Description

General description

Potassium tetraborate tetrahydrate(K₂B₄O₇· 4H₂O) is a white crystalline salt with good buffering properties. It is widely used in the field of electrochemical water splitting, disinfectant, and the oil and gas industry.

Application

Potassium tetraborate tetrahydrate can be used:

• As an electrolyte for electrochemical water splitting reaction. The addition of K₂B₄O₇ · 4H₂O enhances the oxygen evolution activity of the catalyst.
• To synthesize carbon foams with hierarchical pores, for supercapacitors. K₂B₄O₇ · 4H₂O helps to tune the pore structure of carbon foams.
• To prepare green formulation for the removal of pyrite(FeS₂) scales from oil and gas tubings.
