"Materials Advances for Sustainable Environment and Energy: Theory, Status, and Challenges", book concisely summarise the possible ways to harvest hydrogen from water and also reduce CO2 into various hydrocarbons. A special emphasis is given on the figure-of-merits for the currently developed system/materials for hydrogen generation and CO2 reduction. We further have summarised the trends in materials innovation and the corresponding state-of-art to achieve the desired efficiency and stability considering the cost of production as well. Finally, the future prospects of this sustainable alternative fuel will be summarized for the possible future strategy in adopting these sustainable solutions at the commercial level. This book can be used as for developing understanding in this field in terms of fundamentals, materials advances, and devices deployment. The students and researchers from energy, environment, materials, chemistry, electrochemistry, etc., background will find it useful to stay unburst in this field"-- Provided by publisher.
