2D Catalysts for Ammonia Synthesis at Room Temperature
Swinburne University of Technology, Australia
Ammonia is a basic chemical, widely used for modern fertilizer and industry. Its large-scaled production is based on the Haber-Bosch process at high temperature and high pressure, which is not energy-efficient. Electrochemical synthesis of ammonia from air and water can deliver a clean and green option. This talk is to introduce 2D catalysts for ammonia synthesis at room temperature, with a focus on the computational screening and design of novel catalysts. Catalysts are evaluated based on theoretical calculations of the Gibbs free energy changes of the elementary steps associated with nitrogen reduction reaction. As presented, 2D carbides and nitrides are identified as high performance catalysts for this reaction.
Dr Chenghua Sun obtained his PhD in 2007, from Institute of Metal Research, Chinese Academy of Science, under the supervision of Prof. Hui-Ming Cheng, Prof. Max Lu and Prof. Feng Li. Then he joined the University of Queensland as a postdoctoral fellow, and obtained the Research Excellence Award in 2012. In 2013, Dr Sun joined Monash University as a lecturer, and later he was awarded the Future Fellowship in 2014. Now Dr Sun is an associate Professor in Swinburne University of Technology, Australia. He is working on computer-aided design of catalysts for clean energy and environment.
