BiOBr-BN Photocatalysts for Promoting Photocatalytic NO Oxidation and Inhibiting Toxic By-products

Photocatalysis has been regarded as an emerging and promising air purification technology. However, nitrogen dioxide (NO 2 ) as the by-product is easily generated in the process of photocatalytic NO oxidation, which is more toxic and harmful to human health than NO. To inhibit the generation of NO 2 and promote the deep oxidation of No into nitrate (NO 3 -), boron nitride (BN) nanosheets was used as templates and bismuth oxybromide (BiOBr) nanosheets were introduced by the in-situ growth method to fabricate the two dimensional-two dimensional (2D-2D)
