The sustainability of energy and environment has been one of the most important concerns of the human society in recent years. Catalytic technologies play a major role in approaching the sustainable goal. In recent years, many friends visited Tianjin and brought to us exciting progress and presentations. Now, we propose to initiate an international symposium in Tianjin, the third largest, the richest in history and recently updated city in China, to host discussions on important catalytic topics. We propose to have the first event during October 8-10, 2014, just before the National Congress on Catalysis of China, which will be held in Hangzhou, so called paradise of China, the week afterwards.
