparticles (TiO2) on the disinfection and killing of cancer cell through photocatalytic chemistry. It starts with the characteristic properties focused on the surface, light sensitivity, crystallinity and toxicology of TiO2 as a photocatalyst. Consequently, outline and design of photocatalytic reactor has been...

Photocatalytic oxidation (or photocatalysis) can be used to convert undesirable compounds present in gas or liquid samples into carbon dioxide and water. Photocatalyst materials are “self-generating”, making the process especially attractive in moderate and long-term applications where consumable materials are to be avoided (e.g., Space Shuttle cabins and in the International Space Station). Ph...
