General description
Sodium borohydride (NaBH4) is the most commonly available borohydride used in several industrial applications. It is considered as a selective reducing agent due to its ability to selectively reduce aldehydes and ketones into their corresponding alcohols in the presence of other functional groups such as nitro, ester, amide, lactone, epoxide, and nitriles. Ethanol and methanol are usually employed as solvents in NaBH4 reduction reactions.
Application
Sodium borohydride (fine granular) can be used as a reducing agent to prepare:
- Zero valent iron nanoparticles supported on mesoporous carbon (Starbon) by in situ reductions of Fe3+ ions.
- Ag nanoparticles on graphene using AgNO3 as a precursor.
- Ag-Pd/ZrO2 catalytic system applicable in plasmonic catalysis. It can also be used as a source to store as well as generate hydrogen for energy-carrier applications.
