摘要

Response surface methodology (RSM) is crucial in optimizing complex processes like reducing sugar production, offering a systematic approach to parameters, and analyzing the intricate interactions between multiple factors to maximize sugar yield. The current study focuses on enhancing sugar production from corn stover biomass using the nanotechnology-based pretreatment. Corn stover was pretreated with photocatalytic aluminum-doped zinc oxide (Al-ZnO) nanoparticles under ultraviolet irradiation. This was followed by dilute acid (H2SO4) and basic (NaOH) hydrolysis to measure the formation of sugars (glucose, arabinose, galactose, mannose, and xylose). A Box-Behnken design within RSM was used to optimize operating parameters such as ultraviolet irradiation time, Al-ZnO nanoparticles concentration, and H2SO4 and NaOH concentrations. The results showed that longer UV irradiation exposure had an inverse effect on sugar production, while nanoparticle concentration had a direct and positive effect on sugar production. In photocatalytic acid hydrolysis, the sugars yield reached up to 19.02 g/L at 75 UV time, 1 g/L Al-ZnO nanoparticles, and H2SO4 concentration of 2mmnM. For basic hydrolysis, a higher sugar yield of 15.76 (g/L) was achieved at 75 UV time, 1 g/L Al-ZnO nanoparticles, and NaOH concentration of 1.25 M.
