(238h) Mechanistic Insights into the Catalytic Innovations in Biomass Valorization

Catalysts are fundamental to enhancing biomass valorization processes, enabling selective and efficient conversion of lignocellulosic feedstocks into high-value bio-based chemicals and fuels. This study explores key catalytic strategies through experimental and theoretical investigations. The CO2-assisted synthesis of PdNi nanoalloys demonstrates highly selective hydrogenation of 5-Hydroxymethylfurfural, promoting sustainable bio-refining. Plasma-enabled catalysis facilitates the targeted synthesis of bio-based phenolics from lignin-derived feedstocks. The catalytic fast pyrolysis of levoglucosan, furfural, and furan over HZSM-5 is analyzed using both experimental and theoretical approaches to reveal optimal reaction pathways. Additionally, the role of bimetallic catalysts and Brønsted acid-supported metal sites in anisole hydrodeoxygenation is elucidated using density functional theory (DFT), offering a deeper understanding of deoxygenation mechanisms. By integrating catalytic advancements with mechanistic insights, this study provides a comprehensive framework for optimizing biomass conversion technologies, advancing sustainable biofuel and biochemical production within a circular bioeconomy.
