Application

Tin(II) fluoride (SnF2) can be used:
  • As an inhibitor of Sn4+ in fabrication of formamidinium tin iodide (FASnI3) perovskite solar cells (PSCs) via SnF2–pyrazine complex formation.
  • As a catalyst in glycerol ketalization, Knoevenagel condensation and aldol-type reactions.
  • In the synthesis of α, β-epoxy ketone from α, α-dibromoacetophenone and aliphatic and aromatic aldehyde via oxidative addition of carbon-halogen bonds.
  • In the stereocontrolled [3 + 3] , [3 + 4], [3 + 5] annulations reactions.

State-of-the-art halide perovskite solar cells have bandgaps larger than 1.45 eV, which restricts their potential for realizing the Shockley-Queisser limit. Previous search for low-bandgap (1.2 to 1.4 eV) halide perovskites has resulted in several candidates, but all are hybrid organic-inorganic compositions, raising potential concern regarding

Noble metal nanoparticles have attracted considerable attention due to their useful capabilities as heterogeneous catalysts. However, they are usually prepared using various organic stabilizing agents that negatively affect their catalytic activities. Herein, we report a facile, clean, and effective method
