High-quality two-dimensional (2D) nanosheets of B 4 C were synthesized using a facile combustion reaction with a reaction mixture comprising boron oxide (B 2 O 3 ), magnesium (Mg), and polyvinylchloride (C 2 H 3 Cl) n . The ability to tune the nanosheets of boron carbide was achieved by controlling the combustion temperature within a range of 1500–1700 °C and by using polyvinylchloride powder as the carbon source. FE-SEM and TEM images of the acid leached combustion products show sheet-like B 4 C particles with thicknesses of about 10–50 nm and edge lengths from 0.1 to several micrometers. The chemistry of the combustion process and the formation mechanism of B 4 C nanosheets are discussed based on the experimental findings. [ABSTRACT FROM AUTHOR]
