一般描述

在还原氧化石墨烯(RGO)对电极中加入水合肼可以改善其在染料敏化太阳能电池(DSSC)中的性能。

应用

关于水合肼对牙釉质样品的脱蛋白作用已有研究。它可作为以下过程的还原剂：
  • 制备银纳米颗粒。
  • 取代单硝基苯衍生物向相应苯胺的转化。
  • 与石墨一起用于硝基化合物(芳香族和脂肪族)到氨基化合物的转化。
水合肼可用于制备:
  • 通过与5-苄基-2-苯基色氨酸反应得到3-(2-苄基-6-羟基苯基)-5-苯基吡唑。
  • 通过与1,3-二苯基-2-丙烯-1- 1反应得到3,5-二苯基-2-吡唑啉衍生物。
  • 与3-芳基酰基-3,4-二氢喹啉-2(1H)-喹喔啉酮-反应生成3′- 1,2,3,4,4′,5′[喹诺沙林-2,5′ -吡唑]-喹喔啉酮-。
  • 它还可用于硝基芳香族胺的催化还原。
