Researchers at the University of Surrey have made a significant breakthrough in understanding the growth process of Hexagonal Boron Nitride (hBN), a remarkable 2D material known for its resilience and adaptability. This ultra-thin material, often referred to as 'white graphene,' has the potential to revolutionize various industries. The study, published in Small, unveils a new 'nanoporous' form of hBN, which offers structured voids enabling selective absorption, advanced catalysis, and enhanced functionality. This discovery greatly expands the material's environmental applications, making it useful for detecting and filtering pollutants, as well as for advancing energy systems such as hydrogen storage and fuel cell catalysts. Collaborating with Graz University of Technology, the research team conducted in-depth investigations into the growth process of hBN using cutting-edge modeling techniques. By analyzing key molecular processes, they developed an atomic-scale model to guide the material's growth with precision at any temperature. The theoretical simulations aligned closely with experimental observations, promising controlled and superior production of hBN with tailored designs and functionalities. Dr. Marco Sacchi, the lead author of the study, emphasized the importance of understanding the atomic-scale processes that govern the formation of hBN and its nanostructures. This knowledge allows for the engineering of materials with unprecedented precision, optimizing their properties for various innovative technologies. The study's findings have the potential to guide the chemical vapor deposition growth of hBN on metallic substrates and the synthesis of nanoporous or functionalized structures. Supported by the UK’s HPC Materials Chemistry Consortium and the Austrian Science Fund, this research marks a significant step towards harnessing the full potential of Hexagonal Boron Nitride for a sustainable and technologically advanced future.
