Special materials with special properties: The book summarizes the science and technology of layered photocatalytic materials with a particular emphasis on environmental and energy applications.

Liqun Ye works at China Three Gorges University in Yichang City, as a full professor of chemistry. He got a Ph.D. degree in chemistry from Wuhan University in 2013. From 2015 to 2016, Prof. Ye worked in prof Wong's group as a Research Assistant in The Chinese University of Hong Kong. His expertise is focused on photophysics and photochemistry of nanostructured materials. His current research interest is to develop efficient photocatalytic approaches to solar energy conversion and utilization by harnessing solar energy to produce molecular fuels and to degrade environmental pollutants. In the near decade, Prof. Ye, acting as the project principal, has completed and is conducting more than 10 important research items, like NSFCs. As the first and/or corresponding author, he has published over 100 professional papers in the international SCI journals. These papers have been positively cited for more than 10000 times. He also is "highly cited scientists" of Clarivate Analytics. Dehua Xia, professor and doctoral supervisor, received his bachelor's, master's and doctor's degrees from Sun Yat-sen University and the Chinese University of Hong Kong successively. After his doctorate in 2014, he went to the University of Hong Kong and the Hong Kong University of Science and Technology for postdoctoral research. In July 2017, he joined the School of Environment of Sun Yat-sen University. He is mainly engaged in research on environmental microinterface chemical processes and pollution control.He has published more than 100 SCI papers,includign Nature Communication, ACS Nano, Adv.Func. Mater., ES&T, Water Res., App.catal. B:Environ.He is the Winner of the Outstanding Youth Fund of Guangdong Natural Science Foundation, "Yat-sen Scholar" of Sun Yat-sen University, "100 People Program" of Sun Yat-sen University, also selected in the world's top 2% top scientists list, second prize of China Environmental Protection Industry Association Environmental Technology Progress Award and other honors.
