Special Issue Information

Dear Colleagues,

We are pleased to announce the upcoming Special Issue of Materials on "Research on High-Efficiency Catalytic Materials for Energy and Environment". This SI aims to highlight recent advances and innovations in catalytic materials for applications in energy conversion and environmental protection.

The use of efficient catalytic materials plays a crucial role in addressing the global challenges of energy production and environmental sustainability. In this context, we aim to focus on the development and characterization of high-efficiency catalytic materials for various energy and environmental applications.

Key topics of interest for this Special Issue include, but are not limited to:

  • Novel synthesis methods and techniques for the preparation of catalytic materials;
  • Catalytic materials for energy conversion processes, such as fuel cells, solar cells, and hydrogen production;
  • Catalytic materials for environmental applications, including pollution abatement, wastewater treatment, and air purification;
  • Advanced characterization techniques for understanding the structure-property relationships of catalytic materials;
  • Computational modeling and simulation of catalytic processes and materials
  • High-performance catalyst design and optimization strategies;
  • Sustainable and eco-friendly approaches for catalyst synthesis and manufacturing.

By exploring these topics, we hope to accelerate the development of high-performance catalytic materials that can address the current energy and environmental challenges.

Researchers are encouraged to submit original research papers, reviews, and communications that contribute to this important and timely field. Thank you for your consideration.

Polyanionic structures, (MO4)n−, can be beneficial to the transport of lithium ions by virtue of the open three-dimensional frame structure. However, an unstable interface suppresses the life of the (MO4)n−-based anode. In this study, MnWO4@C nanorods with dense nanocavities have been synthesized through a hydrothermal route, followed by a chemical deposition method. As a result, the MnWO4@C anode exhibits better cycle and rate performance than MnWO4 as a Li-ion battery; the capacity is maintained at 718 mAh g−1 at 1000 mA g−1 after 400 cycles because the transport of lithium ions and the contribution of pseudo-capacitance are increased. Generally, benefiting from the carbon shell and electrolyte additive (e.g., FEC), the cycle performance of the MnWO4@C electrode is also effectively improved for lithium storage. Full article

Hydrogen peroxide (H2O2) is a high-demand chemical, valued as a powerful and eco-friendly oxidant for various industrial applications. The traditional industrial method for producing H2O2, known as the anthraquinone process, is both costly and environmentally problematic. Electrochemical synthesis, which produces H2O2 using electricity, offers a sustainable alternative, particularly suited for small-scale, continuous on-site H2O2 generation due to the portability of electrocatalytic devices. For efficient H2O2 electrosynthesis, electrocatalysts must exhibit high selectivity, activity, and stability for the two-electron pathway-oxygen reduction reaction (2e ORR). Transition-metal chalcogenide (TMC)-based materials have emerged as promising candidates for effective 2e ORR due to their high activity in acidic environments and the abundance of their constituent elements. This review examines the potential of TMC-based catalysts in H2O2 electrosynthesis, categorizing them into noble-metal and non-noble-metal chalcogenides. It underscores the importance of achieving high selectivity, activity, and stability in 2e ORR. By reviewing recent advancements and identifying key challenges, this review provides valuable insights into the development of TMC-based electrocatalysts for sustainable H2O2 production.
