Special Issue Information

Dear Colleagues,

We invite you to contribute to a new Special Issue entitled “Novel Two-Dimensional Energy-Environmental Materials”, which seeks to explore the latest developments and applications of 2D materials and their heterostructures in the fields of energy generation and environmental conservation.

As the global demand for sustainable energy solutions and environmental stewardship continues to grow, 2D materials and their heterostructures offer new avenues for addressing these pressing challenges. Due to the advantages of ultralow thickness, high strength, high conductivity, tunable electronic structures, and large surface-to-volume ratio, 2D materials and 2D heterostructures exhibit tremendous potential in energy conversion, energy storage, environmental protection, and pollution treatment. These advancements contribute significantly to a greener and more environmentally friendly future, while also opening new avenues for innovative applications that utilize the distinct benefits of 2D materials and their heterostructures. This Special Issue focuses on original research papers and reviews about the design and synthesis of novel 2D materials and 2D heterostructures, highlighting their applications and significant progress in the areas of energy conversion, energy storage, environmental protection, and pollution treatment.

This Research Topic includes, but is not limited to, the following:

  • Innovative synthesis and characterization of 2D materials and heterostructures.
  • Energy conversion and storage applications of 2D materials and heterostructures.
  • Environmental remediation and pollution control with 2D materials and heterostructures.
  • Theoretical modeling and computational studies of 2D materials and heterostructures.
  • Performance optimization of 2D m
  • Environmental stability of 2D materials and heterostructures.
  • Sensing applications of 2D materials.

Abstract
In recent years, the photoelectric conversion efficiency of three–dimensional (3D) perovskites has seen significant improvements. However, the commercial application of 3D perovskites is hindered by stability issues and the toxicity of lead. Two–dimensional (2D) perovskites exhibit good stability but suffer from low efficiency.

In recent years, the photoelectric conversion efficiency of three–dimensional (3D) perovskites has seen significant improvements. However, the commercial application of 3D perovskites is hindered by stability issues and the toxicity of lead. Two–dimensional (2D) perovskites exhibit good stability but suffer from low efficiency. Designing efficient and stable lead–free 2D perovskite materials remains a crucial unsolved scientific challenge. This study, through structural prediction combined with first–principles calculations, successfully predicts a 2D perovskite, CsTeI5. Theoretical calculations indicate that this compound possesses excellent stability and a theoretical efficiency of up to 29.3%, showing promise for successful application in thin–film solar cells. This research provides a new perspective for the design of efficient and stable lead-free 2D perovskites. Full article

Spin-gapless semiconductor (SGS), a class of zero-gap materials with fully spin-polarized electrons and holes, offers significant potential for high-speed, low-energy consumption applications in spintronics, electronics, and optoelectronics. Our first-principles calculations revealed that the Pca21 C4N3 monolayer exhibits a ferromagnetic ground state. Its band structure displays SGS-like characteristics, with the energy gap between the valence and conduction bands near the Fermi level in the spin-down channel much smaller than the one in the other spin channel. To enhance its SGS properties, we introduced electrons into the Pca21 C4N3 monolayer by adsorbing the CO gas molecule on its surface. Stable gas adsorption (CO@C4N3) effectively narrowed the band gap in the spin-down channel without changing the band gap in the spin-up channel obviously. Moreover, injecting holes into the CO@C4N3 system could increase the net magnetic moments and induce an SGS-to-metallic phase transition, while injecting electrons into the CO@C4N3 system is able to lower the net magnetic moments and cause an SGS-to-half-metallic phase transition. Our findings not only underscore a new promising material for practical metal-free spintronics applications but also illustrate a viable pathway for designing SGSs. Full article
