High efficiency was found for desulfurization and denitrogenation processes to treat diesel using either the hybrid material {[MoO₃(2,2′‐bipy)][MoO₃(H₂O)]}_n or the octanuclear complex [Mo₈O₂₂(OH)₄(di‐tBu‐bipy)₄] (2,2′‐bipy = 2,2′‐bipyridine, di‐tBu‐bipy = 4,4′‐di‐tert‐butyl‐2,2′‐bipyridine) as catalysts. These processes were employed in a single procedure to simultaneously remove sulfur (dibenzothiophene, 4‐methyldibenzothiophene, and 4,6‐dimethyldibenzothiophene) and nitrogen (indole and quinoline) compounds from diesel. A reaction time of two hours was sufficient to achieve at least 99.9 % S removal and 97 % N removal. Furthermore, the catalytic systems presented a high capacity to be reused/recycled for consecutive desulfurization/denitrogenation cycles.

Mo（VI）-联吡啶催化剂对柴油进行脱硫和脱氮工艺

发现使用杂化材料{[MoO ₃（2,2'-bipy）] [MoO ₃（H ₂ O）]} _n或八核配合物[Mo ₈ O ₂₂ ]进行脱硫和脱氮处理柴油的效率很高。（OH）₄（二-吨卜联吡啶）₄ ]（2,2'-联吡啶= 2,2'-联吡啶，二吨卜联吡啶= 4,4'-二-叔-2-丁基，2'-联吡啶）作为催化剂。这些过程仅需一个步骤即可从柴油中同时去除硫（二苯并噻吩，4-甲基二苯并噻吩和4,6-二甲基二苯并噻吩）和氮（吲哚和喹啉）化合物。两小时的反应时间足以实现至少99.9％的S去除和97％的N去除。此外，催化系统具有很高的可重复使用/再循环能力，可用于连续的脱硫/脱氮循环。
