Abstract

The time and space-averaged structure of alkaline aqueous NaBH4 solution were given by X-ray scattering with a five-circle goniometer in Beijing Synchrotron radiation facility. Then the hydration structure of BH4- were presented through geometrical model calculation, the characteristic distance and the hydration number of BH4-(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 BH4- and Na+ in higher concentration solutions. The [(H2O)4Na(H2O)2Na(H2O)4]2+(with Na-Na distance of 0.363 nm) , the [(H2O)4Na(BH4)2Na(H2O)4]0 (with Na-Na distance of 0.421 nm), and the [BH4Na(H2O)4]0 with the Na-B distance of 0.30 nm
