MXene-related materials possess promising characteristics as electrical electrodes used for energy storage and conversion purposes, recognition for their diverse attributes, such as a substantial surface area, excellent metallic conductivity, and rapid redox process. However, the excessive combination and oxidation of surfaces have greatly restricted their application in many types of businesses. This work proved the production of WO3 nanosphere-interrelated MXene/GQDs (WO3/MXene@GQDs) nanocomposite by facial hydrothermal method. Electrochemical supercapacitors and water-splitting activities were implemented using these nanocomposites. The WO3/MXene@GQDs nanocomposite electrodes exhibited a superb specific capacity of 2851 C/g through 2.0 A/g. Moreover, the asymmetric devices based on nanocomposites achieved a notable specific energy of 81.3 Wh/kg and a power density (Pd) of 1750 W/kg, showcasing important cycling stability. The WO3/MXene@GQDs nanocomposite electrocatalyst demonstrated a low overpotential of 131.41 mV and a small Tafel slope value of 57.67 mV dec−1 for the HER. The fabrication hybrid electrodes retained 80.79% of their capacity and maintained 89.34% coulombic efficiency after 12,000 cycles. This research employs experimental studies to explore the application of WO3/MXene@GQD-based electrodes for the HER. The challenges associated with WO3/Ti3C2@GQD electrodes and their potential are also addressed. Our findings show future advancements in different and efficient electrocatalysts based on MXenes for hydrogen production via water-splitting technology.
