Welcome to this episode of the Big Picture Podcast. Co-hosts John and Tracy Suchocki interview professor Raj Rajeshwar, one of the leading researchers in the exciting area of solar fuels, which are fuels generated directly from sunlight. We explore the chemistry behind the many challenges still faced in the development of solar fuels. We talk about the prospects. About the possibilities. This is perhaps one of our more technical episodes. It assumes the listener has a basic understanding of chemical reactions, particularly oxidations and reductions. But for all listeners, much value and insight is provided. Duration: 47:39.
