Stay away! Graphitic carbon nitride (g-C₃N₄)-coated alumina (CN-Al) is investigated as a support material for a cobalt-based Fischer–Tropsch synthesis (FTS) catalyst. The g-C₃N₄ blocks the interaction between Co and alumina to hinder the formation of irreducible cobalt oxide species, and improves the dispersion of metallic Co species on the CN-Al support. Because of the improved dispersion and reducibility of the Co species on the CN-Al support, the catalytic FTS activity of Co/CN-Al is higher compared with the conventional Co/Al₂O₃ catalyst.

费托合成中石墨在氮化碳涂层氧化铝载体上的自动还原行为

远离！研究了石墨化氮化碳（gC ₃ N ₄）包覆的氧化铝（CN-Al）作为钴基费-托合成（FTS）催化剂的载体材料。gC ₃ N ₄阻止了Co与氧化铝之间的相互作用，从而阻碍了不可还原的氧化钴物质的形成，并改善了金属Co物质在CN-Al载体上的分散性。由于改善了Co物种在CN-Al载体上的分散性和可还原性，因此与常规Co / Al ₂ O ₃催化剂相比，Co / CN-Al的催化FTS活性更高。
