The CuO@CuFeO core-shell structure represents a new family of photocatalysts that can be used as photoelectrodes that are able to produce hydrogen under a broad spectrum of visible light. Herein, we report a novel approach for the production of this active film by the thermal conversion of CuFe Prussian Blue Analogues. The outstanding photoelectrochemical properties of the photocathodes of CuO@CuFeO were studied with the use of combinatory photo-electrochemical instrumental techniques which proved that the electrodes were stable over the whole water photolysis run under relatively positive potentials. Their outstanding performance was explained by the coupling of two charge transfer mechanisms occurring in core-shell architectures.
CuO@CuFeO核壳结构代表了一类新型光催化剂，可作为光电极，在宽光谱可见光下能够产生氢气。在此，我们报道了一种通过热转化铜铁普鲁士蓝类似物来制备这种活性薄膜的新方法。利用组合光电化学仪器技术研究了CuO@CuFeO光阴极优异的光电化学性质，结果表明，在相对正的电位下，整个水光解过程中电极是稳定的。其优异的性能可通过核壳结构中发生的两种电荷转移机制的耦合来解释。
