1. A process for synthesis of barium bismuth sulfide nanofibers, said process comprising the following steps;
a. dissolving barium nitrate, bismuth nitrate pentahydrate and thiourea in a solvent system to obtain a dispersion containing complex of barium bismuth sulfide; and b. mixing at least one surfactant in the dispersion under continuous agitation to obtain a mixture; c. heating the mixture at a temperature ranging between 120° C. and 180° C. in an apparatus for 24 hours followed by cooling at a temperature ranging between 20° C. and 30° C. to obtain a precipitate; and d. washing the precipitate by employing at least one solvent selected from the group consisting of water, ethanol, methanol, isopropanol and acetone to obtain nanofibers of barium bismuth sulfide. |
