General description

The addition of hydrazine hydrate to reduced graphene oxide (RGO) counter electrode improves its performance in dye-sensitized solar cells (DSSC).

Application

Hydrazine hydrate has been used for the deproteination of the enamel samples in a study. It may be used as a reducing agent in the following:
  • Preparation of silver nanoparticles.
  • Transformation of monosubstituted nitrobenzene derivatives to the corresponding anilines.
  • Along with graphite for the conversion of nitro compounds (aromatic and aliphatic) to the amino compounds.
Hydrazine hydrate may be used to prepare:
  • 3-(2-Benzyloxy-6-hydroxyphenyl)-5-styrylpyrazoles by reacting with 5-benzyloxy-2-styrylchromones.
  • 3,5-Diphenyl-2-pyrazoline derivatives by reacting with 1,3-diphenyl-2-propen-1-one.
  • 3′-Aryl-1,2,3,4,4′,5′-hexahydrospiro[quinoxalin-2,5′-pyrazol]-3-ones by reacting with 3-arylacylidene-3,4-dihydroquinoxalin-2(1H)-ones.
  • It may also be used in the catalytic reduction of nitroarenes to aromatic amines.
