Allgemeine Beschreibung

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.

Anwendung

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.

Cellulose fibers were engineered by in situ oxidative polymerization of aniline using ammonium persulfate as oxidant/initiator. The polyaniline/cellulose fiber composite was used for the treatment of Cr(VI)-contaminated water, and its effect was evaluated. Under the conditions studied, the composite exhibited

Chaperonins are ubiquitous molecular chaperones with the subunit molecular mass of 60kDa. They exist as double-ring oligomers with central cavities. An ATP-dependent conformational change of the cavity induces the folding of an unfolded protein that is captured in the cavity.
