由同一导电基材上的氧化和还原反应耦合产生的所谓局部电池代表了众所周知的金属腐蚀原因。在本研究中，我们试图证明基于局部电池反应原理的催化系统可以使用金属掺杂的共价三嗪骨架作为催化单元成功制造。开发了一种携带铂和铜掺杂共价三嗪骨架分别作为氧化和还原过程催化剂的导电基底，以制造同时将硝酸盐还原为一氧化二氮和氧化氢气的局部电池催化单元。
So-called local cells resulting from the coupling of oxidation and reduction reactions on the same conductive substrate represent a well-known cause of metallic corrosion. In the present study, we attempted to demonstrate that catalytic systems based on the principle of local cell reactions can be successfully fabricated using metal-doped covalent triazine frameworks as catalytic units. A conductive substrate carrying platinum- and copper-doped covalent triazine frameworks as catalysts for the oxidation and reduction processes, respectively, was developed to fabricate a local cell catalytic unit for the concurrent reduction of nitrate to nitrous oxide and oxidation of hydrogen.
