Onions are a girl's best friend : While catalyzing the oxidative dehydrogenation of n ‐butane, ultradispersed nanodiamonds (UDD) are transformed into onionlike carbon (OLC, see picture). This surface‐activated bulk transformation from sp 3 ‐ to sp 2 ‐hybridized carbon atoms is concomitant with an enhanced product selectivity to the desired butenes. In addition, the synthesis of OLC is achieved at temperatures 600 K lower than reported so far.
