摘要
以钼酸钠(Na2MoO 4·2H 2O)为钼源,硫脲(CS(NH 2)2)为硫源,考察了钼硫摩尔比、反应温度、反应时间、添加剂四丁基溴化铵(TBAB)4个因素对MoS 2微球制备的影响。结果表明,当钼硫摩尔比为1:4、反应温度220℃、反应时间18 h和TBAB用量0.6 g时成功合成了大小较均匀、表面由大量薄片构成的MoS 2微球。此时,对应的MoS 2对电极光电转换效率达到传统Pt对电极的86.6%,具有成为新型非Pt对电极的潜力。
With Na 2MoO 4·2H 2O as molybdenum source and CS(NH 2)2 as sulfur source,the effects of molar ratio of molybdenum to sulfur,reaction temperature,reaction time and additive tetrabutyl ammonium bromide(TBAB)on the preparation of MoS2 microspheres were investigated.The results showed that MoS2 microspheres were successfully synthesized with molybdenum sulfur molar ratio of 1:4,reaction temperature of 220℃,reaction time of 18 h and TBAB dosage of 0.6 g.At this time,the photoelectric conversion efficiency of the corresponding MoS2 counter electrodes reaches 86.6%of the traditional Pt counter electrodes,which has the potential to become a new type of non-Pt counter electrodes.
