Special Issue Information

Dear Colleagues,

It is well known that more than 90% of commercial chemical products involve catalytic processes in at least one step of their manufacture. Despite the ubiquitous use of catalytic processes, further demand for energy sources, chemical building blocks, fine chemicals, food processing and waste treatment (exhaust gases, wastewaters, solid wastes) is pushing material scientists and chemical engineers to develop new catalyst materials and corresponding processes. Primarily, catalyst evolution reflects in higher activity and long-term stability of materials, as well as in higher selectivity of catalysts towards desired products.

Some of the greatest technological challenges of a mankind involve the development of novel catalytic processes, specifically:

  • The valorization of captured CO2 into platform chemicals and energy vectors;
  • The valorization of CH4 that is commonly flared at small or temporary sources;
  • The valorization of biomass to yield value-added chemicals;
  • Environmental pollution abatement;
  • Fuel-cells (oxygen evolution and reduction reactions);
  • Enzymatic conversions.

This Special Issue will feature articles that cover topics related to materials preparation, engineering, functionalization, activation and characterization of materials, and particularly, experimental and theoretical investigations of their themo-, photo-, electro-, bio- or organocatalytic activity. Material science and chemical engineering nexus is particularly encouraged.

We invite you to submit review articles, original research papers and communications for this Special Issue before the end of January 2020.

An effective method for levulinic acid esters synthesis by the enzymatic Fischer esterification of levulinic acid using a lipase B from Candida antarctica (CALB) immobilized on the advanced material consisting of multi-wall carbon nanotubes (MWCNTs) and a hydrophobic polymer—polytetrafluoroethylene (Teflon, PTFE)—as a heterogeneous biocatalyst, was developed. An active phase of the biocatalyst was obtained by immobilization via interfacial activation on the surface of the hybrid material MWCNTs/PTFE (immobilization yield: 6%, activity of CALB: 5000 U∙L∙kg−1, enzyme loading: 22.5 wt.%). The catalytic activity of the obtained biocatalyst and the effects of the selected reaction parameters, including the agitation speed, the amount of PTFE in the CALB/MWCNT-PTFE biocatalyst, the amount of CALB/MWCNT-PTFE, the type of organic solvent, n-butanol excess, were tested in the esterification of levulinic acid by n-butanol. The results showed that the use of a two-fold excess of levulinic acid to n-butanol, 22.5 wt.% of CALB on MWCNT-PTFE (0.10 wt.%) and cyclohexane as a solvent at 20 °C allowed one to obtain n-butyl levulinate with a high yield (99%) and selectivity (>99%) after 45 min. The catalyst retained its activity and stability after three cycles, and then started to lose activity until dropping to a 69% yield of ester in the sixth reaction run. The presented method has opened the new possibilities for environmentally friendly synthesis of levulinate esters. Full article
