Solar Light-to-Hydrogenated Organic Conversion


Book Description

This book highlights the promising photocatalytic methods for synthesizing organic chemicals by simultaneously degrading the toxicity of raw substances used for organic synthesis. It presents various semiconducting materials with high catalytic activities in hydrogen evolution reactions (HERs) and hydrogenation reactions, as well as the material characterizations for identifying semiconductor photocatalysts. The focus is on understanding the hydrogen dissociation and activation of substances in the process of hydrogenation and the fabrication of nanostructured catalysts with desired activity and selectivity. Recent works show photocatalytic hydrogenation reactions with in situ generated H+ on catalyst surfaces utilizing initial chemicals such as nitrophenol, nitrobenzene, azobenzene, and benzene for valorization. In addition, the photocatalytic valorization of waste glycerol is also discussed. Besides the hydrogenation reactions, the reduction of oxygen to form H2O2 can be done with a photocatalytic method in atmospheric conditions. Some related perspectives and outlooks are also discussed for possible future development.










Solar to Chemical Energy Conversion


Book Description

This book explains the conversion of solar energy to chemical energy and its storage. It covers the basic background; interface modeling at the reacting surface; energy conversion with chemical, electrochemical and photoelectrochemical approaches and energy conversion using applied photosynthesis. The important concepts for converting solar to chemical energy are based on an understanding of the reactions’ equilibrium and non-equilibrium conditions. Since the energy conversion is essentially the transfer of free energy, the process are explained in the context of thermodynamics.
