Book Description
A research is conducted to study on preparation of nitric acid from nitrogen dioxides using photocatalytic method. Due to the increasing pollution of oxides of nitrogen (NOx), production of nitric acid is vital in reducing the oxides of nitrogen release to the atmosphere. Nitric acids are one of the most important inorganic acids and commonly used as laboratory reagent and an important industrial commodity. Moreover, oxides of nitrogen are the major contributors to acid rain and ground-level ozone pollution. The main objective is to convert from waste to wealth by preparing nitric acid from industrial waste which is nitrogen dioxides. A photo-reactor with 1000 watt Metal Halide Lamp was used to optimize the production of nitric acid. The result from the experiment will be analyze and compared with the pure nitric acid. This method is efficient and economical.

Book Description
The book deals with novel aspects and perspectives in metal oxide and hybrid material fabrication. The contributions are mainly focused on the search for a new group of advanced materials with designed physicochemical properties, especially an expanded porous structure and defined surface activity. The proposed technological procedures result in an enhanced activity of the synthesized hybrid materials, which is of great importance when considering their potential fields of application. The use of such materials in different technological disciplines, including aspects associated with environmental protection, allows for the verification of the proposed synthesis method. Thus, it can be stated that those aspects are of interdisciplinary character and may be located at the interface of three scientific disciplines—chemistry, materials science, and engineering—as well as environmental protection. Furthermore, the presented scientific scope is in some way an answer to the continuous demand for such types of materials and opens new perspectives for their practical use

Book Description
Since 1988, there has been much literature published on the chemistry of nitric oxide, particularly in the field of S-nitrosation and the chemistry of S-nitroso compounds. Written by a chemist for the chemistry community, this book provides an update of the chemistry of nitrosation reactions, dealing with both the synthetic and mechanistic aspects of these reactions. It also looks at the chemistry of nitric oxide in relation to the amazing biological properties of this simple diatomic molecule, which were unknown until around 1990.* Provides an update on previously published literature on nitric oxide chemistry* Contains chapters on reagents for nitrosation, nitrosation at nitrogen, aliphatic and aromatic carbon, oxygen, sulfur and metal centres* Looks at hot research topics such as synthesis, properties and reactions of s-nitrosothiols

Book Description
Research for the development of more efficient photocatalysts has experienced an almost exponential growth since its popularization in early 1970’s. Despite the advantages of the widely used TiO2, the yield of the conversion of sun power into chemical energy that can be achieved with this material is limited prompting the research and development of a number of structural, morphological and chemical modifications of TiO2 , as well as a number of novel photocatalysts with very different composition. Design of Advanced Photocatalytic Materials for Energy and Environmental Applications provides a systematic account of the current understanding of the relationships between the physicochemical properties of the catalysts and photoactivity. The already long list of photocatalysts phases and their modifications is increasing day by day. By approaching this field from a material sciences angle, an integrated view allows readers to consider the diversity of photocatalysts globally and in connection with other technologies. Design of Advanced Photocatalytic Materials for Energy and Environmental Applications provides a valuable road-map, outlining the common principles lying behind the diversity of materials, but also delimiting the imprecise border between the contrasted results and the most speculative studies. This broad approach makes it ideal for specialist but also for engineers, researchers and students in related fields.

Book Description
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.
