Abstract

Noble metals have long been central to catalysis, especially due to their higher reactivity compared to catalysts based on Earth-abundant transition metals. The efficacy of Earth-abundant metal catalysts was already shown at the beginning of the 20th century with the Fe-catalyzed Haber-Bosch process of ammonia synthesis and later in the Fischer-Tropsch reaction. Nanoscience revolutionized catalyst preparation methodologies, and was generally more focused on noble metal nanoparticles, which are remarkably efficient. The focus of both homogeneous and heterogeneous catalysis has changed to the study and methodologies to increase the activity of abundant transition metals including Mn, Fe, Co, Ni, Cu and their nanocomposites. The evolution of chemical industries and the development of green chemistry has increased the demand for more efficient, economically profitable and abundant catalysts. The research project aims to develop strategies to increase the reactivity of metal nanoparticles for hydrogenations, through the concept of cooperative catalysis and frustrated Lewis pairs. The strategy is a paradigma change in heterogenous catalysis and refers to the cooperative action of ligands together with a metallic surface to give an heterolytic H2 cleavage mechanism, for its activation. With this, new reaction pathways are created, with lower energy barriers, for transformations in milder conditions. Studies with gold catalysts, which showed great selectivity in the hydrogenation reactions, will be used as the basis for the intended studies. (AU)
