Summary:

An essential companion for catalysis researchers and professionals studying economically viable and eco-friendly catalytic strategies for energy conversion In the two-volume Heterogeneous Nanocatalysis for Energy and Environmental Sustainability, a team of distinguished researchers deliver a comprehensive discussion of fundamental concepts in, and practical applications of, heterogeneous nanocatalysis for alternative energy production, biomass conversion, solar energy, green fuels, H 2 production, fuel cells, electrochemical energy conversion processes, CO 2 conversion, clean water, and environmental protection. The volumes cover the design and catalytic performance of various nanocatalysts, including nanosized metals and metal oxides, supported metal nanoparticles, inverse oxide-metal nanocatalysts, core-shell nanocatalysts, nanoporous zeolites, nanocarbon composites, and metal oxides in confined spaces. Each chapter contains a critical discussion of the opportunities and challenges posed by the use of nanosized catalysts for practical applications. Volume 1 - Energy Applications focuses on the conversion of renewable energy (biomass/solar) into green fuels and chemicals, ammonia synthesis, clean hydrogen production, and electrochemical energy conversion processes using a variety of nanosized catalysts. It also offers: * A thorough introduction to heterogeneous catalysis and nanocatalysis, as well as a discussion of catalytic active sites at nano-scale range * Comprehensive explorations of the methods for control and activation of nanosized catalysts * Practical discussions of C 3 N 4 -based nanohybrid catalysts for solar hydrogen production via water splitting * Nanosized catalysts in visible light photocatalysis for sustainable organic synthesis * Applications of MXenes in electrocatalysis Perfect for researchers, postgraduate students, chemists, and engineers interested in heterogeneous catalysis and nanocatalysis, Heterogeneous Nanocatalysis for Energy and Environmental Sustainability will also earn a place in the libraries of professionals working in alternative energy production, biomass conversion, solar energy, green fuels, H 2 production, fuel cells, electrochemical energy conversion processes, CO 2 conversion, clean water, and environmental protection. Explore the environmental applications of heterogeneous nanocatalysis in the field of alternative energy production In Volume 2: Environmental Applications of Heterogeneous Nanocatalysis for Energy and Environmental Sustainability, a team of distinguished researchers discusses the foundational concepts and practical applications of heterogeneous nanocatalysis for alternative energy production. Volume 2 focuses on the purification of auto exhaust pollutants and volatile organic compounds, as well as CO2 conversion and wastewater treatment over a range of nano-sized catalysts.
