摘要

The formation of inexpensive and readily available electrocatalysts for hydrogen evolution reaction (HER) is advantageous for advancement of H2 development. Using hydrothermal route, we effectively enhanced the HER activity of SnS. This was accomplished through the creation of a nanohybrid made up of tin sulphide (SnS) and PANI nanostructure. The SnS/PANI nanohybrid demonstrates enhanced electrocatalytic performance for the HER when compared to the pure SnS material. The produced electrocatalysts (SnS and SnS/PANI) have undergone various physical analyses, like scanning electron microscopy (SEM), X-ray diffraction (XRD), and electrochemical investigation to evaluate their morphology, structure morphology and electrocatalytic activity for HER. The SnS/PANI nanohybrid offers multiple benefits for improving HER electroactivity, such as a larger accessible specific surface area (SSA), enhanced edge-terminated structures and superior conductivity. The electrocatalyst exhibits remarkable durability in basic medium and shows a low Tafel value (43 mV/dec) and (ɳ) overpotential (-171 mV) at -10 mA/cm2. The current findings indicate that SnS/PANI nanohybrids may serve as a promising option for materials related to energy production and conversion systems.
