Ted Oyama, Effects of ball-milling treatment on physicochemical properties and solid base activity of hexagonal boron nitrides, Catalysis Science and Technology, 10.1039/c8cy00940f, 9, 2, 302-309, 2019.01, Hexagonal boron nitride (h-BN) was ball-milled at various rotation speeds (150–600 rpm) using a planetary ball-mill. Ball-milling disrupted the layered structure of the h-BN, resulting in significant increases of surface area. Ball-milling at 400 rpm gave the highest surface area of 412 m2 g−1 while higher rotation speeds decreased the surface areas due to agglomeration. Moreover, ball-milling resulted in the emergence of amino- and hydroxyl groups on the surface which were observed by Fourier transform infrared spectroscopy,
and partial oxidation of the surface boron by the formation of B–OH groups was confirmed by X-ray photoelectron spectroscopy. The appearance of trigonal B–O and tetrahedral B–O was observed by boron-11 magic-angle spinning nuclear magnetic resonance spectroscopy. The number of base sites was increased with the increase of rotation speeds of milling, corresponding to the formation of amino groups. The ball-milled h-BN showed catalytic activity for the nitroaldol reaction between nitromethane and benzaldehyde
in which the h-BN milled at 400 rpm exhibited the highest reaction rate and turnover frequency. In addition, the ball-milled h-BN could convert glucose with the formation of fructose at 40 °C whereas pristine h-BN showed no activity. The base sites were mainly responsible for the catalytic activity..

Ted Oyama , Hexagonal Boron Nitride as a Solid Acid-Base Catalyst , The 8th Tokyo Conference on Advanced Catalytic Science and Technology , 2018.08, This study investigated the use of hexagonal boron nitride (h-BN) as a novel catalyst with base and acid functionalities. For use as a solid catalyst, the layered structure of h-BN was disrupted by ball-milling, exposing boron and nitrogen edge sites as well as increasing the surface area. FTIR, XPS and 1H MAS NMR indicated that amino- and hydroxyl groups were formed adjacently on the surface of h-BN by ball milling. The ball-milled h-BN was found to function as a solid acid–base catalyst. The coexistence of acid and base sites enhanced its activity for the nitroaldol reaction..

Ted Oyama, Ball-milled Boron Nitride as a Novel Solid Acid-Base Catalyst, 2018 International Symposium on Advancement and Prospect of Catalysis Science & Technology, 2018.07, This study reveals that amino and hydroxyl groups were formed simultaneously at adjacent positions on the h-BN surface by the simple ball-milling, and these groups functioned as active cooperative acid-base sites for the nitroaldol reaction..
