A simple and straightforward method using microwave-assisted reactions is presented for the functionalization of graphene oxide with aromatic non-aromatic amines.
Carbon-based nanomaterials, such as polymeric graphitic carbon nitrides, have garnered attention due to their metal-free structure, exceptional thermal stability and unique extended aromatic system, imparting them with semiconductor properties.
Abstract Preparation of tin(II) sulfide, semiconductor material, has been accomplished by thermal decomposition easily prepared organotin dithiocarbamate complexes: [Sn{S 2 CNEt } Ph ] (1), }Ph 3 (2), Ph] (3) and CN(C 4 H 8 )} Bu (4). Phase‐pure sulfide obtained pyrolysis these precursors at 350 °C in N . Thermogravimetric analysis, X‐ray powder diffraction, scanning electron microscopy, probe microanalysis 119 Sn Mössbauer spectroscopy revealed that the complexes decompose a single sharp...
Abstract Organotinsulfides Sn 4 S R 6 (R = methyl, n ‐butyl and phenyl) were employed as single‐source precursors for nanometric tin sulfides. The residues obtained after pyrolysis in hydrogen, nitrogen oxygen characterized by X‐ray diffraction, 119 Mössbauer spectroscopy, scanning electron microscopy probe microanalysis. results clearly showed the formation of tetragonal SnO 2 (rutile‐type structure) pure phase orthorhombic γ‐Sn 3 when Bu (2) was precursor. spectroscopic very important...
Porous carbon materials were prepared at low temperatures via thermal decomposition of iron, nickel and cobalt N,N-diethyldithiocarbamates (DDT).X-ray diffraction data showed two peaks 2θ (25.5° 43.5°) that indicate the presence graphite-like structures.Raman spectra displayed D G bands in range from 1312 to 1321 cm -1 1587 1593 , respectively, which fitted with 4 components.All intensity D* (1190 ) D'' (1500 bands, assigned sp 2 -sp 3 bonds disordered carbonaceous amorphous carbon,...
