Special Issue Information

Dear Colleagues,

The development of green, sustainable chemical processes striving for waste reduction, atomic efficiency, and high rates of catalyst recovery is one of the vital challenges in the chemical industry. The classical procedures for organic transformations have their inherent drawbacks, such as the use of toxic and hazardous reagents and solvents, harsh reaction conditions, and the production of great amounts of toxic waste. Alternatively, nanostructured materials are attractive candidates as heterogeneous catalysts for various organic transformations, especially because they meet green chemistry principles.

Recently, extensive efforts have been devoted to the rational design and fabrication of highly active and selective nanostructured catalysts for thermocatalysis or photocatalysis organic transformation processes. The ease of isolation and separation of the heterogeneous catalysts from the desired organic product and the recovery and reuse of these catalysts further enhance their attractiveness as green and sustainable catalysts.

This Special Issue will present recent and significant developments in the design, preparation, and application of heterogeneous catalysts towards various organic transformations. Original articles and short reviews are welcome for submission.

The exploitation of highly efficient solvent-free catalytic systems for the selective aerobic oxidation of benzylic compounds to produce corresponding ketones with molecular oxygen under mild conditions remains a great challenge in the chemical industry. In this work, Au-Pd nanoparticles supported on porous carbon catalysts were fabricated by the borax-mediated hydrothermal carbonization method and the chemical reduction method. The physicochemical properties of Au-Pd bimetallic samples were examined by XRD, N2 sorption, SEM, TEM, and XPS techniques. The Au-Pd nanoparticles have successfully immobilized on the spherical carbon support with a porous structure and large surface area. A solvent-free catalytic oxidation system was constructed to selectively convert indane into indanone with Au-Pd nanocatalysts and O2. In contrast with a monometallic Au or Pd catalyst, the resulting bimetallic Au-Pd catalyst could effectively activate O2 and exhibit improved catalytic activity in the controlled oxidation of indane into indanone under 1 bar O2. A total of 78% conversion and >99% selectivity toward indanone can be achieved under optimized conditions. The synergistic effect of Au and Pd and porous carbon support contributed to the high catalytic activity for aerobic benzylic compound oxidation. This work offers a promising application prospect of efficient and recyclable Au-Pd nanocatalysts in functional benzylic ketone production. Full article

Para-dioxanone, a typical monomer for high-performance biomedical polymers, is generally obtained from the catalytic dehydrogenation of diethylene glycol. In this work, Cu/SiO2 catalysts were prepared by two different methods and applied in diethylene glycol dehydrogenation. The effects of catalyst properties on the performance of para-dioxanone production were systematically explored by combined techniques. The results showed that the high specific surface area and regular pore structure of the catalyst promoted and stabilized the high dispersion of the copper species with an abundant Cu-Si interface, thereby providing numerous reactive sites. The appropriate Cu0/Cu+ ratio in the active components produced efficient synergy, which was responsible for the excellent dehydrogenation performance. In addition, the low surface acid density (0.532 μmol/m2) of the catalyst greatly reduced the occurrence of diethylene glycol dehydration, thus improving para-dioxanone selectivity over 90% with promising stability.
