This Special Issue is related to studies of the hydrogen production from formic acid decomposition. It is based on five research papers and two reviews. The reviews discuss the liquid phase formic acid decomposition over bimetallic (PdAg), molecular (Ru, Ir, Fe, Co), and heterogenized molecular catalysts. The gas-phase reaction is studied over highly dispersed Pd, Pt, Au, Cu, and Ni supported catalysts. It is shown that the nature of the catalyst’s support plays an important role for the reaction. Thus, N-doping of the carbon support provides a significant promotional effect. One of the reasons for the high activity of the N-doped catalysts is the formation of single-atom active sites stabilized by pyridinic N species present in the support. It is demonstrated that carbon materials can be N-doped in different ways. It can be performed either directly from N-containing compounds during the carbon synthesis or by a post-synthetic deposition of N-containing compounds on the carbon support with known properties. The Issue could be useful for specialists in catalysis and nanomaterials as well as for graduate students studying chemistry and chemical engineering. The reported results can be applied for development of catalysts for the hydrogen production from different liquid organic hydrogen carriers.

Catalysts are made of nanoparticles of metals, metal oxides, and other compounds that may act as active phases, support the latter, or a combination of both. The initial incentive to reduce as much as possible, up to the nano-scale, the size of the particles of active catalyst components is to maximize the surface area exposed to reactants, thus minimizing the specific cost per function and increasing the rate of conversion of feedstocks to products in relatively simple reactions. Nowadays, the interest in nanocatalyst developments has shifted to an emphasis on improving the selectivity of catalysts, allowing one to obtain desirable reactions in more complex synthetic processes. Thus, new generations of nanocatalysts should be designed at the molecular level to display well-defined structural characteristics, in terms of size, shapes, hierarchical porosity, and morphologies, as well as with controlled chemical composition. The development of efficient nanocatalysts supposes the characterization of their various surface active sites at the nanometer scale, which is focused on establishing synthesis–structure–performance relationships.

Adequate quality of life and well-being of modern societies is only achievable with sustainable manufacturing processes that efficiently use raw materials, eliminate waste, and avoid the use of hazardous materials. All this is hardly conceivable without catalysis. In a world concerned with the exploitation of natural resources, catalysis can offer direct synthesis routes that maximize resource efficiency. The Iberoamerican society is far too significant and far too involved in global development, owing to its natural richness of resources, not to have an essential role in current developments and future directions. Catalysis, in the Iberoamerican academic and industrial communities, is recognized as a relevant scientific discipline that supports several strategic industrial sectors through the manufacturing of products and materials, and the operationalization of processes to produce energy and other utilities. As a reflection of this, once every two years the Iberoamerican Congress on Catalysis takes place to share and discuss the state-of-the-art of this discipline with the Federation of Iberoamerican Catalysis Societies. This book collected sixteen outstanding contributions, stemming from this exceptional event—one which will undoubtedly mark a turning point and could be a source of inspiration to all those involved in catalysis, particularly the young generation of competent researchers taking their first steps in this incredibly complex and beautiful discipline.
