Popis: Highly active cobalt tin sulfides (CTS) nanocomposite have been prepared in a short time at 70 °C by using microwave-assisted process and solvothermal synthesis process. According to improve the activity, cobalt tin acetate hydroxide prepared using microwave treatment is used for the preparation of CTS in both synthetic methods. The resultant product has been characterized using X-ray diffraction, transmission electron microscope (TEM), Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and photoelectrochemical analysis. The Microwave processed cobalt tin sulfides (MW-CTS) nanocomposite offers less size of 180 nm while comparing with solvothermal based CTS (ST-CTS). Also, possess a high surface area of 464.54 m2g-1 without much aggregation due to the uniform heating and more reaction time. Moreover, the CTS synthesized by microwave method offers higher catalytic activity than obtained from the solvothermal process, owing to smaller size, high surface area, enhanced charge transfer rate with high optical absorption plays a vital role in governing the photoelectrochemical properties.
