Special Issue Information

Dear Colleagues,

Catalysis is a fascinating phenomenon not only in natural processes but also in chemical ones. About 90% of the chemical industry technologies involve catalysts. The importance of catalysis also highlights the fact that one of the principles of green chemistry is devoted exclusively to this issue. Catalysis is a powerful tool in designing of sustainable, energy- and material-efficient and clean technologies

Important problems facing catalyst designers include understanding the factors affecting the activity of homogenous and heterogeneous catalysts, as well as developing catalysts with readily available active centers for reactants and stable under the process conditions.

Currently, the key challenge for the organic synthesis is the development of new catalysts that characterize both high activity and selectivity, and would ensure their easy separation from the reaction mixture. The removal of the catalyst after reaction is usually cost-intensive and energy-consuming. Therefore, two-way actions are being taken:

  1. improvement of existing separation techniques and introduction of new, more energy-saving techniques
  2. the use of heterogeneous catalysts. Such catalysts create the possibility of their effective recycling. Moreover, they can be used in flow reactors.

This Special Issue aims to collect both original research articles and reviews focusing, though not exclusively, on:

  • The application of heterogeneous and homogenous catalysis in organic synthesis;
  • Synthesis and characterization of new catalysts;
  • Designing of new methods of catalytic synthesis of organic compounds, meeting the requirements of sustainable development and principles of green chemistry.
  • Designing of immobilized catalyst on solid carriers such as polymers, carbon nanomaterials, silica, hybrid supports and others;

Ethylene glycol is regarded as a promising C2 platform molecule due to the fast development of its production from sustainable biomass. This study inquired the structural requirements of Co-based catalysts for the liquid-phase ammonolysis of ethylene glycol to value-added ethanolamine. We showed that the rate and selectivity of ethylene glycol ammonolysis on γ-Al2O3-supported Co catalysts were strongly affected by the metal particle size within the range of 2–10 nm, among which Co nanoparticles of ~4 nm exhibited both the highest ethanolamine selectivity and the highest ammonolysis rate based on the total Co content. Doping of a moderate amount of Ag further promoted the catalytic activity without affecting the selectivity. Combined kinetic and infrared spectroscopic assessments unveiled that the addition of Ag significantly destabilized the adsorbed NH3 on the Co surface, which would otherwise be strongly bound to the active sites and inhibit the rate-determining dehydrogenation step of ethylene glycol.
