Abstract

The front cover picture represents a meta–air battery composed of a metal anode and a graphite cathode modified with pyridine penta-coordinated Fe phthalocyanine, which is an extremely active catalyst for the oxygen reduction reaction when the NaOH supporting electrolyte is used. When in the presence of other electrolytes, the activity of the catalyst decreases as the Fe active sites are poisoned by the interaction with the anions. Therefore, batteries with lower power density are obtained if in the presence of Cl⁻>Br⁻>HSO₄⁻> ClO₄⁻>NO₃⁻>OH⁻. More information can be found in the Research Article by Federico Tasca and co-workers (DOI: 10.1002/celc.202400186).

封面：五配位铁酞菁在各种酸性溶液中发生氧还原反应的电化学评价（ChemElectroChem 16/2024）

封面图片展示的是由金属阳极和石墨阴极组成的元空气电池，石墨阴极由吡啶五配位铁酞菁改性而成，当使用 NaOH 支持电解质时，铁酞菁是氧还原反应中极为活跃的催化剂。当存在其他电解质时，由于铁的活性位点与阴离子相互作用而中毒，催化剂的活性就会降低。因此，如果存在 Cl->Br->HSO4->ClO4->NO3->OH-，电池的功率密度就会降低。更多信息，请参阅 Federico Tasca 及其合作者的研究文章（DOI: 10.1002/celc.202400186）。
