A Novel Sonochemical Method for the Preparation of Nanophasic Sulfides: Synthesis of HgS and PbS Nanoparticles

The present perspective presents a novel platform for the synthesis of catalyst free photoluminescent carbon nanoparticles derived from the combustion of camphor in a single step flame process. The soot particles were investigated using Fourier transformation infrared spectroscopy, thermogravimetry, Raman, transmission emission microscopy, X-ray diffraction, UV and photoluminescent spectroscopy. The soot particles exhibited a diamond-like carbon nanostructure, with the presence of hydrophobic functional groups imparting superhydrophobic characteristics. The camphor soot particles revealed the presence of highly graphitized amorphous carbon, which was confirmed by the appearance of G, D1 D2, D3 and D4 bands in the Raman spectra. Photoluminescence of the soot particles was observed when soot particles were excited at λmax. A red shift was clearly noted in the UV spectrum of the soot in different solvents. The agglomeration of camphor soot particles was discussed by measuring the fractal dimensions (Df) of the particles. Combustion of soot particles occurs at 450 °C, approx. 100 °C lower than that of graphene. In-depth investigations suggest the use of these photoluminescent camphor soot particles for superhydrophobic coating applications.

Electrodeposition of lead sulphide in acidic medium

Semiconducting carbon films from a natural source: camphor

Synthesis of conducting fibers, nanotubes, and thin films of carbon from commercial kerosene

Carbon electrodes prepared from the pyrolysis of camphor at 1000°C in argon atmosphere have been found to facilitate Li-ion intercalation similar to that observed with carbons generally prepared at temperatures well above 2000°C. An irreversible intercalation capacity of these carbon/lithium half cells during the initial discharge was measured to be 0.34, after which fully reversible Li-ion intercalation takes place right from the 1st to the 20th charge-discharge cycle, with a constant intercalation capacity of 0.61. Camphor-pyrolyzed carbon thus appears as a promising candidate for investigation as a lithium battery electrode material.
