含钴多氧钛酸酯 (TiCo) 是简单且可规模化制备 Nocera 型 CoOx 水氧化电催化剂的优异前体。 TiCo笼作为氟化物掺杂氧化锡电极上二氧化钛基质中钴离子的储存库,并在pH中性水中的磷酸盐缓冲液中原位形成用于析出O-2的活性CoOx催化剂,具有高稳定性。
Cobalt-containing polyoxotitanates (TiCo) are excellent precursors for the simple and scalable preparation of Nocera-type CoOx water-oxidation electrocatalysts. The TiCo cages serve as a reservoir for cobalt ions in a titania matrix on fluoride-doped tin oxide electrodes, and form, in situ, the active CoOx catalyst for O-2 evolution with high stability in phosphate buffer in pH neutral water.
