Energy, Environment and Biomedical Applications of Boron Nitride and Boron Nitride Carbon Nanotubes: A Sustainable Industrial Scale-Up Exegesis

Boron-Nitride Nanotubes (BNNTs) are electrical insulators that usually have higher thermal and chemical properties than Carbon Nanotubes. Some of the most exceptional stiffness are shown by BNNTs, which shows potential applications in polymeric composites and ceramics. Such high stiffness also leads to lighter, more affordable, and faster transportation applications for lightweight ballistic armor and applications. When considering BNNTs' possible uses, focusing on their thermal and oxidative stability and their chemical inertness is essential. These properties can be logically used in capsules in which we have to protect nanomaterials that are unstable in the air or can be contaminated easily at standard atmosphere. This study discusses about the current trends, sustainable elucidation of synthesis methods, and prospective applications of boron nitride nanotubes. Through recent advancements, many new technologies are used in synthesizing and applying BNNTs and boron-nitride carbon nanotubes, giving higher yields and keeping the unique properties shown intact which align with the current United Nations Sustainable Development Goals. A balanced approach has been followed in the review to cover all the significant challenges, opportunities and economics of various industry-based production and application models associated with the BNNTs towards carbon neutrality.
