We report on an elaboration of new composite photocatalysts (TiO2–P25@ n-TiO2@HAP) based grafted size-selected 5-nm titanium-oxo-alkoxo nanoparticles P25-TiO2 and HAP obtained by co-precipitation salts. The oxo-TiO2 particles were prepared in a sol–gel reactor with rapid reagents micromixing. photocatalytic test ethylene degradation, continuous-flow fixed-bed reactor, showed increase the yield ...

Volatile organic compounds (VOCs) are air pollutants associated with health problem. Paints mixed photocatalytic (PC) materials considered to be effective in the removal of VOCs. Therefore, this investigation aimed produce a novel visible induced photocatalyst component paint. The synthesized photocatalysts (i.e., Ag/TiO2 and Fe/TiO2) were self-prepared by sol-gel method further used paints. ef...

This study presents a simple and sustainable coating technology for the deposition of photocatalytic coatings based on titanium dioxide geopolymers, which requires no thermal post-treatment. Titania powder P25, potassium silicate calcium aluminate-based hardener were dispersed in water applied to aluminum substrates using paintbrush, roller spray gun. The air-dried 12 h. activities tested via d...

One dimensional metal oxide nanostructures have attracted much attention owing to their fascinating functional properties. Among them, piezoelectricity and photocatalysts along with their related materials have stirred significant interests and widespread studies in recent years. In this work, we successfully transformed piezoelectric ZnO into photocatalytic TiO2 and formed TiO2/ZnO axial heter...

The principal purpose of this study is to present a new design for preparing highly active immobilized gold nanoparticle-based plasmonic photocatalysts. Gold nanoparticles were loaded on rutile TiO2 particles with a mean size of 80 nm (Au/TiO2) by the deposition precipitation method. The surface of SnO2 particles with a mean size of 100 nm was modified by copper(ii) oxide clusters (CuO/SnO2) wi...

J Abstract We report here a successful fabrication of a 3-D photoelectrode configuration having hydrothermally formed TiO2 nanotubes on parallel Ti fins. The Ti fin arrays were assembled by simple and facile spot welding of alternately tall and short Ti foil assembly, which provides signific...

In the present study treatability of persistent organic compounds from the flow back water after hydrauling fracturing was investigated. The combination of TiO2 photocatalyst and magnetic oxide nanoparticles enhance the separation and recoverable property of nanosized TiO2 photocatalyst. Fe3O4/TiO2 and Fe3O4@SiO2/TiO2 nanocomposites were prepared by heteroagglomeration. The photocatalysts' char...

Herein, we demonstrate the design and fabrication of the well-defined triple-shelled Ag@Fe3O4@SiO2@TiO2 nanospheres with burr-shaped hierarchical structures, in which the multiple distinct functional components are integrated wonderfully into a single nanostructure. In comparison with commercial TiO2 (P25), pure TiO2 microspheres, Fe3O4@SiO2@TiO2 and annealed Ag@Fe3O4@SiO2@TiO2 nanocomposites, ...
