A Hierarchical Phosphorus Nanobarbed Nanowire Hybrid: Its Structure and Electrochemical Properties.

Nanostructured phosphorus-carbon composites are promising materials for Li-ion and Na-ion battery anodes. A hierarchical phosphorus hybrid, SiC@graphene@P, has been synthesized by the chemical vapor deposition of phosphorus on the surfaces of barbed nanowires, where the barbs are vertically grown graphene nanosheets and the cores are SiC nanowires. A temperature-gradient vaporization-condensation method has been used to remove the unhybridized phosphorus particles formed by homogeneous nucleation.

Assembly of Ring-Shaped Phosphorus within Carbon Nanotube Nanoreactors.

A phosphorus allotrope that has not been observed so far, ring-shaped phosphorus consisting of alternate P and P structural units, has been assembled inside multi-walled carbon nanotube nanoreactors with inner diameters of 5-8 nm by a chemical vapor transport and reaction of red phosphorus at 500 °C. The ring-shaped nanostructures with surrounding graphene walls are stable under ambient conditions. The nanostructures were characterized by high-resolution transmission electron microscopy, scanning transmission electron microscopy, energy-dispersive X-ray spectroscopy, Raman scattering, attenuated total reflectance Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy.

Nanocarved MoS-MoO Hybrids Fabricated Using in Situ Grown MoS as Nanomasks.

The morphology and hybridization of nanostructures are crucial to achieve properties for various applications. An in situ grown three-dimensional (3D) MoS nanomask has been adopted to control the morphology and hybridization of molybdenum compounds. The in situ generated MoS mask on MoO nanobelt surfaces allowed us to fabricate a 3D c-MoO@MoS hybrid nanostructure, in which c-MoO is a carved MoO nanobelt with a well-distributed hole pattern.
