Abstract
ABSTRACTThe transition to biofuels as viable alternatives to fossil fuels is increasingly critical, given the rising demand for sustainable energy. However, biofuel production is hindered by challenges such as feedstock scarcity, elevated production costs, and environmental impacts. Nanotechnology has the potential to significantly improve the efficiency and durability of biofuel production processes, thereby overcoming these challenges. Although there has been significant research on using nanomaterials in biofuel production, there needs to be more emphasis on understanding and addressing the difficulties of integrating these materials and developing strategies to overcome them. This review systematically examines the role of nanotechnology in various biofuel production pathways, including biodiesel, biogas, bioethanol, biohydrogen, hydrotreated vegetable oils, and Fischer–Tropsch synthesis. We discuss how nanomaterials improve key aspects of biofuel production, such as catalysis, microbial conversion, biomass pretreatment, and separation. Despite these advancements, nanotechnology has challenges, including nanoparticle toxicity, increased operational costs, and technical limitations. We propose potential solutions to these issues, emphasizing the need for interdisciplinary collaboration and innovative approaches. By effectively integrating nanotechnology into biofuel production, the energy sector can move toward a more sustainable and environmentally friendly future.
