One of the main goals 21st century chemistry is to replace environmentally hazardous processes with energy efficient routes allowing totally avoid use and production harmful chemicals maximise quantity raw material that ends up in final product. Selective photocatalytic conversions will play a major role this evolution account shows how photocatalysis offering an alternative green route for organics.
Brookite is the least studied TiO2 photocatalyst due to difficulties usually encountered in order obtain it as a pure phase. In this review, comprehensive survey of different methods available for preparing brookite powders and films reported. Attention has been paid both most traditional methods, such hydrothermal processes at high temperatures pressures, environmentally benign syntheses using water soluble compounds solvent. Papers reporting photocatalytic activity brookite-based samples...
A set of polycrystalline TiO2 photocatalysts loaded with various ions transition metals (Co, Cr, Cu, Fe, Mo, V, and W) were prepared by using the wet impregnation method. The samples characterized some bulk surface techniques, namely X-ray diffraction, BET specific area determination, scanning electron microscopy, point zero charge femtosecond pump−probe diffuse reflectance spectroscopy (PP-DRS). employed as catalysts for 4-nitrophenol photodegradation in aqueous suspension, used a probe...
Selective photocatalytic oxidation of aromatic alcohols to aldehydes was performed in water the presence TiO2 rutile photocatalysts that exhibited a low degree crystallinity. The nanostructured samples, prepared ex TiCl4 at very temperature, ensured selectivity toward aldehyde 3 4-fold higher than commercial tested (Sigma-Aldrich).
This glossary of terms covers phenomena considered under the very wide photocatalysis and radiation catalysis . A clear distinction is made between related to either photochemistry or chemistry catalysis. The term “radiation” used here as embracing electromagnetic all wavelengths, but in general excluding fast-moving particles. Consistent definitions are given areas mentioned above, well most important parameters for quantitative description phenomena. Terms up-scaling photocatalytic...
Selective photocatalytic conversions are offering an alternative green route for replacing environmentally hazardous processes with safe and energy efficient routes. This paper reports the most recent advances in application of heterogeneous photocatalysis to synthesize valuable compounds by selective oxidation reduction.
This review deals with the parameters that influence heterogeneous photocatalysis (PC) for selective synthesis of high-value chemicals by itself or in combination other technologies. In particular, related to photocatalysts, such as crystallinity degree, type polymorph, surface acid–base properties, exposure particular crystalline facets, coupling different semiconductors, position valence and conduction band edge, addition doping agents, those reaction system, setup configuration reactor...

Abstract The results of a study photocatalytic degradation phenol using aqueous oxygenated TiO2 (anatase) suspensions in batch Pyrex photoreactor are reported. influence on the photodegradation rate various parameters as pH, and content, oxygen partial pressure, anions present dispersions was investigated. A complete oxidation observed. Intermediate compounds, catechol quinone, were detected. It observed that also proceeded with sunlight radiation. mechanistic kinetic model, which accounts...

Electron spin resonance spectroscopy (ESR), Fourier transform infrared (FTIR), and monitoring of pyridine (py) boric acid trimethyl ester (BATE) adsorption for determining surface acidity basicity, respectively, were used to carry out further characterization mixed ZnO/TiO2 polycrystalline solids prepared by different methods. Moreover, the powders tested in a batch photoreactor probe reaction, i.e., 4-nitrophenol photodegradation aqueous medium. ESR results indicated presence signals...
The photocatalytic degradation of the anthraquinonic dye Acid Blue 80 in aqueous solutions containing TiO2 dispersions has been investigated. process monitored by following either disappearance (via HPLC) and formation its end-products IC, GC, TOC analysis). Although a relatively fast decolorization observed, mineralization is slower, presence residual organic compounds was evidenced even after long term irradiation, confirming relevant stability anthraquinone derivatives. identification...
