Abstract

original image

It's elemental! β-Rhombohedral boron was investigated as an elemental photocatalyst. Boron crystals were found to be photocatalytically active in the generation of .OH radicals under irradiation with visible light (see picture); however, the presence of an amorphous oxide layer on the surface of the crystals impaired their photocatalytic activity.
