Surface Functionalization of Nanodiamond

A wet-chemical hydrogenation is hard to achieve. Most of all the separation of the catalyst (e.g., palladium on activated carbon) is very complicated. A reaction with zinc and hydrochloric acid in the sense of a Clemmensen reduction has not been described for nanodiamond either. 

The surface bromination occurs as a radical process with elemental bromine that is reacted with the nanodiamond as solution in chloroform. By the action of light, bromine radicals are generated to attack on the surface. For the reduced reactivity of bromine radicals, however, just a partial bromination is achieved, and the degree of surface covering remains comparatively low at 0.87 mmol g.
