Improvement in electrochemical performance of NiZrO3/rGO composite for energy-related applications

The advancement of effective electrocatalysts is crucial for the environmental friendly generation of oxygen by electrochemical water splitting. Current research focuses on manufacture of energy storage and conversion devices utilizing various mixed metal oxides with conductive two-dimensional surfaces. The renewable energy and sustainable energy sectors are affordable electrocatalysts with improved stability and electrocatalytic activity. This study investigates the synthesis of a novel NiZrO₃/rGO composite to create effective electrodes energy storage and conversion devices. The use of non-noble metal catalysts instead of noble metal catalysts is becoming more widespread due to their positive qualities such as environmental sustainability, cost-effectiveness and electrocatalytic performance. The capacitance of NiZrO₃/rGO composite was 2215 F/g at 1 A/g demonstrating stability after 10,000^th cycles over 50 h. The synthesized NiZrO₃/rGO composite exhibited Tafel slope of 41 mV/dec and overpotentials (η) of 256 mV calculated from CV analysis. The incorporation of graphene oxide into NiZrO₃ enhances the interfacial area and accelerates charge transport, leading to improved electrochemical performance. The material's exceptional stability indicated its viability for energy-storing and conversion devices.
