애플리케이션

Potassium borohydride (KBH4) can be used as a reducing agent for the synthesis of:       
  • Copper nanoparticles by the reduction of copper salts.
  •  Enantioselective allylic alcohols by the catalytic reduction of enones and ketones in the presence of chiral N,N′-dioxidescandium(III) complex catalyst.,·        
  • Azoxybenzenes by the reduction of nitroarenes in the presence of phase transfer catalyst PEG-400.

It can also be employed as a boron source in the nickel–boron alloy, which is electrodeposited on carbon fiber to improve catalytic graphitization of carbon.
