Researchers from the Dalian Institute of Chemical Physics and the University of Chinese Academy of Sciences have developed a photocatalyst for the selective decarboxylation of fatty acids to produce diesel- and jet-range molecules under mild conditions (30 °C, H 2 pressure ≤0.2 MPa). A photocatalytic decarboxylation strategy for the production of alkanes from bio-derived fatty acids. The photocatalytic decarboxylation procedure is highlighted, and the interactions between photogenerated carriers (holes and electrons) and fatty acids are schematically shown in the photoredox cycle. Huang et al. Industrial low-value fatty acid mixtures—e.g., soybean and tall oil fatty acids)—can be transformed into alkane products in high yields (up to 95%). A paper on their work appears in Nature Catalysis . Long-chain alkanes are among the most important chemicals in modern society as they are the major components in diesel and jet fuel and can be used as feedstocks for olefin and aromatic production.
