Abstract The excessive use of fossil fuels has significantly increased environmental stress, driving the need for green, sustainable biofuel alternatives. Innovations in photocatalysis (PC), electrocatalysis (EC), and their synergistic approaches, like photothermal catalysis (PTC), photo‐enzymatic (PENC), photoelectrocatalysis (PEC), offer advanced methods biomass conversion into biofuels, surpassing traditional limitations. However, comprehensive research on these processes is still lacking. This review aims to systematically analyze recent progress catalytic strategies biomass‐to‐biofuel conversion. It first describes characteristics, types, properties biofuels.

Merging efficient H2 generation with high-value utilization of biomass via a solar-driven catalytic redox technology presents promising strategy for overall biorefinery. As the most abundant aromatic polymer in nature, lignin is considered an ideal sacrificial agent to enhance reductive evolution, coproducing chemicals/fuels instead waste carbon oxides. However, development energy-efficient and productive photocatalysis system remains challenging. Herein, photothermal cocatalytic was developed synergistic enhancement on activities. A feasible synthesis method proposed precisely construct light-sensitive heterojunction between active Pt NixP, bridged by technical lignin–carbon. Benefiting from advanced modulation effect lignin–carbon, accelerated electron transfer structural rearrangement were realized defective catalyst surface. Combining optimized band gap structure, evolution efficiency boosted under cocatalysis showed splendid rate 10.7 mmol·gcat–1·h–1 based lignin-derived monomer (vanillyl alcohol), 15-fold higher than either or thermocatalysis alone. The obtained (2.9 mmol·gcat–1·h–1) surpassed existing level biomass. Meanwhile, controllable coupling its derived monomers enhanced simultaneously, yielding C13–C16 dimers (43.8% yield) Cα node, which act as precursors jet fuel. This work advances upgrading hydrogen energy biofuels.

Abstract Solar‐driven photocatalysis is a promising strategy for clean hydrogen (H 2 ) generation cooperated with selective organic synthesis. Lignin, rich in aromatic units and functional groups, serves as an ideal hole sacrificial agent substrate, facilitating H evolution yielding high‐value chemicals/fuels. To boost overall photocatalytic redox efficiency, thermal catalysis was further combined to enhance the transfer activity of photo‐generated carriers. And highly controllable Cu‐based catalyst developed using technical lignin‐carbon electron buffer. The active‐pyrolyzed layer precisely regulated crystal dispersion Cu species on Cu/SiO , simultaneously dynamically constructing active electron‐rich 0 electron‐deficient σ + (1 < ≤ 2) sites. Excellent thermo‐photo performances were achieved, rate up 1313.2 μmol·g cat −1 ·h yield 45.2% C13–C16 dimers from lignin monomers. This study reveals utilization catalysts, well efficient production jet fuel precursors.
