Special Issue Information

Dear Colleagues,

Due to the excessive fossil fuel consumptions, climate change caused by global warming has been increasingly a threat to our life, with weather conditions such as drought, floods, heat waves, heavy rain and landslides becoming more frequent. Some other serious consequences of global warming include rising sea levels, ocean acidification and loss of biodiversity. In order to limit global warming to 1.5 degrees Celsius, carbon neutrality by mid-21st century is essential, which is the target set in the Paris agreement signed by 195 countries.

This topic of the special issue of Nanomaterials is “Nanostructured Materials for Carbon Neutrality“, mainly focused on the design, synthesis/fabrications, and computational/theoretical studies of nanostructured materials for carbon neutrality. This special issue particularly welcomes experimental and theoretical work of interdisciplinary nature across basic science and engineering disciplines. The areas include but are not limited to nanostructured materials and composites for:

  • Novel carbon neutral science and technology to reduce the greenhouse gas emissions;
  • Renewable energy technology to replace fossil-fuel consumptions;
  • Carbon capture, storage, and utilization;
  • Electrocatalytical/photocatalytical CO2 reduction reactions (CO2RR);
  • Novel Nitrogen reduction reactions (NRR) at ambient condition, oxygen reduction reactions (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER);
  • Rechargable battery materials including electrolytes, electodes, and separators.

Porous C nanosheet/Cu2S composites were prepared using a simple self-template method and vulcanization process. The Cu2S nanoparticles with an average diameter of 140 nm are uniformly distributed on porous carbon nanosheets. When used as the anode of a potassium-ion battery, porous C nanosheet/Cu2S composites exhibit good rate performance and cycle performance (363 mAh g−1 at 0.1 A g−1 after 100 cycles; 120 mAh g−1 at 5 A g−1 after 1000 cycles). The excellent electrochemical performance of porous C nanosheet/Cu2S composites can be ascribed to their unique structure, which can restrain the volume change of Cu2S during the charge/discharge processes, increase the contact area between the electrode and the electrolyte, and improve the electron/ionic conductivity of the electrode material.

Artificial photosynthesis is promising to convert solar energy and CO2 into valuable chemicals, and to alleviate the problems of the greenhouse effect and the climate change crisis. Here, we fabricated a novel photocatalyst by directly growing Bi2MoO6 nanosheets on three-dimensional (3D) N,O-doped carbon (NO-C). Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) show that the designed photocatalyst ensured the close contact between Bi2MoO6 and NO-C, and reduced the stacking of the NO-C layers to provide abundant channels for the diffusion of CO2, while NO-C can allow for fast electron transfer. The charge transfer in this composite was determined to follow a step-scheme mechanism, which not only facilitates the separation of charge carriers but also retains a strong redox capability. Benefiting from this unique 3D structure and the synergistic effect, BMO/NO-C showed excellent performance in photocatalytic CO2 reductions. The yields of the best BMO/NO-C catalysts for CH4 and CO were 9.14 and 14.49 μmol g−1 h−1, respectively. This work provides new insights into constructing step-scheme photocatalytic systems with the 3D nanostructures. Full article
