Synthesis of mesoporous BN and BCN exhibiting large surface areas via templating methods

The synthesis of mesoporous boron nitride (MBN) and mesoporous carbon nitride (MBCN) with a very high surface area and pore volume, was analyzed. The samples were prepared by crushing the as-synthesized flakes in an agate mortar, mixing them with ethanol, sonication, and spreading the resultant mixture on a carbon film supported on a Cu grid. MBCN ands MBCN materials possess relatively high surface areas of 740 and 650 m²/g and large pore volumes of 0.69 and 0.60 cm³/g. The results show that these materials could be used as catalytic supports operating at high temperature in anoxidative atmosphere.
