Elisa I. García López is an associate professor of chemistry at Università di Palermo, Italy. She obtained her bachelor’s degree in chemistry from the Universidad Autónoma de Madrid (UAM) and her PhD in chemistry and materials science from the Università di Palermo. She worked as a postdoctoral fellow at Meisei University, Japan. Her research interests are focused on heterogeneous photocatalysis. She is coauthor of more than 100 papers in collaboration with scientists from all over the world, more than 200 communications for international congresses, and 10 book chapters. Leonardo Palmisano was born in Termini Imerese, Italy, in 1950. He obtained his B.Sc. degree in Chemistry cum laude in1973 from the University of Palermo. He was a full professor of Chemistry in the Department of Engineering, University ofPalermo, since 2000, and although he has now retired, he continues to carry out research. His scientific work mainly focuseson heterogeneous photocatalysis, such as preparation, characterization of many bulk and surface techniques, and testingof various types of bare and doped polycrystalline photocatalysts. He has collaborated with many scientists worldwide,producing joint papers in international journals (~350), many scientific and didactical books, and five patents. He is editorin-chief of the Journal of Photocatalysis and a member of the editorial boards of European Journal of Inorganic Chemistry,Current Organic Chemistry, International Journal of Photoenergy, Journal of Chemistry, and Journal of Membrane Science& Technology.
