| Abstract Scope |
Reduced graphene oxide (rGO) holds great promise for energy storage, sensors, and electronics due to its excellent conductivity and mechanical strength. However, existing reduction methods face challenges in cost and scalability. In this work, we demonstrate a scalable, low-cost plasma spraying technique for synthesising highly ordered rGO, achieving a high production rate of 52 g/h at just 4.36 USD/g. The resulting rGO exhibits a high C/O ratio (11.4), large surface area (198 m˛/g), superior conductivity (3288 S/m), thermal stability up to 600 °C, and low defect density (ID/IG = 0.18). These properties enable excellent electrochemical performance, with a specific capacitance of 275 F/g (96% retention after 10,000 cycles) for supercapacitors and a charge capacity of 182 mAh/g for sodium-ion batteries. This study positions plasma spraying as an efficient, industrially viable route for producing high-performance rGO for next-generation energy technologies. |
