Pressure-controlled fabrication of stibnite nanorods by the solvothermal decomposition of a simple single-source precursor

A simple single-source precursor to stibnite (Sb2S3) synthesized from SbCl3 and thiourea in methanol was characterized. The thermal decomposition of the precursor in polar solvents resulted in the formation of one-dimensional Sb2S3 nanocrystallites with the growth direction along the c axis. It is found that the as-prepared Sb2S3 nanorods are formed through the spontaneous connection of adjacent particles. The pressure in the solvothermal process plays an important role in the formation of the nanorods.
