Abstract
This study investigates the potential of Cr2O3/Sn-MOF (PANI) composites for next-generation energy storage systems. The unique combination of Cr2O3and Sn-MOF (PANI) enhances hydrophobicity, charge transport, and surface redox activity, making it an attractive material for energy storage. However, challenges such as the reassembly of individual components can reduce electrochemical efficiency. To overcome this, we integrated Cr2O3and Sn-MOF (PANI), filling gaps between layers and enhancing electroactive sites. Through this innovative composite synthesis, we improved ion/electron transport pathways and prevented material restacking. The Cr2O3/Sn-MOF (PANI) electrodes exhibited specific capacities of 794 C/g in a three-electrode assembly. The Cr2O3/Sn-MOF (PANI)//AC device achieved 68.9 Wh/kg energy density at 970 W/kg power density. The composite Cr2O3/Sn-MOF (PANI) provide an overpotential of 73.7 mV and tafel slope of 55.7 mV/dec in HER applications. This study highlights the potential of Cr2O3/Sn-MOF (PANI) electrode for future energy storage and electrocatalytic applications.Graphical abstract(a) Represents the CV and (b) represents the GCD study for Cr2O3/Sn-MOF(PANI) composite
