AB - Efficient energy conversion technologies require cost-effective and durable catalysts for water oxidation. This study presents SnS2/C composite synthesized via solvothermal method to enhance electrocatalytic performance in water splitting. Morphological analysis reveals that carbon incorporation disrupts the flower-like SnS2 nanosheets, increasing active site accessibility and improving charge transfer efficiency. Three different electrolytes (KOH, PBS and H2SO4) are systematically employed to evaluate the material’s electrocatalytic activity comprehensively. The electrochemical tests indicate that pure SnS₂ exhibits an overpotential (η) of 410 mV at 10 mA/cm2 for oxygen evolution reaction (OER) in 1 M KOH. Integration of carbon significantly lowers this value to 180 mV with a tafel slope of 103 mV/dec for SSC12 (1:2 SnS₂/C) composite. For hydrogen evolution reaction (HER) in acidic media, SSC12 achieves an η of 275 mV at 500 mA/cm2 with a tafel slope of 121 mV/dec. The catalyst further demonstrates strong durability for OER in 1 M KOH but shows diminished HER activity in 0.5 M H2SO4. This study demonstrates the synergistic role of carbon in enhancing SnS₂ catalytic attributes, emphasizing the potential of these composites for sustainable energy conversion applications.
