Available in PDF, EPUB and Kindle. Book excerpt: Photocatalyst has been established as one of the promising technique for environmental purification technology especially used for air pollutants removal. The development and innovation of semiconductor materials which has an ability to degrade the organic contaminants in air are highly desirable. In this dissertation, a promising photocatalyst of TiO2-SiO2 thin film was synthesized via a simple sol-gel method accompanied by the spin coating process. The study on the effect of insertion a second semiconductor material on the physical and chemical properties of the TiO2 thin film photocatalyst is necessary in order to find a better way for enhancing the photocatalytic activity of the thin film photocatalyst. From XRD analysis, it was found that the thin film obtained was fully anatase crystal structure after calcined at 500 °C for 7 hours. The suppressive effect on the TiO2 crystal growth was observed for lower content of SiO2. Besides, the effect of using different metal alkoxide to synthesize the precursor solution is beneficial to find the desired characteristic of thin film photocatalyst. It was observed that TiO2 particles of PTP derived thin film and powder was smaller than that of TPT derived thin film and powder due to different hydrolysis rate of the metal alkoxide. FESEM picture showed that nanosized and spherical particle was obtained. With the aim of finding the main factor of the photocatalytic activity of the TiO2-SiO2 thin film photocatalyst, a kinetic study using a Langmuir- Hinshelwood kinetic model is employed. Photocatalytic activity of the TF95/5 and TF90/10 thin film photocatalyst was evaluated on degrading acetaldehyde gas. TF90/10 thin film photocatalyst showed better adsorption property due to its high surface area. However, TF95/5 thin film photocatalyst showed higher degradation rate of decomposing the acetaldehyde gas molecules due to high crystallinity of the thin film photocatalyst leading to better charge separation and produce more charge carriers.

Available in PDF, EPUB and Kindle. Book excerpt: Although the seminal work of Fujishima et al. dates back to 1971, TiO2 still remains the most diffused and studied semiconductor, employed in photo-oxidation processes for cleantech (i.e., polluted water and air treatment), in solar fuel production (mainly hydrogen production by water photo splitting), and in Carbon Capture and Utilization (CCU) processes by CO2 photoreduction. The eleven articles, among them three reviews, in this book cover recent results and research trends of various aspects of titanium dioxide photocatalysis, with the chief aim of improving the final efficiency of TiO2-based materials. Strategies include doping, metal co-catalyst deposition, and the realization of composites with plasmonic materials, other semiconductors, and graphene. Photocatalysts with high efficiency and selectivity can be also obtained by controlling the precise crystal shape (and homogeneous size) and the organization in superstructures from ultrathin films to hierarchical nanostructures. Finally, the theoretical modeling of TiO2 nanoparticles is discussed and highlighted. The range of topics addressed in this book will stimulate the reader’s interest as well as provide a valuable source of information for researchers in academia and industry.

Available in PDF, EPUB and Kindle. Book excerpt: Smart ceramic coatings containing multifunctional components are now finding application in transportation and automotive industries, in electronics, and energy, sectors, in aerospace and defense, and in industrial goods and healthcare. Their wide application and stability in harsh environments are only possible due to the stability of the inorganic components that are used in ceramic coatings. Ceramic coatings are typically silicon nitride, chromia, hafnia, alumina, alumina-magnesia, silica, silicon carbide, titania, and zirconia-based compositions. The increased demand for these materials and their application in energy, transportation, and the automotive industry, are considered, to be the main drivers. Advanced Ceramic Coatings for Energy Applications covers recent developments in conducting electrodes, photovoltaics, solar cells, battery applications, fuel cells, electrocatalysts, photocatalysts and supercapacitors.

This book was released on 2011 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprising about 70% of the Earth's surface, water is undoubtedly the most precious natural resource. According to the W.H.O, around 3.5 million people are dying every year from different water related diseases. Different kinds of dyes and pharmaceutical products have been detected in drinking water, all over the world. These organic compounds being non removable by traditional water purification processes, made advanced oxidation processes come into existence. Among all kind of advanced oxidation processes, photocatalytic oxidation is the most promising one. The photocatalytic process is based on aqueous phase hydroxyl radical chemistry and couples low energy UV light with semiconductors acting as photocatalyst. The slurry form of TiO2 though being efficient has several disadvantages (particularly, post treatment expensive separation steps) which brings the immobilization of the catalysts on surfaces into existence. In this study, a TiO2-polymeric film photocatalyst was synthesized by reaction of gelatin, polyvinyl alcohol and polyvinyl pyrrolidone. TiO2 Degussa P25 powder was embedded into the polymeric matrix. The characterization of the film by OM, SEM, FTIR, revealed the topography of the catalyst films. Optimization of photocatalysts functionality was carried out by varying the cross linking methods and conducting several photodegradation reactions both under UV and solar light. Aspirin and methyl orange were chosen as model compounds, as traces of these compounds were detected in the drinking water of South-Western Ontario. The freeze-dried film photocatalyst was observed to degrade organic compounds efficiently, under both UV and solar illuminations. Degradation of high concentrated organic pollutants, was observed to follow Langmuir-Hinshelwood kinetics while at low concentration, first-order kinetics was observed. The effects of initial concentration, flow rate, pH, light intensity, photocatalyst loading, and thickness of the film on the degradation rates were studied. Mechanism of degradation of aspirin was studied from LC/MS analysis. The TOC analysis was carried out to analyse the organic carbon content of the intermediates formed during the course of degradation. Finally, photocatalytic degradation reaction was carried out in a continuous flow reactor under LED lights. film photocatalyst holds the potential of being an efficient and economical form of future photocatalyst for water purification.
