Mesoporous BN was prepared at 550 {sup o}C for 10 h or so via a simple reaction between NaBH{sub 4} and CO(NH{sub 2}){sub 2}. X-ray diffraction demonstrates the formation of t-BN with lattice constants a=2.46 and c=6.67 A. High-resolution transmission electron microscopy displays a lot of porous films in the product, which possesses a high surface area of 219 m{sup 2} g{sup -1} and a pore size primarily around 3.8 nm tested by nitrogen adsorption-desorption method. The mesoporous BN exhibits a strong luminescence emission around 3.41 eV in the cathodoluminescence spectra, a high stability in both morphology and structure, and good oxidation resistance up to 800 {sup o}C. The byproducts generated during the reaction are responsible for the formation of the mesoporous BN. -- Graphical abstract: The mesoporous BN with a high specific surface area of 219 m{sup 2} g{sup -1} exhibits a strong luminescence emission around 3.41 eV in the CL spectra, high thermal stability in both morphology and structure, and good oxidation resistance up to 800 {sup o}C.
