Metals as Clean Fuels explores the innovative use of metals as a sustainable energy source. It presents a scalable selective leaching method to activate metal fuels by increasing their surface-to-volume ratio, significantly enhancing their reactivity with water for hydrogen and heat generation. This approach positions metal fuels as a superior alternative to fossil fuels, offering higher energy density and the crucial benefit of generating energy without CO₂ emissions. Additionally, the book addresses key questions and working principles in its initial chapters before delving into the energy densities of various metals, from zinc to aluminum.

Chapters 8 and 9 focus on novel sustainable fabrication methods for metal/metal nanocomposites, while Chapter 10 introduces an advanced methodology for analyzing porous material systems. This monograph is a pioneering work in discussing nanostructured metals as clean fuels, with the potential to drive significant advancements in energy applications and material science research.
