It is our great pleasure to announce that the International Symposium on Single-atom Catalysis (ISSAC) will be held at Dalian, China, from June 30 to July 2, 2016. This symposium is a satellite pre-symposium of the 16th International Congress on Catalysis (ICC 16) which will be held from July 3 to 8, 2016, in Beijing, China. As a new frontier of heterogeneous catalysis, single-atom catalysis (SAC) has attracted considerable attention in the past years, with the rapid development of new preparation methods, advanced characterization techniques, and insightful theoretical understanding at the single-atom scale. This symposium will provide an international forum for active researchers in the field of single-atom catalysis to discuss the new results and ideas.
