Synopsis

In this paper we describe the large-scale synthesis of inorganic fullerene-like hexagonal boron nitride with vessel, hollow sphere, peanut, and onion structures by reacting BBr3 with the synergic nitrogen sources NaNH2 and NH4Cl at 400−450 °C for 6−12 h. Here, the IF-like BN peanut structure is reported for the first time. The similarity in the structure between h-BN and graphite is responsible for the formation of IF-like BN with nanostructures of vessels, hollow spheres, peanuts, and onions. Section:

Abstract

In this paper we describe the large-scale synthesis of inorganic fullerene-like (IF-like) hexagonal boron nitride with vessel, hollow sphere, peanut, and onion structures by reacting BBr3 with the synergic nitrogen sources NaNH2 and NH4Cl at 400−450 °C for 6−12 h. The composition of products could be confirmed to be pure boron nitride with hexagonal structures by the XRD patterns and FT-IR, XPS, and EDXA spectra. The representative HRTEM images clearly reveal the layerlike features of the products. Here, the peanut-like structure of the IF-like BN is reported for the first time, and added to the list as one kind of new morphology of BN nanomaterials. The similarity in the structure between -BN and graphite is responsible for the formation of IF-like BN with nanostructures of vessels, hollow spheres, peanuts, and onions.

  Multi- and double-walled boron nitride nanotubes (BNNTs) have been synthesized with the aid of a floating nickel catalyst via the catalytic chemical vapor deposition (CCVD) of either the amine-borane borazine (B3N3H6) or the polyhedral-borane decaborane (...

A Template-free Route to Sb2S3 Crystals with Hollow Olivary Architectures

Qiaofeng Han, Juan Lu, Xujie Yang, Lude Lu and Xin Wang

Olivary Sb2S3 microcrystallines have been first synthesized via a hydrothermal process at 180 °C for 24 h using hydrochloric acid, SbCl3, and Na2S as starting materials. The powder X-ray diffraction (XRD) pattern shows the product corresponds to the pure ...
