3.1. Structural and Morphological Characterization In this study, pristine NTO was synthesized via a hydrothermal method followed by calcination, and OVs were subsequently introduced through a solid-state, solvent-free grinding process using NaBH 4 as the reducing agent at 300 °C aging for 1h. (20) To easily recognize the synthetic conditions by the samples notation, the prefix R of NTO means that the NaBH 4 reduction step was applied to prepare this sample.

In this work, carbon dots were synthesized from sodium polyacrylate and demonstrated as versatile, effective electrode/electrolyte additives for enhancing specific capacitance and cycling stability of supercapacitors. An addition of only 5 wt % carbon dots to the TiO2 electrode significantly improved the specific capacitance by 348%. Furthermore, the addition of carbon dots to the Na2SO4 electrolyte additionally enhanced the specific capacitance by 229%.
