Special Issue Information

Dear Colleagues,

Over the last few decades, increasing number of researches have focused on design and synthesis of heterogeneous catalysts, since over 90% of industrial processes for chemical synthesis use heterogeneous systems. In comparison with traditional homogeneous catalysts, heterogeneous catalysts are quite stable and easy to separate from the reaction system. However, due to the multiple components of heterogeneous systems, the  reactivity and selectivity of catalysts are sometimes low. Presently, heterogeneous catalyst have been widely used in various types of catalytic process, including thermocatalysis, electro-catalysis, photocatalysis and biocatalysis. Given the widespread use of heterogeneous catalysts and the growing needs of environmental protection and green chemistry, it is necessary to develop good-to-excellent catalysts for various reactions and investigate how heterogeneous catalysts work with good performacens.  

This Special Issue will cover topics including, but not restricted to, the recent advances in heterogeneous catalysis for new energy catalysis, biomass transformation and fine chemicals synthesis by using supported metal catalysts or mixed metal oxides. Short communications, full research articles and review articles are all respectfully welcomed to submit in the Specisl Issue.

Recovered carbon blacks (rCBs) produced from end-of-life tires using pyrolysis were transformed into solid acid catalysts for the synthesis of acetins, i.e., products with a wide spectrum of practical applications. Tuning the chemical properties of the surface of samples and introducing specific functional groups on the rCBs were achieved through carbon functionalization with concentrated H2SO4. The initial and modified rCBs were thoroughly characterized using techniques such as elemental analysis, potentiometric back titration, thermogravimetric technique, scanning and transmission microscopy, X-ray photoelectron spectroscopy, etc. The catalytic activities of the samples were measured via batch mode glycerol acetylation performed at 110 °C and compared to the catalytic performance of the functionalized commercial carbon black. The modified rCBs were found to show a significant catalytic effect in the tested reaction, giving high glycerol conversions (above 95%) and satisfactory combined yields of diacetins and triacetin (~72%) within 4 h; this behavior was attributed to the presence of -SO3H moieties on the surface of functionalized rCBs. The reusability tests indicated that the modified samples were catalytically stable in subsequent acetylation runs. The obtained results evidenced the feasibility of using end-of-life tires for the production of effective acid catalysts for glycerol valorization processes. Full article
