📄 Abstract（原文）
Nanomaterial-based photocatalysts represent a cutting-edge approach for advancing sustainable bioenergy generation, facilitating solar-driven biomass conversion, hydrogen production, CO2 reduction, and bio-oil upgrading under mild and environmentally friendly conditions. This chapter presents an extensive overview of prominent nanomaterials including TiO2, ZnO, CdS, g-C3N4, perovskites, MOFs, and hybrid composites, emphasizing their high surface areas, tunable bandgaps, and strong redox properties. Evidence from recent research shows that photocatalytic pretreatment can significantly accelerate lignin breakdown, lower crystallinity, and boost sugar release by as much as 260%, thereby achieving notable increases in hydrogen yields (up to 47%) and methane yields (up to 158%). In combined hydrolysis–fermentation processes, nano-photocatalysts reduce microbial lag phases and enhance hydrogen output by more than 100% by promoting superior charge transfer and increasing enzymatic activity. For CO2 photoreduction, engineered heterojunctions enable the targeted synthesis of value-added compounds such as formic acid at rates exceeding 430 μmol g⁻1 h⁻1, while biomass-derived catalysts for hydrogen generation achieve production rates of up to 14.67 mmol g⁻1 h⁻1 under solar irradiation. In the context of bio-oil upgrading, atomically dispersed single-atom catalysts attain greater than 98% selectivity for key monomers, and nanostructured zeolites along with metal–organic hybrids boost aromatic yields and deoxygenation efficiencies to over 90%. Despite these advances, challenges remain in catalyst stability, recovery, cost-effective synthesis, and scale-up. Addressing these through interdisciplinary innovations in materials science, reactor engineering, and environmental safety will be essential for realizing large-scale, light-assisted biorefineries that align with global carbon neutrality goals.
