Abstract

The synthesis of nano-fibrillar boehmite through electrolysis with a sacrificial aluminum anode in the presence of 0.1 mol/L sulfate electrolyte solutions at initial pH 9 and at 60°C has been investigated. The beneficial use of ammonium salt has been justified to maintain pH at a level compatible for the exclusive formation of boehmite during electrolysis from aluminate solutions. According to the experimental results and analyses inferred from XRD, TEM and EDS characterizations, the underlying mechanism has been described.
