Powering up the energy storage: Exploring the potential of Graphitic Carbon Nitride-Strontium Oxide Nanohybrid for next-generation energy and photocatalytic applications

The world today is facing an unprecedented environmental and energy crisis. To tackle these issues, there is a growing focus on developing advanced energy storage and photocatalytic systems. In this study, we explored the potential of novel graphitic carbon nitride-strontium oxide nanohybrids (GCN-SrO NH) for next-generation supercapacitor and photocatalytic applications. The green microwave-assisted approach was applied to syn-thesize desired materials. The GCN-SrO NH electrode exhibited an excellent specific capacitance of 482 F/g at 0.5 A/g with an energy density of 16.7 Wh/kg and a power density of 146.2 W/kg. A two-electrode symmetric supercapacitor was assembled to further examine the capacitive performance of GCN-SrO NH in practical ap-plications. Consequently, the GCN-SrO NH//GCN-SrO NH symmetric supercapacitor device displayed an exceptional specific capacitance of 242 F/g at 0.5 A/g. The device delivered the highest energy density at 18.9 Wh/kg with an outstanding power density of 187.5 W/kg. The practicability of the assembled device was also demonstrated by glowing red LED. Moreover, GCN-SrO NH based catalyst showed excellent degradation effi-ciencies (97.21 %, 98.59 %, and 92.9 %) against methylene blue (MB), methyl orange (MO), and rhodamine B (RhB) dyes under visible light. This research reveals the potential of GCN-SrO NH for cutting-edge energy storage and environmental applications.
