This study investigates the utilization of Graphitic Carbon Nitride (g-C3N4) as a photocatalytic material for enhancing biofuel production from rice straw, an agricultural residue with potential for sustainable energy generation. The melaminesynthesized g-C3N4 is used as a pretreatment agent, where rice straw is immersed in a g-C3N4 solution and exposed to 450-600 nm solar irradiation for varying durations. This pretreatment process modifies the biomass structure, resulting in a reduction of the silica content to 72.05% and an increase in the carbon percentage to 41.58% within the rice straw. Methane production demonstrates the effectiveness of g-C3N4-based pretreatment, with methane production from raw rice straw at 231 mL/gVS. Co-digestion with waste activated sludge increases methane production to 507 mL/gVS, while a 3 h pretreatment further enhances it to 547.16 mL/gVS, and a 6 h pretreatment leads to 595.5 mL/gVS. Comprehensive characterization techniques confirm the successful modification of biomass structure using g-C3N4. |
