我们报告了一种通过水溶液中铁腐蚀的水分解模式，称为“水离子分裂（AiS）”。在本文中，我们通过控制铁和水之间的反应来研究这一现象。采用油漆的伪牺牲保护方法来选择控制铁腐蚀的阳极和阴极形成位置。然后，通过使用 BTB 溶液（其颜色与 pH 值相对应）来可视化 AiS 反应，以产生与水离子分布相对应的颜色图案。很明显，通过腐蚀控制处理可以将水选择性地分离成质子和氢氧根离子。在这种情况下，利用伴随铁腐蚀的BTB溶液的颜色图案来估计质子的扩散系数，然后通过求解扩散方程来计算机模拟水离子分布。
We report a water decomposition mode called ‘Aquaionic Splitting (AiS)’ by means of iron corrosion in aqueous solution. In this paper, we investigated the phenomenon by controlling the reaction between iron and water. A pseudo-sacrificial protection method with oil paint was employed to select the anode and cathode formation locations that govern iron corrosion. Then, the AiS reaction was visualized by using BTB solution, whose colour corresponds to pH, to produce colour patterning that corresponds to the aquaion distribution. It has become clear that water can be selectively separated into protons and hydroxide ions by corrosion control treatment. In this vein, the diffusion coefficient of protons was estimated by using the colour patterning of BTB solution that accompanies iron corrosion, and aquaion distribution was then computer simulated by solving the diffusion equation.
