General description

Triethanolamine borate(TEAB) is a water-solubleecofriendly catalyst that can be prepared by the reaction of boric acid andtriethanolamine in aqueous solution. It possesses a Lewis pair (boron as Lewis acid, tertiary amine as Lewis base). It is widely used in the field of catalysis, corrosion inhibition,lithium-ion secondary batteries, and flame-retardant polymers.
It can be formed from the 1:1 aqueous solution of boric acid and triethanolamine.

Application

Triethanolamine borate can be used:
  • As a surface stabilizing electrolyte additive for Ni-rich layered oxide cathode. TEAB inhibits Ni dissolution in the Ni-rich cathode and suppresses the electrolyte decomposition.
  • To prepare highly crystalline wide band gap perovskite solar cells with enhanced efficiency. TEBA helps to slow down the rapid crystallization and facilitates the formation of uniform perovskite films with reduced defects.
  • As a bifunctional catalyst for the cycloaddition of CO2 with epoxides.
  • As a precursor to synthesize boron-containing epoxy resin with flameretardant properties.
