چکیده

Biodiesel is a sustainable alternative to fossil fuels, playing a crucial role in reducing greenhouse gas emissions and environmental impact. The development of efficient catalytic processes, particularly utilizing nanocatalysts, is of significant importance for enhancing biodiesel production. This study presents the synthesis and characterization of ZnO nanoparticles supported on multi-walled carbon nanotubes (MWCNTs). The physical and chemical properties of the synthesized nanocatalysts were analyzed through XRD, and SEM techniques, confirming successful deposition of ZnO on MWCNTs. The catalytic activity was evaluated for biodiesel production from soybean oil under different methanol-to-oil ratios and reaction times. Results demonstrated a maximum conversion efficiency of 99% at a methanol/oil ratio of 55:1 and a reaction time of 45 minutes. Reusability tests indicated that the catalyst maintained high performance over seven cycles with only slight activity loss. The proposed method offers notable advantages, including higher yields, cost-effectiveness, and environmental sustainability. Overall, this nanocatalyst system holds promise for industrial applications, contributing to more efficient and eco-friendly biodiesel manufacturing processes.
