| Summary, etc. | The study aimed to synthesize and characterize sawdust-based nanocellulose incorporated with TiO₂ (SNC/TiO2) and evaluate its photocatalytic performance on the degradation of methyl orange. Nanocellulose was extracted by ultrasonication and acid hydrolysis methods. The acid hydrolysis process parameters: sulfuric acid concentration (45wt%- 75wt%), time (60 min- 130 min), and temperature (60°C – 120 °C) were optimized using box-behnken design with SNC % recovery as the output response. The best ultrasonication time was 45 mins, and optimum acid hydrolysis parameters were, 67.39 wt% of acid concentration, 108 min contact time, and 108 °C hydrolysis temperature resulting in maximum recovery of nanocellulose of 70.98%. The Analysis of variance (ANOVA) was carried out to identify the most significant factors that influence the percentage of nanocellulose recovery. The maximum recovery was validated using the predicted response of the generated RSM model. The SNC/TiO2 was synthesized using additional method using different mass ratio (2:0.5, 2:1, and 2:1.5). The photocatalytic activity of SNC/TiO2 nanocomposite was found to be effective in degrading methyl orange dye, with the optimal mass ratio of SNC/TiO2 determined to be 2:1.5. Furthermore, the Scanning Electron Microscopy (SEM) result implied that the incorporation of SNC/TiO2 was successful. |
