Application

  • Multifunctional potassium hexafluorophosphate passivate interface defects for high efficiency perovskite solar cells: Potassium hexafluorophosphate (KPF6) is used to enhance the interface between SnO2 quantum dots and perovskite (Z Wang et al., 2021).
  • Potassium hexafluorophosphate additive enables stable lithium–sulfur batteries: An optimized amount of KPF6 added to the electrolyte improves the cycling stability of lithium-sulfur batteries (J Li et al., 2020).
  • Dual electrolyte additives of potassium hexafluorophosphate and tris (trimethylsilyl) phosphite for anode-free lithium metal batteries: KPF6 and tris(trimethylsilyl) phosphite enhance the electrochemical performance of anode-free lithium metal batteries (TM Hagos et al., 2019).

Ruthenium(II) complexes containing the tetradentate ligand bis[4(4'-methyl-2,2'-bipyridyl)]-1,n-alkane ("bbn "; n=10 and 12) have been synthesised and their geometric isomers separated. All [Ru(phen)(bbn )](2+) (phen=1,10-phenanthroline) complexes exhibited excellent activity against Gram-positive bacteria, but only the cis-α-[Ru(phen)(bb12 )](2+) species showed good activity

A series of pyridine- and lutidine-linked bis-N-heterocyclic carbene (NHC) palladium pincer complexes were electrochemically characterized and screened for CO2 reduction capability with 2,2,2-trifluoroethanol, acetic acid, or 2,2,2-trifluoroacetic acid (TFA) as proton sources. The lutidine-linked pincer complexes electrocatalytically reduce CO2 to
