Solution Structure of Alkaline NaBH4 Solution: A sight From X-ray Scattering

Abstract

Abstract. The time and space-averaged structure of alkaline aqueous NaBH 4 solution were given by X-ray scattering with a five-circle goniometer in Beijing Synchrotron radiation facility. Then the hydration structure of BH 4 -were presented through geometrical model calculation, the characteristic distance and the hydration number of BH 4 -(B-O(w)) in higher concentration solutions were determined to be 0.34 nm and 2~3. There are three kinds of ion associating structure of BH 4 -and Na + in higher concentration solutions.
