Description

S-scheme Heterojunction Photocatalysts Fundamentals and Applications clearly describes photocatalytic processes and mechanisms, reviews the history of traditional heterojunction, discusses the problems of charge transfer in some heterojunctions, states the necessity in proposing S-scheme photocatalyst, and provides, in detail, the design principles and characterization protocols for the emerging S-scheme heterojunction. Examples of S-scheme heterojunctions classified by material types are summarized, and the book provides a comprehensive discussion on design, fabrication, principle, mechanism, characterization, and application of S-scheme heterojunction photocatalyst.

This book provides state-of-art research frontiers in this area that will appeal to experienced researchers and graduate students, as well as research and development scientists in the nanosized-composite-related industry.

Key features

  • Provides the latest advances in this topic area, offering insights into the materials and applications of the hybrid materials
  • Helps distinguish correct explanations from invalid ones and clears up historical misunderstandings in the field
  • Provides new perspectives in charge carrier migration
  • Enlightens readers to help them design and develop novel photocatalysts of their own with improved efficiency

Readership

This book is primarily intended for experienced postdoctoral researchers and academics in the field of photocatalysis in chemical engineering, as well as graduate students in this area will also benefit from reading this book. Research and development scientists in the nanosized-composite-related industry are also a key audience. Graduate students from the disciplines of materials science, chemistry, energy, environmental science, and engineering. Also, some upper-level undergraduate students taking photocatalysis/electrocatalysis-related classes will be able to read chapters as assigned by class instructors. The book may serve the reader better if they have basic knowledge on solid state physics or semiconductor physics.
