Reseña del libro "Trends and Contemporary Technologies for Photocatalytic Degradation of Dyes (en Inglés)"
Chapter 1: Introduction to Photochemistry of DyesThis chapter will deal with the basic chemistry of dyes and the effect of various factors (oxygen, temperature and humidity, atmospheric contaminants and concentration of dye) on the degradation of dyes will be discussed.The kinetics of photocatalytic dyestuff degradation will be considered. Chapter 2: Heterogeneous photocatalytic degradation of dyes: Fundamental principles and its applications This chapter covers the critical selection of heterogenous materials for photocatalysis based on the chemical, physical, and selective nature of the poisoning dyes. The main core highlighted in this chapter is the significant application of semiconductors for photocatalysis based on the chemical, physical, and selective nature of the dyes. Chapter 3: Recent developments in photocatalytic techniques of dye degradation in effluents. This chapter covers the photocatalysis aiming at mineralization of dyes to CO2, H2O and inorganic compounds or their transformation into biodegradable or harmless products using novel materials and techniques. Chapter 4: Role of doped semiconductors in the catalytic activity his chapter cover photocatalysts such as ZnS, CdS, CuS, Ag2S, Bi2S3, CoS, FeS, and PbS as well as the effects of a range of parameters such as dopants, band gap, size, light intensity, surface area, reaction time, pH and degradation efficiency, heterojunctions, etc. on the degradation of dyes. Chapter 5: Hybrid Treatment technologies for dye degradation in wastewater This chapter covers an in-depth evaluation of broad range of potential hybrid technologies since a single technology cannot explain the whole process of degradation. In addition this chapter will emphasize on the importance of hybrid technologies, as well as energy and water reuse plan within the treatment scheme. Chapter 6: Degradation of Azo Dyes under Visible Light Irradiation This chapter covers dyes which are widely used in the textile industry, and which can be effectively degraded by a photocatalytic treatment using a catalyst under visible light irradiation. It will include an analysis of the effects on the dye removal efficiency of the major process parameters which will result in the effective treatment and can be optimized to provide rapid and complete degradation. The use of visible light as a cost-effective method for the removal of dyes from textile effluents. Chapter 7: Enhancement in catalytic activity using visible range of irradiation This chapter covers the enhanced photocatalytic materials for a better performance and could be accredited to the strong visible light absorption and low recombination rate. It will discuss the photo-Fenton-like catalysis activity of the materials under visible light and underlying mechanism of the catalytic material for the degradation of colouring substances. Chapter 8: Mathematical modelling for nanoparticle induced dye degradation. This chapter covers the application of a mathematical model as a powerful tool to describe the degradation processes and to elucidate the quantitative degradation performance and the optimization of biodegradation processes. It will further be beneficial for development of technologies for process intensification Chapter 9: Effective Materials in the Photocatalytic Treatment of Dyestuffs and Stained Wastewater This chapter covers the effectiveness and evaluation of the photocatalytic treatment and the photocatalytic efficiency in the treatment of dyestuffs and stained wastewater coming from various factories. The materials employed as photocatalysts in the degradation of commercial dyestuffs sol
