NOVELTY - Preparing electrified bismuth trisulfide nanorod RGO composite structure comprises (i) taking soluble bismuth salt, and dissolving in homologous acid solution to obtain colorless transparent solution, (ii) taking graphene oxide dispersing in deionized water, and adding colourless transparent solution to obtain black mixed solution, (iii) adding thioacetamide, allowing to stand to obtain black flocculent precipitate, and washing, (iv) dispersing the product in hydrazine hydrate solution, and stirring to obtain black precipitate, (v) purifying black precipitate, washing, and vacuum drying. USE - The method is useful for preparing electrified bismuth trisulfide nanorod RGO composite structure (claimed). ADVANTAGE - The composite structure has good electrochemical performance. DETAILED DESCRIPTION - Preparing electrified bismuth trisulfide nanorod RGO composite structure comprises (i) taking 2 mmol soluble bismuth salt, and dissolving in 50 ml homologous acid solution to obtain colorless transparent solution, (ii) taking 5-10 mg graphene oxide ultrasonically dispersing in 50 ml deionized water, and adding colourless transparent solution obtained in the step (i), obtain black mixed solution, (iii) taking black mixed solution obtained in the step (ii), adding 5 mmol thioacetamide, allowing to stand for 24-48 hours to obtain black flocculent precipitate, taking out black flocculent precipitate, and washing using deionized water to a pH value of 7, (iv) taking the product obtained in the step (iii), dispersing in 50% hydrazine hydrate solution, and continuously stirring for 8-12 hours using magnetic force stirrer to obtain black precipitate, (v) taking the black precipitate obtained in the step (iv), purifying by centrifugation, first washing for 3 times with ethanol, then washing for 3 times using deionized water, and carrying out vacuum drying at 70 degrees C for 4-6 hours to obtain electrified bismuth trisulfide nanorod RGO composite structure.
