报告人简介：Bin Liu received his bachelor of engineering (1st Class Honours) and master of engineering degrees at the National University of Singapore, Singapore in 2002 and 2004, respectively, and completed his doctoral degree at the University of Minnesota, USA in 2011. After spending a year as postdoctoral fellow in the University of California Berkeley, USA, he joined School of Chemical and Biomedical Engineering at Nanyang Technological University as an Assistant Professor in June 2012 and was promoted to Associate Professor in March 2017. In February 2023, Professor Liu joined the Department of Materials Science and Engineering at City University of Hong Kong as a Professor. His research focuses on photo(electro)catalysis and in-situ/operando characterization. Professor Liu was awarded emerging investigator by Journal of Materials Chemistry A, Royal Society of Chemistry in 2016, class of influential researchers by Industrial & Engineering Chemistry Research, American Chemical Society in 2018, and listed in the “Highly Cited Researchers” in Cross-Field in 2019 and Chemistry in 2020-2022 by Clarivate Analytics.

报告简介：Electrocatalytic hydrogenation enables the efficient treatment of oxidized contaminants in water under mild conditions, but its application has been greatly hindered by the need for a supporting electrolyte and the large amounts of unsafe intermediate products. In this talk, I am going to present the development of a rhodium nanoparticle-modified palladium membrane electrochemical reactor (Rh NPs-PdMER) for the hydrogenation of oxidized contaminants in drinking water and industrial effluents. The Rh NPs-PdMER not only enabled the hydrogenation of 12 different oxidized contaminants to safe products with ≥99% conversion and ≥95% yield in water without a supporting electrolyte, but also required a very low operating voltage of only 1.4 V. The performance of the Rh NPs-PdMER can be attributed to the specific reactor configuration and the unique adsorbability of the hydrogenated intermediates of the oxidized contaminants to the Rh nanoparticles.
