202447 citationsOpen accessTshwane University of Technology

In plain language

Borophene is a monolayer boron nanosheet characterised by distinct structural, electronic, mechanical, and thermal features. Multiple fabrication routes exist for its production, ranging from molecular beam epitaxy and chemical vapour deposition to chemical techniques including ultrasonic exfoliation and the thermal decomposition of boron-containing precursors. The material displays highly adjustable characteristics, allowing for bandgap engineering, plasmonic behaviour, and tailored thermal conductivity. In terms of functional use, borophene shows substantial promise within the energy storage sector. It is especially relevant as an anode material for metal-ion batteries and supercapacitors, while also presenting opportunities in alternative energy systems like sodium-oxygen batteries. Consolidating these synthesis methods, physical behaviours, and prospective storage integrations offers critical guidance for continuing development across nanomaterials science.

Key takeaways

  • Borophene can be synthesised using molecular beam epitaxy, chemical vapour deposition, ultrasonic exfoliation, and thermal decomposition of precursors.
  • The material exhibits tunable electronic, mechanical, and thermal properties, enabling bandgap engineering and plasmonic control.
  • Borophene serves as a prospective anode material for both metal-ion batteries and supercapacitors.
  • Emerging energy storage systems such as sodium-oxygen batteries represent additional potential avenues for borophene integration.

Why it matters

Energy storage technologies require new materials that deliver higher performance and versatility. Borophene offers highly adaptable electronic, mechanical, and thermal characteristics that can improve next-generation batteries and supercapacitors. Understanding how to manufacture and manipulate this monolayer material aids the development of more efficient, durable energy storage solutions across portable electronics and grid systems.

Commercialisation angle

Target applications focus on energy storage hardware, specifically anodes for metal-ion batteries, supercapacitors, and sodium-oxygen systems. Intended users include battery manufacturers, energy storage developers, and nanomaterial producers. Because the abstract outlines synthetic strategies, tunable properties, and prospective uses within a review format, this technology remains at an early stage of laboratory research and development rather than near-market deployment.

Abstract

Monolayer boron nanosheet, commonly known as borophene, has garnered significant attention in recent years due to its unique structural, electronic, mechanical, and thermal properties. This review paper provides a comprehensive overview of the advancements in the synthetic strategies, tunable properties, and prospective applications of borophene, specifically focusing on its potential in energy storage devices. The review begins by discussing the various synthesis techniques for borophene, including molecular beam epitaxy (MBE), chemical vapor deposition (CVD), and chemical methods, such as ultrasonic exfoliation and thermal decomposition of boron-containing precursors. The tunable properties of borophene, including its electronic, mechanical, and thermal characteristics, are extensively reviewed, with discussions on its bandgap engineering, plasmonic behavior, and thermal conductivity. Moreover, the potential applications of borophene in energy storage devices, particularly as anode materials in metal-ion batteries and supercapacitors, along with its prospects in other energy storage systems, such as sodium-oxygen batteries, are succinctly, discussed. Hence, this review provides valuable insights into the synthesis, properties, and applications of borophene, offering much-desired guidance for further research and development in this promising area of nanomaterials science.
