Water (H O) is a very 2 fantastic substance for us. For a long period of time, humans have been consideringhowtoimprovethewaterenvironmentsofourplanet.Wethree got acquainted because of water. The area we work in is environmental engineeringforwatertreatment.Purificationofcontaminatedwaterisaway to maximize its value. For example, good water can produce good wine. We have devoted all our lives to such a great cause. In the 1950s, Richard Phillips Feynman’s great speech ‘‘There’s Plenty of Room at the Bottom’’ opened a precedent for nanotechnology. In my (Wen Liu)classof‘‘EnvironmentalNanotechnology’’,IalwaystellFeynman’sstory to the students. They are guided to explore the essence of the micro- and nano-world, and meanwhile, to appreciate the romance of a scientist’s life. Actually, literature, art and science are inherently interrelated. It is so excitingthattechnologyiswhereitistoday,sowecanlearnmoreaboutthe ‘‘bottom’’.WearedelightedthatwecanprovideEmergingNanotechnologies for Water Treatment for you all. A link is needed to connect the macro-scale water world and micro-scale nanoworld.Ametaphorforthislinkcouldbeseeninthe‘‘knot’’mentioned in Makoto Shinkai’s animated movie, Your Name. Today, we happily find that nanomaterials act as knots in this way. It’s our great pleasure to show you this connection caused by nanotechnology. Since we share a common enthusiasm in this topic, we got together to prepare this book. There is an old saying that the friendship between gentlemen is as pale as water, while we believe it is thicker than water. We also offer our acknowledgement to Dionysios D. Dionysiou, who is the Editor-in-chief of this series of Royal Society ofChemistry books, andwhosenameissimilartothat ofDionysus, the ancient Greek god associated with wine. ChemistryintheEnvironmentSeriesNo.4 EmergingNanotechnologiesforWaterTreatment EditedbyYanbiaoLiu,Chong-ChenWangandWenLiu rTheRoyalSocietyofChemistry2022 PublishedbytheRoyalSocietyofChemistry,www.rsc.org v vi Preface In the future, we will continue to be proud of water and nanotechnology. Contaminated water treated using nanotechnology is the ultimate goal pursued by us, and thus the water quality is significantly upgraded.
