Descripción general

Ammonium sulfate is a less corrosive sulfating agent that is used to synthesize the highly efficient acid catalyst for biodiesel production.

It can also be used to enhance the stability of perovskite solar cells. The incorporation of sulfate species minimizes chemical degradation at the perovskite/ETL interface. It is insoluble in acetone, alcohol and ether.

Aplicación

Ammonium sulfate can be used:
  • As a structure-directing agent (SDA) to prepare hexagonal WO3 nanorod thin films for high-performance energy storage devices. The addition of (NH4)2SO4 prevents agglomeration of crystals.
  • As an electrolyte for aqueous ammonium dual-ion batteries and MnO2/carbon supercapacitors.
  • As a blowing agent to prepare porous carbon structures for supercapacitors. These porous materials show high capacitance and long-term stability.
  • To enhance the stability of perovskite solar cells. The incorporation of sulfate species minimizes chemical degradation at the perovskite/ETL interface.
