Ceramic proton conductors for natural gas, hydrogen, and ammonia
Date: 2020/11/04 - 2020/11/04
Academic Seminar: Ceramic proton conductors for natural gas, hydrogen, and ammonia
Speaker: Prof. Truls Norby, University of Oslo
Time: 14:00pm-15:30, Nov 4, 2020 (Wednesday)
Location: Room 454, Long Bin Building, Shanghai Jiao Tong University Minhang Campus
Abstract
Ceramic proton conductors based on acceptor-doped barium zirconate perovskites offer potential unique process advantages over solid oxide or polymer alternatives for natural gas conversion, hydrogen production, and ammonia. Tubular designs are established, but development towards planar stacks is ongoing. Materials challenges connected to conductivity, thermal expansion, and electrode kinetics will be discussed briefly.
Biography
Truls Norby (b. 1955) has his PhD from the University of Oslo (UiO) 1986, where he studied and worked with late prof. Per Kofstad. Norby became professor at the Department of Chemistry 1994 and head of the Group for Solid-State Electrochemistry in 1997, now Group for Electrochemistry, which is part of the Centre for Materials Science and Nanotechnology (SMN) at UiO.
Norby works with thermodynamics and transport of defects in materials for solid-state fuel cells, electrolysers, batteries, gas separation membranes, sensors, and metal protection oxide layers. He specialises in protons in oxides and their use in high temperature proton conductors and hydrogen separation membranes. Recently, he also focuses on topics related to transport in adsorbed layers on surfaces and across interfaces (grain boundaries, electrodes) and on the semiconducting properties of oxides for uses in photoelectrochemistry and thermoelectrics.
He has published more than 270 journal papers, graduated near 100 Master- and PhD-students, and is editor of Solid State Ionics and President of the International Society for Solid State Ionics (ISSE) 2019-2021. He is member of the Norwegian Academy of Science and Letters and other national academies. He has won the UiO Innovation Prize (2012) and the Norwegian Guldberg-Waage medal for chemistry 2018.
He has founded companies NORECS AS (2001) which develops, manufactures, and sells test equipment world-wide (including China) and Protia AS (now CoorsTek Membrane Sciences AS) (2007) which develops energy conversion processes using proton conducting ceramic materials. From 2020 he is established also in Jiangsu, China, as guest professor at Soochow University and Jiangyin NorEn Material Technology Co., Ltd.
