This book features various approaches to non-biochemical pathways for solar fuel production. This one-of-a-kind book addresses photovoltaics, photocatalytic water splitting for clean hydrogen production, and CO2 conversion to hydrocarbon fuel through in-depth comprehensive contributions from authors from across the world. This book intends to serve as a primary resource for a multidisciplinary audience including chemists, engineers, and scientists providing a one-stop location for all aspects related to solar fuel production. The content of this book strikes a balance between theory, material synthesis, and application with the central theme being solar fuels.
