The increase global energy demand and environment impact of traditional energy resources poses serious challenge to human health, energy secure, and environment protection. During the recent 2015 United Nations conference on climate change in Paris (COP 21), 195 member states have signed the deal that is designed to limit greenhouse gas emissions and prevent an average global temperature increase of 2 degrees Celsius above pre-industrial times. In this context, electrocatalysis has attracted tremendous attention worldwide as a sustainable and efficient energy system. Promising applications of electrocatalysis for energy storage and conversion are electrolysis, fuel cells, metal/air batteries, and CO2 conversion. Both technologies play crucial role in the future sustainable societies. Thus, huge research efforts have been dedicated to improving the electrochemical reactions involved in these technologies. The main training objective of Euro-NANOCAT is the improvement of the career perspectives of young researchers, including their inter-sectoral employability, by training them at the forefront of research in the field of non-precious and earth abundant electrocatalysts for CO2, oxygen and hydrogen evolutions. We will focus on some important reactions for valorization of CO2, energy storage, and hydrogen economy: oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), hydrogen reduction reaction (HRR), and CO2 conversion reactions. In particular, we will investigate: noble metal-free catalysts, heart abundant-based catalysts, nanostructured interface, nanomaterials, and carbocatalysts. Euro-NANOCAT aims to be the first integrated training program within Innovative Training Networks – European Training Networks in the area of non-precious and earth abundant electrocatalyst nanostructured materials by combining “Knowledge Triangle” and "Energy Triangle" approaches. We consider applying MSCA-ITN-2017: Innovative Training Networks – European Training Networks, deadline of 10th January 2017, in which we will request a budget about 3,186 k€ corresponding to 540 researcher-months. It corresponds to 15 Early-Stage Reseachers (ESRs) during 36 months.
