The Lindqvist anion [Mo₆O₁₉]²⁻ was in situ intercalated into layered double hydroxides (LDHs) via a one-pot hydrothermal method. The heterogeneous catalyst was applied in ultra-deep desulfurization of fuels under mild conditions, and exhibited high activity for dibenzothiophene (DBT), benzothiophene (BT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT). The above sulfur-containing compounds could be completely transformed into their corresponding sulfones under the stoichiometric O/S molar ratio (O/S molar ratio = 2). Furthermore, the catalyst could be easily recovered and reused at least 7 times without an obvious decrease in performance. The possible desulfurization mechanism was also studied in detail.

一锅法合成聚氧钼酸根阴离子插入层状双氢氧化物及其在温和条件下在燃料的超深度脱硫中的应用†

所述林克韦斯特阴离子[沫₆ ø ₁₉ ] ^2-是原位嵌入到层状双氢氧化物（水滑石）通过一釜水热法。该非均相催化剂在温和条件下用于燃料的超深度脱硫，并且对二苯并噻吩（DBT），苯并噻吩（BT）和4,6-二甲基二苯并噻吩（4,6-DMDBT）表现出高活性。在化学计量的O / S摩尔比（O / S摩尔比＝ 2）下，上述含硫化合物可以完全转化为它们相应的砜。此外，该催化剂可以容易地回收和重复使用至少7次，而性能没有明显降低。还详细研究了可能的脱硫机理。
