Special Issue Information

Dear Colleagues,

Advanced functional nanocomposites play an important role in many fields of applications, such as catalysis, energy storage, adsorption techniques, ceramics, optoelectronics, sensing, etc. Therefore, the synthesis and characterization of advanced functional nanocomposites are gaining considerable attention from researchers. The crucial features of nanocomposite system allows combining the unique properties (optical, electronic, catalytic, magnetic, etc.) of individual components contained in nanocomposites. For example, the catalytic activities of nanoparticles and high surface area of the carbon matrix is seen as a promising solution for heterogeneous nanocomposite catalysts. Moreover, the utilization of nanocomposite structures in polymer chemistry leads to the improvement of important properties, such as their strength or resistance. In addition, the combination of semiconductor nanoparticles with conjugated polymers provides interesting nanocomposite systems with applications in optoelectronics. Recently, a carbonization of metal–organic frameworks (MOFs) was considered as an effective pathway for homogeneous nanocomposite production. Based on these, we would like to announce the Special Issue called “Synthesis of Advanced Nanocomposites with Catalytic and Electronic Properties” to contribute and expand the chemistry, properties, and applications of advanced nanocomposites. The scope of this issue covers the papers mainly focused on the processing of novel homogeneous nanocomposites applied in catalysis and electrochemistry.

This Special Issue on “Synthesis of Advanced Nanocomposites with Catalytic and Electronic Properties” aims to curate novel advances in the development and application of advanced nanocomposites. Topics include but are not limited to:

  • Novel techniques for preparation of advanced nanocomposites (e.g., single source precursor decomposition);
  • Synthesis and applications of nanocomposites based on metal/metal oxide nanoparticles and conjugated polymers;
  • Synthesis and applications of metal/metal oxide nanoparticle containing carbon-based nanocomposites;
  • Advanced optical and electronic properties of nanocomposites; and
  • Application of advanced nanocomposites in catalysis, energy storage, and optoelectronics.

Transition metal hydroxides have attracted a lot of attention as the electrode materials for supercapacitors owing to their relatively high theoretical capacity, low cost, and facile preparation methods. However, their low intrinsic conductivity deteriorates their high-rate performance and cycling stability. Here, self-supported sheets-on-wire CuO@Ni(OH)2/Zn(OH)2 (CuO@NiZn) composite nanowire arrays were successfully grown on copper foam. The CuO nanowire backbone provided enhanced structural stability and a highly efficient electron-conducting pathway from the active hydroxide nanosheets to the current collector. The resulting CuO@NiZn as the battery-type electrode for supercapacitor application delivered a high capacity of 306.2 mAh g−1 at a current density of 0.8 A g−1 and a very stable capacity of 195.1 mAh g−1 at 4 A g−1 for 10,000 charge–discharge cycles. Furthermore, a quasi-solid-state hybrid supercapacitor (qss HSC) was assembled with active carbon, exhibiting 125.3 mAh g−1 at 0.8 A g−1 and a capacity of 41.6 mAh g−1 at 4 A g−1 for 5000 charge–discharge cycles. Furthermore, the qss HSC was able to deliver a high energy density of about 116.0 Wh kg−1. Even at the highest power density of 7.8 kW kg−1, an energy density of 20.5 Wh kg−1 could still be obtained. Finally, 14 red light-emitting diodes were lit up by a single qss HSC at different bending states, showing good potential for flexible energy storage applications. Full article
