Clean environment and green energy are the basic requirements of a sustainable human life. Semiconductor materials play a crucial role in addressing the issues related to increased global energy demand and environmental remediation. The development of photocatalysts has experienced almost exponential progress since their popularization in the early 1970s. Therefore, researchers have started to consider the diversity of photocatalysts globally by approaching this domain from a materials science perspective for applications in various areas. Recently, heterojunction photocatalytic materials have attracted a great amount of multidisciplinary research to face the global concerns of energy production and environmental protection. The unique potential of these technologies has been the stimulus to develop heterojunction photocatalysts with improved structural, morphological, and electronic properties, effectively increasing their efficiency. This book overviews the latest advances in this field, offering insights into the materials and applications of the latest generation of photocatalytic materials. It presents the challenges, future directions, and strategies for design within the area of heterojunction photocatalysts and will be a useful resource to enhance understanding of students, researchers, and academicians for promoting research in this field.

With escalating global population, increased consumption of fossil fuels, spiralling energy demand, rapid environmental degradation and global climate change, energy and environmental issues are receiving considerable attention worldwide from the purview of sustainable development. In order to address these complex and interlinked challenges, the development of new materials for affordable green energy technologies (batteries, supercapacitors, fuel cells and solar cells) and environmental remediation methods (adsorption, photocatalysis, separation, and sensing) is essential. Three-dimensional graphene-based macrostructures (3D GBMs) are of great interest in these applications given their large surface area and adaptable surface chemistry. Graphene-based 3D Macrostructures for Clean Energy and Environmental Applications provides a critical and comprehensive account of the recent advances in the development and potential applications of high performance 3D GBMs for tackling global energy and environmental issues in a sustainable manner. Particular attention is paid to the fabrication schemes, modulation of physiochemical properties, and their integration into practical devices, and the roles of surface chemistry and pore morphology, as well as their interplay, on the overall performance of 3D GBMs are examined. With contributions from authors around the world this book is a useful resource for both environmental scientists interested in sustainable energy and remediation solutions and materials scientists interested in applications for 3D GMBs.
