Description
Design Criteria for Next-Generation Bio and Synthetic Nanomaterials in Hydrogen Production examines the potential of hydrogen as a crucial energy vector for the transition to clean energy. It discusses advanced water electrolysis methods and various systems, including proton and anion exchange membranes, alkaline systems, and solid oxide systems. The book covers a range of hydrogen production methods, including pyrolysis, photocatalysis, and bio-inspired approaches. It highlights the integration of 3D printing technology to fabricate components for photocatalytic systems and custom catalysts, as well as the development of scalable solutions to improve efficiency and reduce costs. Additionally, it addresses the conversion of waste into hydrogen feedstock and examines the role of biosynthesized nanomaterials as innovative catalysts. Coverage includes a discussion of integrating hybrid bio-nanomaterials with synthetic nanomaterials, outlining design criteria for the next generation of nanomaterials that focus on mechanisms, scalability, applications, and environmental safety considerations.
