文摘

This paper presents the synthesis of water-dissolvable Na₂SO₄ nanowires and nanorods by a simple chemical reaction between CuSO₄ and NaBH₄ in ethylene glycol. By adjusting the pH and the monomer concentration, the aspect ratio and size of the Na₂SO₄ nanowires could be tuned. Na₂SO₄ nanorods, nanowhiskers, nanowires, and submicrorods were obtained. Optimal chemical potential is believed to be the dominant driving force for the growth of Na₂SO₄ nanowires during the synthesis. We also demonstrated the Na₂SO₄ nanotubes obtained by the electron beam radiolysis of Na₂SO₄ nanowires. The mechanism of selective radiolysis is also investigated.
