Effect of KOH on the Energy Storage Performance of Molasses-Based Phosphorus and Nitrogen Co-Doped Carbon

In this study, we have evaluated the effect of potassium hydroxide (KOH) on energy storage performance metal-free carbon-based materials prepared from molasses. Molasses are a renewable-resource biomass and economical by-product sugar refinement, used here as carbon precursor. Two co-doped using molasses were synthesized via time cost-efficient microwave carbonization process, with ammonium polyphosphate phosphorus nitrogen doping agent. The (PNDC) samples in presence absence chemical activating agent (KOH), to study role activation PNDCs. Physical characterizations performed gain insight into composition, pore size topographical data each material. Electrochemical characterization cyclic voltammetry 1 M sulfuric acid (H2SO4) well 6 KOH electrolytes, revealed high current density specific capacitance for chemically activated material (PNDC2) compared one without (PNDC1). value 244 F/g electrolyte was obtained PNDC2. It is concluded that addition prior increases surface functionality, which significantly enhances electrochemical properties PNDC such density, stability, capacitance.
