EUROPACAT 2017 is the APP related to the 13th European Congress on Catalysis that will be held from August 27 to 31, 2017 in Florence, Italy. The conference, a major event in the area of catalysis and with the theme of “A bridge to the future”, features the crucial roles of catalysis science and technology in enabling our sustainable future. The conference, the main biannual event for catalysis in Europe under the auspices of EFCATS (the European Federation of Catalysis Societies), is organized by ERIC aisbl (European Research Institute of Catalysis) and the Italian Group of Catalysis of the Italian Chemical Society (SCI), in collaboration with the Division of Industrial Chemistry of SCI and the University Consortium on Science and Technology of Materials (INSTM). The conference offers both the state-of-the-art on catalysis research and, more importantly, a perspective of new trends and opportunities for catalysis in the next decades.
