Abstract

original image

NiO nanoparticles on pristine carbon nanotubes, with high crystallinity and uniform dispersion, are synthesized using atomic layer deposition (ALD) by Y. Qin, X. Guo, M. Knez, and co-workers. The sizes of the NiO nanoparticles can be precisely controlled by varying the number of ALD cycles. The as-prepared NiO/CNT hybrid nanostructures, described on page 3390, exhibit a greatly enhanced electrochemical catalytic ability and stability for methanol electro-oxidation. This method provides a general route to prepare functional and complex hierarchical nanostructures with precise control over the size of the supported nanoparticles.
