This book focuses on the use of semiconducting metal oxides as gas sensing materials, including the sensing mechanism and sensing materials modification approach, while also providing a comprehensive introduction to semiconductor gas sensing devices. As an essential part of IoT (Internet of things), gas sensors have shown great significance and promising prospects. Therefore, studies on semiconducting metal oxides, one of the most important gas sensing materials, have increasingly attracted attention from various disciplines.
The book offers a valuable reference guide to metal oxide gas sensing materials for undergraduate and graduate students alike. It will also benefit all researchers who investigate metal oxides nanomaterials synthesis and gas sensing with relevant frontier theories and concepts. Engineers working on research and development for semiconductor gas sensors will also find new ideas in sensor design.
Dr. Yonghui Deng received his B.S. degree in Inorganic Chemistry from Nanchang University, China in 2000, and his Ph.D. degree in Polymer Chemistry and Physics from Fudan University, Shanghai, China, in 2005. From 2009 to 2010, Dr. Deng worked as a visiting scholar at the University of California, Berkeley. He has been a professor at Fudan University since 2011 and has published over 130 peer-reviewed journal papers with total citation over 10000 times. He received the second prize of the Ministry of Education's Natural Science Award and the National Science Fund Award for Excellent Young Scholars in 2014. He was also selected for the National Youth Top-Notch Talent Support Program, and as a Youth Cheung Kong Professor by the Ministry of Education in 2015. His research interests include functional porous materials and their applications in catalysis, as well as gas sensors.
