Hexagonal boron nitride (h-BN) powder, as a unique two-dimensional material, has demonstrated a wide range of applications in recent years in scientific research due to its excellent physicochemical properties. Its high thermal stability, chemical inertness, high insulating properties, and excellent mechanical properties make h-BN powder a popular choice for research teams to explore new materials and technologies.
Recently, an international collaborative research led by Hao-Min Wang's group at the Shanghai Institute for Microsystems has made an important breakthrough. They found that h-BN crystals are able to form micron-sized bubbles of controllable size on their surfaces when treated in hydrogen plasma. This phenomenon is attributed to the unique AA' stacking method between h-BN layers, which provides penetration channels for hydrogen atoms. In the plasma state, hydrogen decomposes into hydrogen atoms, and these hydrogen atoms are able to penetrate the multilayer structure of h-BN non-destructively and complex into hydrogen molecules between the layers. Due to the two-dimensional structural properties of h-BN, the hydrogen is effectively confined between the layers, resulting in the formation of gas bubbles. This discovery not only reveals the great potential of h-BN as a highly efficient hydrogen separation membrane, but also provides a new solution for the purification and utilization of clean energy, foreshadowing that h-BN will play an even more important role in future technological development.
The application areas of h-BN powders are wide and varied.
In high temperature environments, h-BN powders are able to withstand temperatures up to 2800°C without decomposing due to their extremely high thermal stability, making them ideal materials for the study of material behaviors, chemical reactions, and physical processes in high temperature environments.
In the field of electronics and optoelectronics, the high insulating properties and high thermal conductivity of h-BN powders make them the preferred choice for heat dissipation fillers and substrate materials for optoelectronic devices.
In the field of chemistry and catalysis, the chemical inertness and high stability of h-BN powders make them ideal for use as catalyst carriers or reaction media.
In addition, h-BN powders also show a wide range of applications in the field of nanotechnology and composite materials, often used as raw materials for the preparation of nanocomposites, providing strong support for the development of new materials.
In the field of energy and environmental science, h-BN powders also show great potential for application. Its high thermal conductivity and chemical stability make it an ideal raw material for the preparation of highly efficient thermal management materials and hydrogen storage materials.
At the same time, h-BN powder is also used in the preparation of electrode materials or diaphragm materials for solar cells, lithium-ion batteries and other energy devices, which makes an important contribution to the development of renewable energy.
In addition, h-BN powder also shows unique application value in dealing with environmental problems such as wastewater and exhaust gas, providing new solutions for environmental protection.
