个人简介

Masaaki Kitano studied chemical engineering and received his Ph.D. degree from Osaka Prefecture University in 2006. After a stint with Prof. Michikazu Hara as a postdoctoral research fellow at Kanagawa Academy of Science and Technology, he joined the Tokyo Institute of Technology in 2009 as an assistant professor and was promoted to associate professor in 2013. From 2023, he became a professor of Tokyo Institute of Technology. His current research focuses on the design, synthesis, and characterization of electride, hydride, and nitride-based catalysts for ammonia synthesis and other hydrogenation reactions, synthesis of alloy nanoparticles, and solid acid catalysts. He has published over 142 research articles in top-level journals with more than 10426 citations (Web of Science, H-index: 52).

报告摘要

We have recently reported that electride and hydride materials promote the activity of transition metal catalysts significantly at low reaction temperatures, which demonstrates the essential role of hydride (H-) ion in low-temperature ammonia synthesis. These materials have very low work function because of the formation of anionic electrons at anion vacancy sites. We have further demonstrated that ammonia synthesis can be significantly promoted by using lattice anions as active sites for N2 dissociation. In this case, nitride-based materials such as BaCeO3-xNyHz and LaN work as efficient catalyst supports for transition metal catalysts. In this lecture, I will introduce the development of novel inorganic materials with various anions such as e-, H-, and N3- and their application to ammonia synthesis and decomposition and other chemical reactions.
