Allgemeine Beschreibung

Manganese(II) chloride is an inorganic salt soluble in water. It exists in several hydrated forms, including the anhydrous, dihydrate (MnCl2.2H2O), and tetrahydrate (MnCl24H2O) states. It is used in the production of dry cell batteries and as a precursor for other manganese compounds. Additionally, manganese(II) chloride is also employed in the synthesis of organomanganese compounds and used as a catalyst in various organic reactions.

Anwendung

Manganese(II) chloride can be used as:      
  • A precursor in the preparation of manganese oxide coated natural spherical graphite materials, which are used for improving the electrochemical performance of the graphite materials, making them suitable for applications in batteries and supercapacitors.     
  • A key component in the preparation of polyvinyl alcohol/manganese chloride composite films, which are find potential applications in areas such as sensors, energy storage devices, and flexible electronics due to their improved optical, mechanical, and thermal properties.      
  • A precursor in the synthesis of Mn-doped CsPbCl3 perovskite nanocrystals for enhancing their optical properties and quantum yield, which are vital for their application in improving the efficiency of solar cells.  
  • A catalyst for the transfer dehydrogenation of glycerol to lactic acid.

Developing highly efficient electrocatalysts based on cheap and earth-abundant metals for CO2 reduction is of great importance. Here we demonstrate that the electrocatalytic activity of manganese-based heterogeneous catalyst can be significantly improved through halogen and nitrogen dual-coordination to modulate the

Lithium-ion batteries' characteristics make them popular for electricity storage due to portability, rechargeability, and low cost.

The prevailing strategies for heat and electric-power production that rely on fossil and fission fuels are having a negative impact on the environment and on our living conditions.

Fragen

  1. How can a glass ampule-like vial be opened without a score mark?

    1 Antwort
    1. Using a diamond glass cutter like item 933392 or a sharp-edged triangle metal file is recommended to score the vial all around in order to break it open.
