The main aim of this Marie-Curie ETN is to instruct a new generation of scientists who will bring innovation in the field of electrocatalysis with particular emphasis on the design of new nanomaterials and processes based on Cu/M bimetallic compounds with improved selectivity and efficiency towards CO2 reduction to value-added products (CO, HCOOH and C2H4). The ECOMATES network gathers large European universities, international research laboratories (VITO, and IIT in the area of sustainable development), the ESRF (an international European facility), and two SMEs (ADVENT, for innovation in MEA preparation, and APRIA, for the design of testing of a CO2 electrolyzer).
