以正硅酸四乙酯（TEOS）为硅源、十二胺（DDA）为模板剂、偏钒酸铵为金属活性组分，通过溶胶-凝胶法合成钒改性HMS（V-HMS）介孔材料，利用SEM、小角XRD、BET、FT-IR和TG-DTA对V-HMS进行表征。以30%的H₂O₂为氧化剂，催化2-萘酚氧化合成2-羟基-1，4-萘醌。分别探究了反应温度、反应时间、金属的负载量、催化剂的质量以及物料摩尔比对该反应的影响。结果表明，反应温度为50℃、反应时间为3 h、催化剂质量为0.04 g、催化剂金属负载量为4%、n（2-萘酚）∶n（H₂O₂）=1∶48时，2-羟基-1，4-萘醌的收率最高达到95.5%。催化剂可以重复使用。

Vanadium modified HMS (V-HMS) mesoporous materials are synthesized by sol-gel method using tetraethyl orthosilicate (TEOS) as silicon source, dodecylamine (DDA) as template and ammonium metasvanate as metal active component. The prepared V-HMS is characterized by scanning electron microscope (SEM), small angle XRD, N₂ adsorption desorption (BET), Fourier transform infrared (FT-IR) and thermal analysis (TG-DTA). 2-Hydroxy-1, 4-naphthoquinone is synthesized through oxidation of 2-naphthol by using 30% H₂O₂ as oxidant and V-HMS as catalyst. Influences of reaction temperature, reaction time, loading amount of metal, catalyst dosage and materials ratio on the reaction are investigated. The results indicate that the yield of 2-hydroxy-1, 4-naphthoquinone is the highest, reaching 95.5% when reaction temperature remains at 50℃, the reaction lasts for 3 h, catalyst dosage is 0.04 g, the loading amount of metal in the catalyst is 4%, and the molar ratio between 2-naphthol and H₂O₂ is 1∶48. The catalyst can be reused.
