Photocatalysis is an advanced oxidation process for the purification and remediation of contaminated waters and wastewaters, and is advantageous over conventional treatment technologies due to its ability to degrade emerging and recalcitrant pollutants. In addition, photocatalytic disinfection is less chemical-intensive than other methods such as chlorination, and can inactivate even highly resistant microorganisms with good efficacy. Process sustainability and cost-effectiveness may be improved by utilizing solar irradiation as the source of necessary photons for photocatalyst excitation. However, solar-induced activity of the traditionally-used titania is poor due to its inefficient visible light absorption, and recombination of photo-excited species is problematic. Additionally, mass transfer limitations and difficulties separating the catalyst from the post-treatment slurry hinder conversions and efficiencies obtainable in practice. In this research, various strategies were explored to address these issues using novel visible light active photocatalysts. Two classes of carbon-enhanced photocatalytic materials were studied: activated carbon adsorbent photocatalyst composites, and carbon-doped TiO2. Adsorbent photocatalyst composites based on activated carbon and plasmonic silver/silver chloride structures were synthesized, characterized, and experimentally investigated for their photocatalytic activity towards the degradation of model organic pollutants (methyl orange dye, phenol) and the inactivation of a model microorganism (Escherichia coli K-12) under visible light. The adsorptive behaviour of the composites towards methyl orange dye was also studied and described according to appropriate models. Photocatalytic bacterial inactivation induced by the prepared composites was investigated, and the inactivation mechanisms and roles of incorporated antimicrobial silver on disinfection were probed and discussed. These composites were extended towards magnetic removal strategies for post-use separation through the incorporation of magnetic nanoparticles to prepare Ag/AgCl-magnetic activated carbon composites, and the effect of nanoparticles addition on the properties and photoactivities of the resulting materials was explored. Another silver/silver halide adsorbent photocatalyst composite based on activated carbon and Ag/AgBr exhibiting visible light absorption due to both localized surface plasmon resonance and optical band gap absorption was synthesized and its photocatalytic activity towards organics degradation and microbial inactivation was studied. Carbon-doped mixed-phase titania was also prepared and experimentally investigated.

New and Future Developments in Catalysis is a package of seven books that compile the latest ideas concerning alternate and renewable energy sources and the role that catalysis plays in converting new renewable feedstock into biofuels and biochemicals. Both homogeneous and heterogeneous catalysts and catalytic processes will be discussed in a unified and comprehensive approach. There will be extensive cross-referencing within all volumes.The use of solar energy during various catalytic chemical processes for the production of an array of chemical products is the theme of this volume. Photocatalysis is a topic of increasing importance due to its essential role in many of today’s environmental and energy source problems. The use of solar energy for catalytic reactions results in a carbon dioxide–neutral process. All photocatalytic processes and the future developments in this area are discussed, including an economic analysis of the various processes. Offers in-depth coverage of all catalytic topics of current interest and outlines future challenges and research areas A clear and visual description of all parameters and conditions, enabling the reader to draw conclusions for a particular case Outlines the catalytic processes applicable to energy generation and design of green processes

Nanostructured Photocatalysts: From Materials to Applications in Solar Fuels and Environmental Remediation addresses the different properties of nanomaterials-based heterogeneous photocatalysis. Heterogeneous nanostructured photocatalysis represents an interesting and viable technique to address issues of climate change and global energy supply. Sustainable hydrogen (H2) fuel production from water via semiconductor photocatalysis, driven by solar energy, is regarded as a viable and sustainable solution to address increasing energy and environmental issues. Similarly, photocatalytic reduction of CO2 with water for the production of hydrocarbons could also be a viable solution. Sections cover band gap tuning, high surface area, the short diffusion path of carriers, and more. Introduces the utilization of nanostructured materials in heterogeneous photocatalysis for hydrogen fuel production via water splitting Explains preparation techniques for different nanomaterials and hybrid nanocomposites, enabling improved sunlight absorption efficiency and enhanced charge separation Assesses the challenges that need to be addressed before this technology can be practically implemented, particularly of identifying cost-effective nanophotocatalysts

This book will be a guiding path to understand the photocatalytic process and mechanism for the deterioration of heavy metals, persistent organic pollutants and pathogens from wastewater. Environmental remediation is of crucial importance in the context of human sustainability in the present and future times. The unplanned anthropogenic activities and revolutionary industrialization end up in environmental contamination with noxious organic-inorganic and biogenic pollutants. The photocatalytic disinfection and detoxification is the only solution to preserve and restore the ecological balance. The main emphasis is to explore and enhance the photocatalytic potentials of solar active-materials.
