Book excerpt: Photocatalysis is a reaction which is accelerated by light while a heterogeneous reaction consists of two phases ( a solid and a liquid for example). Heterogeneous Photocatalysis is a fast developing science which to date has not been fully detailed in a monograph. This title discusses the basic principles of heterogeneous photocatalysis and describes the bulk and surface properties of semiconductors. Applications of various types of photoreactions are described and the problems related to the modeling and design of photoreactors are covered.

This book was released on 1993 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mineralization of trichloroethylene (TCE) and tetrachloroethylene (PCE) in gas stream from a soil vapor extraction (SVE) well was demonstrated with an annular photocatalytic reactor packed with porous TiO2 pellets in field trials at the Savannah River Site in Aiken, SC. The TiO2 pellets were prepared using a sol-gel method. The experiments were performed at 55 to 60°C using space times of 108 to 101° g s/mol for TCE and PCE. Chloroform (CHCl3) and carbon tetrachloride (CCl4) were detected as minor products from side reactions. On a molar basis, CCl4 and CHCl3 produced were about 2% and 0.2 % of the reactants.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indoor air quality (IAQ) concern has risen since people spend most of their time (>90%) in indoor environments. Volatile organic compounds (VOCs) are categorized as a major group of gas pollutants. Indoor VOCs, known as hazardous compounds with several proven adverse health effects. Among various purification techniques, a heterogeneous photocatalytic oxidation process (PCO) is a promising technology for removing indoor VOC contaminants. Titanium dioxide (TiO2) is the leading candidate for PCO given its unique properties. However, no TiO2-based photocatalysts completely satisfy all practical requirements, considering the photoexcited charge carriers' short lifetime and a wide band gap requiring ultraviolet (UV) radiation. Moreover, the application of PCO for VOCs degradation is greatly hindered at high humidity levels. Herein, TiO2 modification techniques that include approaches for overcoming the inherent TiO2 limitations and improving the photocatalytic degradation of VOCs are studied. In this research, strategies for improving TiO2 photocatalyst activities by doping with different metal and/or non-metal ions as well as surface modification have been examined. Accordingly, the adsorption capacity and photocatalytic activity of P25 and surface fluorinated P25 coated on nickel foam were evaluated for VOCs removal. In addition, the photoactivity of visible-light-driven photocatalysts including; anatase/rutile carbon-doped P25, anatase/brookite cerium-doped TiO2, and anatase/brookite iron-doped TiO2 coated on nickel foam were evaluated for degradation of VOCs under both UV and visible light irradiation. Surface fluorination was then applied to reduce the surface hydrophilicity of Ce-TiO2 and Fe-TiO2 photocatalysts with the optimum Ce and Fe contents. Notably, their photocatalytic performance was investigated in continuous flow mode-of-operation reactors with small residence time, different relative humidity levels, and low-level inlet contaminant concentration. These techniques can improve PCO performance through the following mechanisms: i) by introducing an electron capturing level in the band gap that would generate some defects in the TiO2 lattice and help capture charge carriers and can also be excited under visible irradiation; ii) by slowing down the charge carrier recombination rate and increasing VOCs degradation; and iii) by reducing the surface hydrophilicity, which increases VOCs' adsorption capacity at high humid conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Available in PDF, EPUB and Kindle. Book excerpt: The semiconductor titanium dioxide (TiO2) has been evolved as a prototypical material to understand the photocatalytic process, and has been demonstrated for various photocatalytic applications such as pollutants degradation, water splitting, heavy metal reduction, CO2 conversion, N2 fixation, bacterial disinfection, etc. Rigorous photocatalytic studies on TiO2 have paved the way to understanding the various chemical processes involved and the physical parameters (optical and electrical) required to design and construct diverse photocatalytic systems. Accordingly, it has been realized that an effective photocatalyst should have ideal band edge potential, narrow band gap energy, reduced charge recombination, enhanced charge separation, improved interfacial charge transfer, surface-rich catalytic sites, etc. As a result, many strategies have been developed to design a variety of photocatalytic systems, which include doping, composite formation, sensitization, co-catalyst loading, etc. Towards highlighting the above-mentioned diversities in TiO2 photocatalysis, there have been many interesting original research works on TiO2, involving material designs for various photocatalytic applications published in this Special Issue. In addition, some excellent review papers have also been published in this Special Issue, focusing on the various TiO2-based photocatalytic systems and their mechanisms and applications.
