Special Issue Information
Dear Colleagues,
A great challenge in the field of catalysis is the synthesis of catalysts with enhanced catalytic activity, selectivity, and durability. The structural and compositional complexity of the catalytic system requires a strong systematic approach to elucidate the nature of the catalyst’s active sites. A catalytic active site is a mono- or polyatomic entity with a specific electronic surface configuration, able to generate a catalytic act (adsorption, dissociation of reactant molecules, and desorption of reaction products).
In-depth knowledge of the composition, structure, and nature of active sites provides the possibility of tailoring the catalytic properties in order to improve catalytic performance (activity and selectivity). Such properties that can be targeted by synthesis are controlled porosity, sintering, resistance, large specific surface area, optimal acid–base properties, lattice vacancies, metal–support interaction, catalyst design, conductivity, etc.
Therefore, the change in catalyst properties leads to modified kinetic parameters (reaction rate, activation energy) and the reaction mechanism.
Improving catalytic performance by modifying catalysts should play an important role in the current global situation by reducing the negative impact on the environment and supporting the sustainable use of natural resources.
The purpose of this issue is to present state-of-the-art strategies for modifying catalysts, aiming to provide an important contribution to the development of research in this area from both practical and theoretical perspectives.
We aim to gain a better understanding of catalytic systems, facilitating the establishment of correlations between composition and physical–chemical properties and performance.
