Descrizione

Descrizione generale

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.

Applicazioni

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.
