Preparation of high purity BCN hollow spheres by pyrolyzing a simple polymeric precursor

A novel, simple and rapid route to the synthesis of boron cabonitride nanosheets: combustive gaseous unfolding

“…Therefore, the analysis substantiates the carbonitride, rather than nitride, nature of the material. The appearance of a small peak related to the oxygen seems to be due to the surface contamination (see EELS analysis) and is almost always observed in similar cases 4, 7, 17, 18 . The percentages of B, C, and N in the B x C y N z nanomaterial were calculated from survey scan spectrum to be approximately 39%, 12%, and 42%, respectively, implying the chemical formula of BC 0.3 N 1.08 .

“…Nanoscale BCN has been synthesized in various nanostructured forms such as nanowires 5 , nanofibers 6 , nanosheets 7 – 10 , nanotubes 11 – 17 , spherical nanocages 2 , hollow spheres 18 , mesoporous 19 , and amorphous 20 , 21 structures. To synthesize these various BCN nanostructures, several methods have been employed depending on the desired morphology of the product.…”

Growth and characterization of BCN nanotubes with high boron and nitrogen content

“…11,35 The sp2-bonded B=N and C=N bonds are known to emit photoelectrons that bonded to the core state of N at 398.0-398.3 eV and 399-400 eV, respectively. [33][34][35] The content of pyridine-like N in the sample at 850 • C is highest among the four samples. Similarly, the C1s spectrum in figure 3(c) has three peaks with a broad shoulder.…”

“…The chemical states of B, C, and N elements were investigated using X-ray photoelectron spectroscopy figure 3(b), the spectrum is mainly composed of two peaks through Gaussian fitting. The peak of N1s with binding energies of 398.2 eV can be assigned to the N atoms in pyridine-like N-C structures; [33][34][35] the peak of N1s with binding energies of 399.0 eV can be assigned to the N atoms bonded to C atoms as graphite-like structures. 11,35 The sp2-bonded B=N and C=N bonds are known to emit photoelectrons that bonded to the core state of N at 398.0-398.3 eV and 399-400 eV, respectively.…”
