The results and prospects of the in situ (in the cell volume) and ex situ (outside the cell) use of aqueous solutions of hydrogen peroxide electrogenerated from oxygen in gas-diffusion electrodes (GDE) of carbon black are discussed. It is shown that using GDE based on technological A-437E carbon (acetylene black) and mesostructured carbon CMK-3 allows the Н₂О₂ solution with the concentration higher than 3 M to be obtained. It is found that electrosynthesized hydrogen peroxide may be used in situ with the high efficiency both in the indirect electrosynthesis of important organic and inorganic target products and in the destruction of organic and inorganic pollutants present in waste waters of different origin. Under the ex situ conditions, it is possible to synthesize the more concentrated solutions of Н₂О₂, organic peroxoacids, and inorganic peroxosolvates and also to carry out mineralization of exometabolites in autonomous life-support systems. These results may be helpful in selecting the most appropriate versions of using hydrogen peroxide solutions electrogenerated from oxygen for solving particular problems.

氧气电生产生的过氧化氢水溶液原位和异位使用的前景

摘要

讨论了在炭黑的气体扩散电极（GDE）中原位（在电池体积中）和非原位（在电池外部）使用由氧气电生成的过氧化氢水溶液的结果和前景。结果表明，使用GDE基于技术A-437E碳（乙炔黑）和介观结构碳CMK-3允许Н ₂ О ₂获得浓度高于3 M的溶液。已经发现，电合成的过氧化氢可以在重要的有机和无机目标产物的间接电合成以及在不同来源的废水中存在的有机和无机污染物的破坏中被高效地原位使用。下易地条件，可以合成Н的更浓缩的溶液₂ О ₂，有机过氧酸盐，和无机peroxosolvates并且还开展自主生命支持系统exometabolites的矿化。这些结果可能有助于选择最合适的版本，使用由氧气产生的过氧化氢溶液来解决特定问题。
