Abstract

High-quality SiO_x nanoflowers have been generated by heating mixed SiC/Co powder films in a CO atmosphere. The structural features associated with different stages of the growth were monitored by SEM, TEM, EDX, and XRD analysis. A plausible mechanism for the formation of exquisite flowerlike structures is proposed in which SiC reacts with CO, the Co particles acting as a catalytic template, to yield amorphous SiO_x branches. Numerous loops and branches were also observed which may arise either as a result of bifurcation or coalescence. Use of Co₂O₃ instead of Co as catalyst leads to abnormal flowers exhibiting secondary growth.
