The utility model provides a non-pure water solution electrolysis device, and relates to the technical field of electrolytic hydrogen production. The device comprises an anode, a cathode, an ion exchange membrane and permeable membrane layers, the ion exchange membrane is arranged between the anode and the cathode, and the permeable membrane layers are arranged on the side, away from the ion exchange membrane, of the anode and the side, away from the ion exchange membrane, of a cathode catalyst layer. Electrolyte chambers are arranged between the anodes and the corresponding adjacent permeable membrane layers and between the cathodes and the corresponding adjacent permeable membrane layers, and a non-pure water solution chamber is arranged on one side, far away from the ion exchange membrane, of each permeable membrane layer. By additionally arranging the permeable membrane layer and utilizing the concentration difference between the electrolyte and the non-pure water solution, water molecules can spontaneously pass through the permeable membrane layer while other macromolecules, impurities and the like cannot pass through the permeable membrane layer, pure water is continuously supplemented for the electrolyte, and the purpose of directly electrolyzing the non-pure water solution is achieved; the method can be realized without any external power, and the cost is low.

This invention relates to a method for the electrocatalytic oxidation of anisole to anisole sulfoxide using iron-based complexes, belonging to the fields of homogeneous catalysts and electrocatalytic oxidation technology. The invention utilizes an iron-based complex formed by coordination between a tetraamide macrocyclic ligand (TAML-H4) and metallic iron as a homogeneous molecular catalyst, with water as the sole oxygen source, to construct an electrocatalytic anisole oxidation system. Through the synergistic effect of the catalyst and water, a proton-coupled electron transfer and single-electron oxidation process occurs at the anolyte, resulting in the loss of two electrons and two protons to generate a high-valence iron-oxygen active intermediate [Fe]. Ⅴ (O)(TAML)] – This invention achieves highly efficient and selective oxidation of anisole, generating the high-value-added product benzyl sulfoxide at the anode. It eliminates the need for additional strong oxidants, employs mild reaction conditions, boasts high atom economy, and is environmentally friendly, making it suitable for the green conversion of sulfides in the synthesis of fine chemicals. This provides a feasible pathway for the industrial production of sulfoxide compounds.
