It remains challenging to efficiently remove oxygen from bio-oil (O% = 10-30 wt%) to produce fuels with much lower oxygen content (&lt; 2 wt%). Catalytic hydrodeoxygenation (HDO) is an effective and widely adopted strategy for O removal from bio-oil. In this presentation, our recent work on the development and fundamental understanding of earth-abundant Fe-based catalysts for improved selectivity and catalyst stability in HDO of lignin-derived phenolics will be discussed, including: 1) stabilization and promotion of Fe by trace amount of PGMs (e.g., Pd); 2) stabilization of Fe and tailoring of reaction pathways involved in HDO by functionalized C and alkali metals; and 3) mechanistic insight on hydrogen activation and spillover as well as their influence on HDO involved in catalytic pyrolysis.
