Control of structure-enriched abundant unsaturated or dangling bonds can precisely and effectively tune the activity and durability of materials. In this study, a new strategy to obtain fusiform nanoarchitectures (FNAs) has been found for the first time using Te nanostructures as the model materials. TeFNA could be transformed from Te nanorods (NRs) with different diameter (50, 25 nm), even the ultrathin nanowires (NWs) (10 nm). Besides, a novel perspective into the preliminary mechanism combining collision theory with density functional theory simulations was proposed to explain the transformation progress. In the mixing system of hexadecyl trimethylammonium bromide (CTAB) solution, the Te NR/NWs keep the translational motion together with the centroid rotation. The velocity of the two ends of TeNR/NWs is higher than that in the center under the reaction condition based on collision theory; meanwhile, the summation energy of both O2 and CTAB put on Te (0001) surface is −606.992 eV, which means that the T...
