Herein, we report a novel CuPPc (copper polymeric phthalocyanine)/CF (copper foam) nanoflake material, as precatalyst for the generation of an excellent water oxidation catalyst (WOC). Under optimized conditions, the CuPPc-derived Cu oxide affords a current density of 10 mA cm-2 under an overpotential (η) of 287 mV and sustains for at least 50 h in 1.0 M KOH. The strategy presented here is favorable to develop the electrocatalysts for water splitting.

有机聚合物CuPPc衍生的氧化铜作为水氧化的高效电催化剂。

在本文中，我们报道了一种新型的CuPPc（铜聚合物酞菁）/ CF（铜泡沫）纳米片材料，作为产生优良水氧化催化剂（WOC）的预催化剂。在最佳条件下，源自CuPPc的Cu氧化物在287 mV的过电势（η）下提供10 mA cm-2的电流密度，并在1.0 M KOH中维持至少50 h。此处提出的策略有利于开发用于水分解的电催化剂。
