Representative work: Abstract Conversion of syngas (CO, H 2 ) to hydrocarbons, commonly known as the Fischer–Tropsch (FT) synthesis, represents a fundamental pillar in today's chemical industry and is typically carried out under technically demanding conditions (1–3 MPa, 300–400 °C). Photocatalysis using sunlight offers an alternative and potentially more sustainable approach for the transformation of small molecules (H 2 O, CO, CO 2 , N 2 , etc.) to high‐valuable products, including hydrocarbons. Herein, a novel series of Fe‐based heterostructured photocatalysts (Fe‐ x ) is successfully fabricated via H 2 reduction of ZnFeAl‐layered double hydroxide (LDH) nanosheets at temperatures ( x ) in the range 300–650 °C Abstract Ni‐based catalysts are traditionally considered unsuitable for the Fischer–Tropsch syntheses of olefins, due to the very strong hydrogenation ability of metallic Ni. Herein, this paradigm is challenged. A series of MnO supports nickel catalysts (denoted herein as Ni‐ x ) are fabricated by H 2 reduction of a nickel‐manganese mixed metal oxide at temperatures ( x ) ranging from 250 to 600 °C. The Ni‐500 catalyst displays unprecedented performance for photothermal CO hydrogenation to olefins, with an olefin selectivity of 33.0% under ultraviolet–visible irradiation.
