Photocatalytic activity of Pb₂Ti₂O_5.4F_1.2 for water oxidation was dependent strongly on the loaded metal cocatalyst species as well as their preparation conditions. Among the cocatalysts examined, the highest activity was obtained with RuCl₃-impregnated Pb₂Ti₂O_5.4F_1.2 heated under a flow of H₂ at 523 K. Z-scheme overall water splitting using the optimized Ru/Pb₂Ti₂O_5.4F_1.2 was also accomplished.

用金属氧化物助催化剂修饰可见光响应型 Pb2Ti2O5.4F1.2 以改善光催化 O2 分解，实现 Z 型总体水分解

Pb ₂ Ti ₂ O _5.4 F _1.2对水氧化的光催化活性强烈依赖于负载的金属助催化剂种类及其制备条件。在所检测的助催化剂中，RuCl ₃浸渍的 Pb ₂ Ti ₂ O _5.4 F _1.2在 H ₂流下于 523 K 下加热获得了最高的活性。使用优化的 Ru/Pb ₂ Ti ₂ O 的 Z 型整体水分解_5.4 F _1.2也完成了。
