摘要

The progress of an actual, economical and maintainable material for energy storage applications is essential in today's technological era. The developed nanohybrid sample, SrBiO3/rGO, was designed to enhance storage energy capabilities and catalytic performance. In the current work, a hydrothermal method was used to prepare a SrBiO3/rGO nanohybrid. Electrochemical properties were conducted to compare the behaviour of SrBiO3 and SrBiO3/rGO electrodes to assess their capacitive properties for supercapacitor characteristics. The SrBiO3/rGO nanohybrid displayed remarkable hybrid characteristics, delivering a specific capacitance (898.48 F/g) at 1 A/g and reserved 78.67% specific capacitance after the 5000th cycle. Moreover, the SrBiO3/rGO displayed exceptional and durable electrocatalytic activity, requiring reduced 226 mV overpotential (η) and 44 mV/dec Tafel gradient at 10 mA/cm in the oxygen evolution reaction (OER) procedure. These outcomes indicate that SrBiO3-based graphene nanohybrid holds promising potential for energy-saving devices and effective catalytic characteristics.
