Prof. Minkee Choi from the Korea Advanced Institute of Science and Technology (KAIST) visited our group at Energy College Campus on July 14th. He delivered a lecture entitled "Separately Storing Electrons and Protons at Ru Particles and Base Promoters to Facilitate Ammonia Synthesis". This lecture provides crucial atomistic insights into the role of base promoters and offers significant perspectives for designing advanced NH3 synthesis catalysts. After the talk, he had in-depth discussions with the audience, and then visited the lab.
