Abstract In this investigation, we present an efficient electrochemical methodology to prepare nano-particulate TiO2 having a nano-crystalline composition of 40% Anatase and 60% Brookite, without need for subsequent thermal treatments (which are typically applied to alter the amount of amorphicity). This procedure for oxide synthesis is novel as it involves the galvanostatic dissolution of remelted Titanium Components, thus constituting a promising technological route for re-using Titanium-containing metallic pieces from the secondary metals industry to produce nanocrystalline TiO2 powders as a high value-added primary product. The experimental results presented showed that the faradaic efficiency of the TiO2 electro-synthesis, crystalline purity, and dispersion of the electro-generated TiO2 material was significant, despite the fact that the titanium content of the remelted titanium components was less than 80%.

通过电化学溶解重熔钛组分制备含有锐钛矿和布氏石纳米晶相的纳米颗粒 TiO 2

摘要 在这项研究中，我们提出了一种有效的电化学方法来制备纳米颗粒 TiO2，其纳米晶组成为 40% 锐钛矿和 60% Brookite，无需后续热处理（通常用于改变非晶性量） . 这种氧化物合成方法是新颖的，因为它涉及重熔钛成分的恒电流溶解，从而构成了一条有前途的技术路线，用于再利用二次金属工业中的含钛金属片来生产纳米晶 TiO2 粉末作为高附加值的初级产品。实验结果表明，电合成 TiO2 的法拉第效率、晶体纯度和电生 TiO2 材料的分散性是显着的，
